How to enable two playback devices at the same time. How to output sound via HDMI: down with extra wires

At the very beginning, I want to explain how the sound interface works on a computer, so that you understand what we will talk about next.

The computer sees any device that is capable of playing sound separately from others. If a typical computer has only one sound card, whether built-in or separate, then in some cases there can be many more of these devices.

In order to enable a person to control these devices, as well as to automate the playback of sound in general case, Windows computers have a special item in the sound output settings called "default device".

How to get to the control panel for audio devices in Windows

In the lower right corner of the screen, find the clock, to the left of it there will be the “Speaker” icon, right-click on it.

In the pop-up menu, select the "Sounds" item and click on it with the left mouse button.

You have reached the menu for controlling sound-reproducing devices in Windows. For the purposes of this article, we are only interested in the Playback tab.

What does "default device" mean?

This menu item shows us which device in this moment responsible for audio output or audio recording.

For example, if your computer has a lot of sound-reproducing devices installed, then this setting will show which device is currently playing sound.

Default audio output device in general

Imagine that you have only one sound-reproducing device in your computer - a sound card built into the motherboard.

There will be only one in the list and, of course, it will be the default device and you will not experience any problems.

However, if you connect USB headphones or a USB speaker to this computer, then 2 devices will appear in the list.

If you connect a monitor with built-in speakers to your computer, there will already be 3 devices and this list can go on for a very long time.

Therefore, it is important to understand how to adjust and configure Windows so that you can listen to sound through the device that you need.

Let's say you have one sound card and you have connected a monitor with speakers, while you already have good speakers that are connected to the sound card.

Of course, the sound quality of individual speakers will be better than those built into the monitor, so in order for the sound to be output from individual speakers, we need to select the sound card as the default playback device.

After we have selected the sound card as the default device, all sound from the computer will be output through it.

Selecting an audio playback device in the application

Let's return to our situation, when we have 2 sound reproduction devices: speakers built into the monitor, and a separate sound card.

In the settings of all such applications there is an item that allows you to select the audio and recording devices that will be used when this application is active, regardless of which device was selected by default in Windows.


Let's go to the audio settings of the Discord program. We see that we can select separate devices for recording sound and its output. What does it give us?

We can choose the same sound output device that is used for everything else, or we can choose a separate one. Thus, we can separate several audio streams for output to different devices.

For example, you have good external speakers that you use for sounding the game, and there are speakers built into the monitor that you do not use at all. By setting the audio output devices inside Discord, you can make the voice of your interlocutors output through the speakers in the monitor, and the sound of the game would be output through good external speakers.

For this you need to Windows device select external speakers by default, the game will see these settings and use it for itself. And in Discord, we will select the speaker output device in the monitor. Now all the voices of the interlocutors will be voiced by the monitor, and the game will have good speakers.

As you understand, this is just an example, you can choose any sound devices as it suits you or makes sense.

In the same way, you can choose different recording devices if you have several microphones. For one application, one microphone will be used, and for another, the second, or vice versa.

USB headphone connection vs. normal connection

Is there any difference between a connected device via USB and using a standard TRS jack?

Yes, there is a difference. It lies in the fact that any additional USB device, which is capable of playing sound, is considered separate from the others by Windows and can be controlled flexibly. While your sound card is seen by Windows as one device, and if you connect speakers and headphones to it at the same time, Windows will still see them as one sound-reproducing device.

But what if you want to switch between speakers and headphones that are connected to the same device?

There is a solution, but I will describe you only a general algorithm, because. each of the sound-reproducing devices may differ significantly from the other in the interface of the proprietary application or settings.

Make sure you have the latest drivers and proprietary software for your audio device installed on your computer. This is a prerequisite.

Is it possible to customize automatic switching from speakers to headphones and vice versa?

Consider a situation where you have one sound card to which you have connected headphones and speakers at the same time.

You connected the speakers to the green output on the back of the computer, and the headphones to the audio jack on the front of the computer.

If the front panel is connected to the sound card correctly, it will automatically switch between speaker and headphone output by the sound card software.

Windows will always be sure that the sound is output through the sound card, and will give it the entire audio stream for processing and output. The sound card will independently detect whether headphones are connected or not and output sound to them.

How to switch audio output to headphones if the front panel does not work

Some sound cards can change the assignment of the jacks on the back of the computer depending on the situation. For example, in some cases the line input (usually marked in blue) can be used as a separate headphone input.

Do not connect headphones to the line-in unless you are sure that it is now working as a headphone input. Otherwise, you risk damaging your headphones.

You can find out if your sound card supports this mode of operation either in the sound card settings or by reading the instructions.

If the sound card can use the line-in as a headphone output, then your problem is solved and when you connect headphones, the sound will automatically be redirected to them.

If the sound card does not support this mode of operation, you will have to turn off the speaker jack manually, then connect the headphones to the audio jack (usually marked in green).

At the same time, in the settings of the sound card, it is necessary to turn down the volume level to the minimum before connecting the headphones and switch the green output mode to the “headphones” mode, if possible.

If the sound card continues to work in "speaker" mode, and you connect headphones, this may damage the headphones due to too much current that the sound card will generate for the speakers to work.

Switching sound output from speakers to headphones using proprietary sound card software

In some cases, the sound card will either have a separate output for connecting headphones, or a separate mode for outputting sound to headphones through a common audio jack, which must be activated through a proprietary software.

For example, I use my sound creative card sound blaster ZxR.

In my case, I need to manual mode switch the sound card operation mode from speakers to headphones, but you do not need to physically switch the jacks.

This is not very convenient, but fully justified, because. this sound card has two physical jacks for connecting headphones and speakers, which have different signal amplification schemes and it is not possible to switch them automatically due to the design.

This is not very convenient, but it is fully compensated by the excellent sound quality.

The initial sound setup on a personal computer or laptop begins with the installation of drivers for the sound card. Of course, the latest modern operating systems, such as Windows 7, are able to determine the model of the sound device, regardless of whether it is built-in or separate, and install the necessary supporting software. Of course, this option is not suitable for owners of sound cards that came out recently.

If the OS did not install the drivers automatically, then do not despair. We need to start from the very beginning, namely, to understand exactly which sound card is installed on your personal computer. They exist in three types: 2.1, 5.1, 7.1. At the very beginning, when installing special drivers, using tooltips, you can easily determine this. And already, depending on the type of sound card, you can start setting up sound on your computer, knowing what kind of sound you should get as a result.

How to set up speakers on a computer: step by step instructions

First you need to turn off the computer, completely de-energizing it. Then connect the speakers to the connectors that match the colors of the cords (usually these are green color). Also, Line Out may be written on the connector.

After you connect the cords, you need to turn on the computer. Then, regardless of whether you have Windows 7 or Windows XP installed, you select "Start" - "Control Panel" - "Sound".

In the "Sound" menu, you need to find the "Audio speaker settings" tab. There you will be able to select the correct speaker layout (left, right), as well as confirm that their appearance matches that of the sound card. All these parameters are also easily configured with the help of video tutorials:

Speakers on the computer do not work - what to do?

If there is no sound on your personal computer, this is rather bleak. Here, tips on how to set up speakers on a computer will not help you. You need to carefully understand the nature of the problem.

To begin with, you need to exclude the possibility of damage to the equipment itself - headphones, speakers. To do this, you can connect them to another audio source. Then you should pay attention to the software (since hardware failures are best left to a specialist). In the "Control Panel" you need to select "Administrative Tools" and there find the Windows Audio service. It should be in the "Running" state. If everything is in order, but there is no sound, you should contact a specialist. Setting up sound on a computer is a fairly simple and intuitive procedure. However, if you are not sure of your knowledge, then you may need to seek the help of a more experienced friend who will help you set up the speakers.

The release of new operating systems also brings unpleasant innovations: someone does not like new design and the lack of familiar buttons, some find it difficult to new ways of interacting with the system and setting it up. Let's get started with Windows 7. How to set up sound and make it of high quality - you will learn about this from this article.

Sound settings in Windows 7 are carried out through the control panel and allow you to configure the microphone, speakers, sound effects. The sound setting method is different from the setting in Windows XP. Some changes have been added to the control panel that may seem unusual for users of other operating systems. But, in fact, there is nothing complicated in setting up sound in Windows 7.

Let's go to the control panel. In order to access the sound settings, you need to select the "Hardware and Sound" -> "Sound" section - quite logical, in general. We will open the settings window, the interaction with which we will study.

The audio settings window is divided into several tabs: playback, recording, sounds and communication. Let's get acquainted with them in more detail.

Sound playback settings

The Playback tab shows us a list of devices that can play sound. Devices that are currently in use are marked with a green checkmark, and devices that are disabled are marked with a red arrow pointing down. Here, devices are not only physically connected to a computer, but also those that can be connected in principle - i.e. sound adapters for which drivers are installed. Select the active device and click the "Configure" button. Here we can configure the playback device.

First, we configure the speakers depending on the number of sound channels. If headphones or conventional speakers are used, then our choice is "Stereo". If you have a more advanced audio system connected, then you can select "Quadrophonic" or "5.1 surround sound" or the same, but in the "7.1" option. By clicking Next, we can specify the location of the speakers, which ones are full range and other useful things.

If on the "Playback" tab, click the "Properties" button, then we will see a window with additional settings for the audio device. Here we can turn the device on or off; change its icon and specify the sound format, adjust the sound playback effects.

Sound recording

Let's go back to the Windows 7 General Settings window. How do I adjust the recording sound? This is also easy. The Recording tab provides similar settings, but now for audio recording devices. If you select a microphone and click the "Configure" button, the speech recognition window will open. Unfortunately, Windows will inform us that speech recognition is not supported for the Russian language. The "Properties" button can be of more use to us, clicking on it opens a tabbed window. setting up sound in Windows 7 is not the most difficult thing to do, is it? On the "General" tab in the properties of the microphone is displayed short information about the device. The "Listen" tab allows you to connect a player or other devices to listen to music; on the “Levels” tab, we can change the volume and gain of the microphone, and on the “Levels” page, we can adjust the bit depth and bitrate. The Enhancements tab gives us the option to enable various sound effects.

The other tabs of general audio settings in Windows 7 are also useful. On the "Sounds" tab, we can change the used sound scheme, and the "Communication" tab allows you to reduce the volume of sounds during conversations - convenient and understandable! We hope this article has helped you get familiar with Windows 7. How do I set up sound? It's easy, because now you can share your experience!

Regardless of the purpose for which it is purchased Personal Computer, it will always be used as a multimedia center for watching movies and listening to music. Even the “weakest” computer can easily cope with this task, so before you start using your computer as a multimedia center, you need to figure out how to set up sound on your computer. It is assumed that readers have already checked the volume level and installed (and downloaded from the Internet) all the necessary codecs ( K-Lite Codec pack). Without these two steps, anyone can have playback issues.

Quick Setup

Regardless of what does not work, proceed to the lower right corner of the desktop. In the tray we find the speaker icon, if necessary, click on the arrow.

Adjust the volume if necessary. Right-click and then select the item depending on the nature of the malfunction:

1. For sound, playback devices.
2. For voice - recording devices.

Playback devices

Entering the sound window, first of all, we right-click and check the boxes:

• Show disabled devices.
• Show disconnected devices.

The difference between them is that the former are disabled programmatically, for example, through the task manager, while the latter are absent at all, could be deleted, or even not used initially.

Standard analog output

On the screen is a typical set of devices. Speakers are outputs located on the rear panel. To verify this, double-click on the icon.

Here is the color breakdown. Due to the fact that the translation into Russian is crooked, a beginner may not understand what is at stake:

1. Green - left/right column. In a surround sound1 system, these are the front speakers.
2. The center and subwoofer channels go to the orange port.
3. Gray - rear (rear, side) speakers, left and right.

HiFi systems around 5.1 usually have polar outputs - two for each speaker. Therefore, you need to find an adapter for the computer. As for the usual stereo, the jack is already soldered there, all that remains is to connect it to the green input. The pinout of the 5.1 adapter in our case is as follows.

Knowing the layout, you do not need to be afraid of further options (because the list is extensive). Let's take a look at what each setting means.

At the top, it is proposed to change the settings of the entire sound at once. At the moment, the level is 47%. By clicking on the speaker icon, you can instantly turn off all the speakers, there is a balance next to it. But there are 12 more settings! They shouldn't scare us:

It remains to be added that by changing the level of the orange connector, the subwoofer and the central speaker are simultaneously regulated, and the gray one - both side ones. Only inscriptions in - inputs can lead to confusion. In fact, some of the connectors are audio outputs. We didn't say anything about blue. This is a line level analog input, similar to a (pink) microphone. The Improvements tab is proposed to be considered below.

Headset on the front panel of the system unit

The second on the Realtek HD Audio 2nd output list is the front panel audio jack. A red arrow means it's not connected. As already mentioned above. This option means that motherboard there is a free connector F_AUDIO, where you can get a headset. A typical view is shown in the picture.

If you look closely, you can see - the second bottom pin from the left. This is the key by which the layout of the connector is determined. The electrical interface is shown on the screenshot.

The pinout will help to connect almost any headset here. It should be noted that two different physical interfaces can go to F_AUDIO:

• AC'97.
• HD audio.

The table is given for the second case, because the first one is becoming obsolete. But in the specification for the motherboard, you need to clarify what signals this connector comes with. In addition, you can separately find internal USB ports for headsets, but usually no one uses them, but instead they use those located on the system unit case. The photo shows a typical combined module for the front panel of the system unit from USB and audio jack. The two connectors differ from each other by the position of the key.

Digital audio output S/P-DIF

The last item in the playback devices menu works fine, but the description says something about a mysterious internal ATAPI port. You will not find the decoding of these words anywhere on the Internet. It's actually just an S/P-DIF connector that's not on the rear panel. The slot on the motherboard is empty. Why might S/P-DIF be needed when setting up sound?

The interface was introduced in the 80s (XX century) by Sony and Philips after the release of the first digital CD players. To play music, it was necessary to perform double analog-to-digital conversion (reverse and direct), which reduced the quality. S/P-DIF delivers stunning sampling rates up to 768kHz at peak performance. The bus bitrate is typically between 2 and 3.1 MHz depending on this setting:

1. 2 MHz for 32 kHz sampling rate (satellite receivers).
2. 2.8 MHz for 44.1 kHz sampling rate (CD players).
3. 3.1 MHz for 48 GHz sampling rate (digital recorders).

To evaluate the possible usefulness of this connector, let's pay attention to the supported interfaces tab.

• DTS audio. Used to play HD quality video and Blu-ray discs. Supports 5.1 and 7.1 speaker system depending on software implementation. Suitable for connecting home theaters.
• Dolby Digital - in its usual form, the same 5.1 interface. The difference from DTS is in the capabilities of the connected equipment (players, home theaters, etc.).
• Microsoft WMA Pro Audio. Used by some players, such as online at nbcolympics.com/video.

All three varieties provide transmission digital sound high resolution for complex acoustic systems. Since they are transmitted over the same channel, the process is completely transparent to the user. In some cases, you will need codecs or drivers. S/P-DIF is a 3-in-1 hybrid output port for maximum compatibility with external equipment.

How to use S/P-DIF

From the configuration of the motherboard, it can be seen that the manufacturer (Gigabyte) does not really care about the S/P-DIF digital output. Instead, a high-performance HDMI port is present on the rear panel. This is a hybrid interface for transmitting audio and video information over a single line. The only problem is that the cable is not cheap, it is rarely supplied with equipment and is not supported by all devices. Speakers with HDMI interface extremely difficult to find, however, the same can be said about S / P-DIF (for example, Polk Audio Woodbourne).

The photo shows that the connector is represented by only two pins. Rumor has it that Gigabyte uses the ALC883 transmitter here, which can be directly connected to the 75 Ohm optical or coaxial input of any equipment. To do this, you need the appropriate cable. One of the pins is a circuit ground, and the other is a digital audio output. For docking, a pin connector from a system fan (cooler) is suitable. The ports were found on e-bay (ebay.com/sch/-/175673/i.html?_nkw=spdif). True, they are not cheap. If possible, you need to ask for connectors at the nearest PC repair shop, sometimes they agree to sell components at a reasonable price.

Some, even older, motherboards (Asus A7N8X-X) have an S/P-DIF connector with an input. This allows you to record sound here and perform some other operations. In this case, there may not be 2 pins, but more, for example, 6. Their functions are described in the user manual (see photo).

HDMI

Analog sound will never be the best. Therefore, if it is not possible to use S / P-DIF, then you need to buy. This digital interface is commonly found on modern motherboards. Its version must be found in the user manual. Starting with 2.0, the interface supports the transmission of as many as 32 independent channels. Of course, HDMI is compatible with DTS and Dolby Digital, mentioned above in connection with S/P-DIF. HDMI is aimed at movie lovers, not music lovers, because it allows high-definition video to be transmitted simultaneously.

To use the interface, you need to buy a cord, and an input connector will be found on the home theater. From what has been said, it should be clear that it will take 5.1 or 7.1 (including +2) to enjoy all the benefits. Otherwise, there is no need to use such sophisticated equipment.

Recording devices

This topic has actually been covered. An analog microphone usually plugs into the pink jack next to the headphones, and a USB headset sometimes requires a driver to be installed. The author has seen one village system administrator (pop. 2,500) say that sophisticated headphones don't require a driver. The fact is that in the villages they do not sell really high-quality equipment, and not everyone knows about it.

A composite USB headset is identified in Device Manager as a composite device. And it does not work, although sometimes (we did not see this in person) you can hear something in the headphones. This is not suitable for Skype and communication, and it is still recommended to install a driver. Because fancy headphones can often have their own controller inside.

The main problem for users is that zero gain is written in the microphone settings. So you talk, but you can't hear. It fixes itself in a couple of minutes. At the beginning it was said how to enter the playback devices, and now you need to select the recording devices. Set the checkboxes in the context menu as indicated above and change the gain. I would like to draw attention to the fact that manufacturers also have errors. For example, our microphone supposedly stands on the front panel, which is not true. It is plugged into a jack next to the speakers.

Checking the performance is carried out with a slight click of the fingers in the reception area. In this case, the indicator in the right part of the window will partially turn green. If this does not happen, then the sound does not come, and the communication is not to blame. Double-click on the working microphone and go to the Levels tab. Here all the scales need to be set to the maximum. Most programs adjust the headset volume on their own, and you don't have to worry about it. If the indicator now turns green when clicked, then everything is in order. Otherwise, we check the drivers, switches on the microphone, because the device does not work correctly.

In the window, in addition to the microphone, there is also a stereo mixer. This device is a system device, you will not find it on the motherboard. It is responsible for mixing channels. And if you want to capture full sound, and not just a microphone, then you should select the stereo mixer as the default device. Other programs (Audacity) allow you to make changes on the fly. A line input is a blue jack (see above).

Skype

Now it is not necessary to install Skype, because an online version has appeared (web.skype.com/ru/). To do this, you need to install a plugin on the browser.

After that, you will need to give permissions to the firewall, and you can start chatting. The downside is that there is no test call option. But if everything is configured according to our instructions, then there should not be any special problems. To check the microphone, use any audio capture program, including the built-in Voice Recorder in Windows. In the new Windows 10, a warning will be displayed when the microphone is activated, which is an additional guarantee and at the same time a signal to perform a check.

This means that apps are not allowed to use the microphone. Then here, in the sound recording, you need to go to the parameters and give permission. Otherwise, the microphone will not work.

In the installed Skype application, internal settings simultaneously change the system microphone gain. You need to remember this and check them periodically manually according to the scheme described above.

How sound is played on a PC

To begin with, it is worth understanding how the computer reproduces sound. In analog interfaces, a digital binary signal is converted from music or video files to continuous. First on the path of the chain of converters are software or codecs that decompress the audio file and allow the media player to read the audio data further. After processing, data from the central software core enters the sound card, where the binary is converted to analog sound and its preliminary amplification takes place. Further, the information is sent to a sound reproducing device, headphones or speakers.

There are various formats, and each has its own specifics, which the volume of the review does not allow talking about. Therefore, it is usually considered sufficient to download from the Internet and install K-Lite codec-pack. This package comes with its own very good player.

Adjusting the sound on the computer in the operating room Windows environment is performed both with the help of standard system tools and with the help of third-party utilities (which are better not to use). Below we will consider setting up sound using standard tools that are on any computer. To do this, go to the "Start" menu, then "Toolbar" and select the icon that says "Sound". The settings that can be made using this standard utility are as follows:

All of the above actions will be possible only if the drivers for the interaction of the sound card and the motherboard are correctly installed. These drivers are usually included on a disk bundled with the card, or on the Realtek website (rarely on another). To check if the drivers are installed correctly, proceed as follows.

In the "Start" menu, hover over "My Computer" and open the properties menu with the right mouse button. Go to properties, then click on the line that says "Advanced system settings" (for Windows 7 and higher, for Windows XP this step is not required) and in the window that opens, go to the "Hardware" tab. After that, click the "Device Manager" button and you can see all the devices installed in the system. Next, expand the node "Sound, video and game controllers" in the tree and make sure that the devices are functioning correctly (there is no yellow icon with an exclamation point). If there are any problems, you should reinstall the drivers.

Sometimes situations happen that we turn on our computer, but there is no sound. The same situation may appear after reinstallation operating system. What to do in this situation, how is it carried out computer sound settings Let's try to figure out this issue.

First you need to make sure that your speakers or headphones are connected not only to the PC itself, but also (in the case of speakers) to the mains. If everything is in order here, then we translate our gaze to the lower left corner of the monitor to the "speaker volume control", it looks like this:

Often there are situations that the volume slider simply stands at zero. If everything is fine here, then we proceed to check the drivers. This check is performed differently for each operating system.

Sound settings on Windows XP

Setting up sound on a Windows XP computer is carried out as follows, first click the "Start" => "Run" or "Run" button, after which a window will appear, in the line of which you must enter: "devmgmt.msc" and click the "OK" button. Now the Device Manager will appear in front of you. In general, it should be said that if there is a yellow exclamation or question mark on any device, then this means that the device does not work correctly or does not work at all. So, in our case, if you have an exclamation mark in the "Device Manager", "Multimedia Controller", as in the picture below, then you have a problem with the drivers.

To do this, you need to find your motherboard box, which should contain a disk with drivers for the motherboard. Using this disk, install the drivers for your audio controller.

But bad luck, you don’t have such a disk, and what to do in this situation? The solution to this problem is to search for drivers on the Internet. Some will immediately say that this is hard, and that a huge number of drivers will need to be shoveled, but this is not the case with our advice. So, open the device manager => on the “Multimedia controller”, which is highlighted with an exclamation mark, right-click => Properties. A dialog box appears in front of us, in which you will need to go to the "Details" tab, and from the list that appears, you need to select the equipment ID, then you should get the following

Each top line will be different, as each audio equipment is different. We press RMB on this top line, copy it, go to the devid.info website.

In the line shown in the picture, paste your code and click "Search". Congratulations, you have found your audio driver. Download for your operating system, install and everything should work.

Windows 7 and Windows 8

Setting the sound to Windows computer 7 is carried out by the same method, only to go to the device manager, you can use the following method, on the "My Computer" icon, click RMB, "Properties", a window appears

And on the right side, go to the "Device Manager". Setting up sound on a Windows 8 and 7 computer is more simplified. Again, we are looking for our audio device with an exclamation point, right-click on it => Update drivers ... => Automatically search for updated drivers.

With this approach, the operating system itself will search the global network for drivers for your audio device, and you do not need any program to configure sound on your computer. But again, there is a problem when there is no disk with drivers from the motherboard and access to global network. Here the only way out remains, again, we copy the equipment code of our audio device, insert the flash card into the PC, create on it Text Document, open it, insert the equipment code, save the document, and go with a flash drive to a friend, relative, acquaintance, in general, to anyone who has access to the global network. And with the help of this code, we are looking for drivers for our audio device, as described above. Download the driver to the flash card and install it on your PC.

We hope this article helped you solve your problem.

Typical problems with Windows are mainly related to the fact that it was not possible to correctly configure the hardware in the computer. For example, speakers or speakers may not work. There is no sound for various reasons on the computer, so first you need to put aside the panic and try to restore normal operation on your own.

Checking the technique

Can't listen to something? Let's dive into the root causes of the lack of sound and try to configure the sound card. You need to be sure that everything is working properly on the computer. For this you need:

• Open the Start menu and select the Windows Control Panel there.
• Then click on the System and Security category.
• Then, in the special section System, click on Device Manager.
• If you are asked for a Windows administrator password, then you must enter it.
• After that, double-click on Sound, game and video devices.

Now you should see if there is a sound card in the list that opens. If it is not there, you should read the instructions from the manufacturer on how to set it up. It is also useful to look at the Other Devices tab, the sound card may be there. A laptop is usually easier to set up in this regard, since there is no sound card. Instead, a special sound processor works.

Sound in Windows may not work if there are problems indicated by a yellow question mark next to the sound card:

• Right-click on the sound card and select Properties.
• After you need to go to the General tab and check the Device Status.

Usually, in such cases, the sound in Windows can be restored by simply installing new drivers on the computer. If you don’t have time to poke around the net for a long time to find and install the necessary driver, you can try a good program called Driver Genius.

After this program is launched, it finds all the necessary drivers on the network (including for sound) and can independently install or restore them in Windows.

Connectivity Check

If there are speakers, but there is no signal from them, then you need to check if they are connected correctly. On almost all computers, the sound works from three connectors that connect to the sound card. It is important to understand here that the speakers must be connected to the linear sound output.

But what if you are not sure which connector is responsible for what? In this case, it is worth going through all the options on the computer, alternately connecting to each socket. The same goes for headphones. It is interesting to know that in almost every computer, after connecting the headphones, the sound turns off automatically.

Power check

The speakers may simply not be connected to the mains, so there is no sound for physical reasons (no current). Naturally, you need to connect the speakers to the network, and the speakers will start playing sound. The same applies to the controls through which the speakers increase and decrease the volume. Often on laptops, the volume control is turned to minus, so small speakers are simply not audible.

You need to open the volume through the following path:

• Click the Start menu;
• Then select Control Panel;
• Click Hardware and Sound;
• Next item Sound;
• At the end Adjust the volume.
• Then the volume slider needs to be raised up.

It is important to see if the sound is completely muted in the mixer. Also, some laptop models have external wheels in order to adjust the sound fed to the speakers. I need to check this wheel.

Checking programs

But what if, after all these manipulations, it was still not possible to configure? It's okay, you just need to check the volume level in the programs installed on Windows. Maybe it just doesn't show up there. Each program has its own controls so that you do not need to switch to Windows settings, but quickly turn down or turn up the volume. So it's better to check the settings everywhere (speakers, headphones, settings) to eliminate all the reasons for the lack of sound on the computer and then restore normal operation.

Various operating system errors are directly dependent on users. It is enough to download a malicious program that is attached to free files on the network, and the problematic failure of normal operation will begin. However, if you keep a record of all the software that is installed and removed, then you can keep the system under control. So the speakers will sound, and the picture will be correctly displayed, and the programs will function correctly.

On a computer, users often ask how to output sound from a microphone to speakers or headphones. In this short article, we will describe two ways at once how this can be done.

Method number 1. Sound settings in Windows.

In order to output sound from the microphone to or headphones, you must first open the sound settings. To do this, right-click on the speaker icon on the taskbar and select "Recording devices" in the window that appears.

After that, the "Sound" window will appear in front of you, opened on the "Record" tab.

This window can also be opened through the "Control Panel". To do this, go to the "Hardware and Sound - Sound" section. And then, in the "Sound" window, open the "Record" tab.

So, after you have opened the "Sound" window on the "Recording" tab, you need to go to the properties of the microphone. To do this, select your microphone with the mouse and click on the "Properties" button.

In the properties of the microphone, go to the "Listen" tab and enable the "Listen from this device". Enabling this function will allow you to output the sound from the microphone to your speakers or headphones.

To save, close all windows by pressing the OK button. In order to remove the microphone sound from speakers or headphones, simply go to the microphone properties again and turn off the "Listen to this device" function.

Method number 2. Sound card settings.

You can also output the sound from the microphone to the speakers or headphones using the settings of your . To do this, open the sound card settings and find the microphone settings there.

Connecting audio from your computer to your TV expands its capabilities by improving the sound quality of music or movies. There are several ways to do this, they all have their pros and cons, so it is necessary to give preference to one or another method, taking into account the characteristics of the technique and its capabilities. Before connecting sound from a computer to a TV, you need to make sure that your devices have one of these connectors.

Main types of connectors

Almost all modern technology is equipped with one of these types of connectors. They are designed to connect external storage media, video and DVD players, as well as other digital equipment, which includes a computer.

The most used types of connectors are:

• HDMI;
• WiFi;
• RJ45;
• RCA cable.

Ways to connect sound from a computer

Via HDMI connector

Audio output through this connector is the most popular, as it causes less problems and malfunctions, and the sound quality remains good. This cord may be supplied as part of some digital devices and will be sold separately.

There is no need to purchase a cord that is too expensive, because regardless of the price, the same materials are used in its manufacture, which do not change the sound quality.

To connect the TV to the computer, you first need to disconnect both devices from the power supply, and then connect them with a cord. This connection method does not require any advanced settings, just set your TV to HDMI output as the audio source.

Possible problems when connecting devices

• If there is no sound, then you need to set the TV as the sound source using the computer. To do this, by right-clicking on the sound icon in the lower left part of the taskbar, select the "Playback devices" item from the pop-up menu. From the list, you need to select your device, right-click on it and check the box next to the "Set as default" menu item.

At the time of setting, the devices must be connected to each other. If the computer does not see the TV when the HDMI cable is on, then you need to restart it and repeat the setup procedure again.

• You also need to make sure that the video card supports audio playback via HDMI output. Often all modern devices are equipped with such a function. However, some of them come with a special jumper that helps create a "SPDIF out" connector on the system board with the "SPDIF in" connector on the graphics card.
• You can solve the problem if you reinstall or update the drivers for the video card.

How to connect sound from a computer to a TV using a Dvi cable?

The second most popular method, which is used when it is impossible to connect via HDMI output. Connectors of this type are divided into three types: digital, analog and combined. However, with sound transmission through this connector, not everything is as simple as with the previous one, since everything depends on the video card used in the computer, because not all of them support sound playback via the DVI output.

In the case of transmitting not only audio, but also video signal to a TV, you must use a DVI - HDMI cable or connect devices using DVI-D - HDMI adapters, and then an HDMI-HDMI cable. Such a complex connection system is explained by the fact that the video signal does not always pass through the DVI cable.

The disadvantage of this method is also a complicated setup process compared to the previous option. To begin with, in the TV menu, you must select the DVI connector as the signal source, while the computer and TV must be connected to each other.

Connection via VGA cable

This is an outdated method that loses to the first two in terms of ease of connection and playback quality. Therefore, it is often used in outdated devices where it is impossible to connect using other cables.

What problems can arise when connecting?

Very often, the VGA output is already occupied by a computer monitor, so in order to connect another device, you need to purchase a special adapter, and then a cord for audio playback.

Main disadvantages

VGA is not intended for sound transmission, it can only be used as an additional element, to which it is necessary to connect a special cable. This option is not only costly, but also more complex and of lower quality compared to other methods.

How to transfer sound from a computer to a TV via WI-FI

This method puts forward additional requirements for the TV - support for DLNA technology and the presence of a media player. Modern plasma models are equipped with such a function, so this connection method can be considered as an alternative to HDMI.

Connection setup

After making sure that the TV is equipped with a built-in WI-FI module, you can start setting up.

1. First you need to configure the router so that it can work in DHCP mode.

When setting up, be sure to assign a password that will protect local network from unauthorized entry.

1. In the TV menu, you need to find the “Wireless Connection” item, and then find your network and enter it with a password.
2. To transfer sound to a TV, it must be installed on a computer special program- media server. Then, with the help of this program, access to files and folders containing music or movies is opened.
3. To switch sound from a computer, you need to open the media server, and select Ethernet as the playback source on the TV.

What is the disadvantage of connecting through a WI-FI router?

When playing sound on a TV, a large load on the local network is created, which can lead to a decrease in speed.

Connection via RJ45

When connecting this way, a special network cable, which can be found in stores under the name "twisted pair". As in the previous method, the TV must support DLNA data transfer technology.

A router is also used here, which is configured in the same way as through a WI-FI connection. However, using this device may result in slower speeds. Therefore, it is better to give preference to an additional network card.

The setup takes place according to the same principle as through WI-FI, and you need to connect through a media server.

How to output sound from a computer through an RCA cable

This method allows you to connect even the most outdated models of computers and TVs. Such a cable is called a "tulip"; it can have two or three sockets, each of which is responsible for transmitting a separate signal. Yellow is video, white is left stereo audio, red is right stereo audio.

Devices must be disconnected from power before connecting. Then, in the appropriate holes (often they are indicated by color), it is necessary to attach the "tulip" connectors. After that, in the computer settings, you need to expand the desktop to fit the TV screen, and switch the TV to “Video” mode.

The most preferred methods among all those described above are connections via an HDMI cable and via twisted pair or WI-FI router. It is these options that are able to provide sound quality, connection reliability at the proper level.

The video shows in detail how to connect a TV to a desktop computer via HDMI and MPF. First you need to select cables without adapters and make sure that the necessary connectors are available on the devices. Then the connectors are connected, and the TV and computer are set up.

How to connect sound from a computer to a TV

Many music lovers keep digital recordings of their favorite tracks on their personal computer, but it is better to listen to them with the help of a modern audio system. An excellent option is a home theater - surround sound, the subwoofer produces an excellent low bass sound. But how to make a connection so that the sound goes from a laptop to a TV, and then spills throughout the room through high-quality speakers? There are quite a few different ways to solve the question of how to connect sound from a desktop computer or laptop to a TV.

Main Connectors

Each household appliance has connectors for connection, the main and quite often used ones are as follows.

1. High definition multimedia interface, abbreviated as HDMI. Its purpose is to transmit digital video and audio data. Recently, it has become fashionable to connect to the worldwide network through this port and cable.
2. Digital Visual Interface or DVI. It is designed to transmit a video signal to all modern monitors and LCD TVs.
3. A 15-pin video adapter or a subminiature VGA connector transmits an audio signal line by line, used on all modern television and audio equipment.
4. Wireless connection or the well-known abbreviation Wi-Fi, which has firmly entered the life of modern youth - you can connect through it and transfer data without a cable.
5. Registered Jack (connector) or RJ45 is a connector for connecting a computer or laptop to household appliances.
6. Composite RCA connector, patented in the early 40s of the last century, to switch the sound from the phonograph of the time to the amplifier. It is still applied.

All modern technology has several connectors of various types in its arsenal to facilitate connections. Connected through these connectors, a DVD player, laptop or other digital media is ideally combined with a TV for sharing information.

Connection options

Today, there are a huge number of cables on the market that allow you to switch different types connectors. Each type of connection has its own characteristics.

HDMI cable

This method is considered the most popular, because it rarely causes problems and malfunctions, the quality is at its best. high level. This type of cord is sometimes supplied with digital equipment, and in the retail network it can be purchased at any store.

When connecting, it is necessary to de-energize the products, connect the cable to the laptop and TV. This connection does not require separate settings, only when enabled in the menu section of the TV receiver, specify the source of the audio signal.

Advice! When buying a cable, do not chase the most expensive analog - they are all made of the same material that does not affect the sound range.

During the preparation and implementation of such a connection, a problem may arise: the sound does not go through the TV acoustics. We go into the laptop settings, select the TV as the source of the sound signal, put a tick in the "Use by default" box. Also check your video card - it should support similar playback. True, many manufacturers include a special jumper in the package to help create a connection; this should be displayed in the instructions. In order for the video card on the TV to work properly, you need to update the drivers, but only from the official website.

When setting up, both products must be connected, if for some reason the laptop does not see TV when the HDMI cable is connected, restart the computer and repeat all the settings.

DVI

This variety is used when it is necessary to switch the sound range from a computer to a TV. There are three main types of such a connection:

• digital version;
• analog way;
• symbiosis of both.

But with the help of this connector, the correct sound transmission does not always pass - the reason is in the video card of your PC. Experts advise to use special cable type DVI - HDMI or use a DVI-D - HDMI adapter along with a cable where both connectors are identical, i.e. HDMI type. Such a complex scheme of the whole structure has a very simple explanation - the video signal does not in all cases freely and unchanged pass through this type of cable. In addition, the settings have a more complex system than the first option.

VGA

A rather ancient method - it is rarely used and mainly on products of the old layout, where it is not possible to connect modern cables. This slot is always busy system block cord from the monitor, so you also need to purchase a special adapter and a cord for reproducing the sound range.

The disadvantages include the fact that this outdated cable connected to products does not transmit sound according to its characteristics - it is used as an additional element. The option is considered costly in terms of money, difficult to implement and does not have the required quality.

Wireless technologies

Many users often ask how the sound with home computer transfer to TV WI-FI assistance and what you need to buy. Your TV must have support for DLNA technology - an alliance of digital networks located in the house. This modern project allows the user to solve all problems - download any applications and updates, receive and transmit video images, digital music and distribute it among compatible home devices.

Today every flat TV family plasma models equipped with such functionality, so this method of data transmission is an alternative to the HDMI cable.

The settings are not difficult, but to complete them, you need to buy a high-quality router that works in the DHCP system - a technology that allows you to automatically assign an IP address to any device. When you are convinced that the TV is equipped with a special module, proceed with the step-by-step setup.

1. We configure the router to work in the mode At the same time, it is necessary to install a very strong password(at least 10-12 characters) to protect the device from intrusion.
2. In the TV menu, we look for the “Wireless connection” section, find our network and enter it.
3. To transfer sound from a laptop to TV, you need to install the “media server” program on your PC / laptop, then use it to open access to the necessary virtual media in which the music is stored.
4. To switch sound from a PC, you must first open installed program and in the TV settings, select "Internet" as the playback source.

The disadvantages of this type of connection, experts attribute a significant load on the local home network- this may affect the speed of the Internet.

RJ45 network cable

This type of cable is sold in the retail network as "twisted pair". For such a connection, the TV must support the data transfer technology similar to the previous version. Additionally, you need to purchase a router, which leads to a slowdown in the connection speed - you need another network card. The setting is done in the same way. wireless network.

PC+TV via RCA

This method is useful for connecting outdated PCs, laptops and TVs, to which modern cables simply will not fit. Experts call this type of connection "tulip", the cord may have two or three connectors, each of which is responsible for transmitting specific data or signal. Standard marking:

• yellow color plug - video signal;
• white is the left channel of the stereo audio signal;
• red color - right channel.

Professional masters advise using the HDMI option or a wireless type connection, in second place is the RJ45 type cable, because only these options can provide high-quality sound output and exceptional reliability.

How to connect sound from a computer to a TV

A large number of people face the need to connect a computer to a TV every day. This is a very good opportunity, because not always the size of the monitor and its location allows you to comfortably watch movies and other entertainment programs. In addition, the TV can be used as a monitor if the latter is out of order.

• 1 Connector types
• 2 HDMI
• 3 DVI, VGA

• 4 WiFi, RJ45
• 5 S-Video/SCART

Connector types

Modern devices to connect a computer to a TV, you can do it very quickly, while the image and sound will be of high quality. Almost any model is suitable for such a connection, including old kinescope ones. The definition of the process algorithm is directly determined by the type of connectors that the connected devices are equipped with.

The most popular interfaces (connectors) are:

• HDMI;
• RJ45;
• WiFi;
• S-Video/SCART.

After a thorough inspection of the devices and identifying one or more connectors from the above list, you can begin the process of connecting devices.

HDMI

This connector is considered the most convenient and, accordingly, the most popular. In addition to a clear image, it transmits sound High Quality. To connect a computer to a TV, you just need to have a special cord with the appropriate outputs.

First, the connected communications equipment is disconnected from the mains and the cord is connected. Next, the computer and TV are turned on, HDMI is indicated as the source in the settings of the latter. Image, sound will be played without auxiliary operations.

When choosing an HDMI cable, you need to understand that the materials used in its manufacture and, accordingly, the cost, do not affect the sound and image quality. Therefore, it is not necessary to buy an expensive wire.

DVI, VGA

To connect the image and sound from the computer to the TV, you can use other interfaces - DVI or VGA. The first option is more preferable. It is recommended to resort to the VGA-related method only if it is impossible to work with DVI. Often, when a user tries to connect devices using VGA, they are found to be busy with the computer monitor. This problem can be solved with the help of a DVI-VGA adapter, which makes it possible to make an auxiliary VGA from a free DVI. Using these interfaces, you can only transmit an image; to connect sound to a TV, you will have to buy a special audio cord.

WiFi, RJ45

To connect a computer to a TV via a network connector or Wi-Fi, the latter must meet two basic requirements. The first is the presence of a media player, the second is the ability to support DLNA technology. This technology allows devices to exchange files online. Thanks to it, the TV can work with files directly from the computer's hard drive, without the use of removable hard drives or flash drives.

The DLNA connection procedure includes two steps:

• connection of means of communication;
• installation of the DLNA server, its further configuration.

The first step depends on whether the TV has an RJ45 network connector or wifi module. Some models have both of these options at the same time. It is best to use a network cable to connect video and audio.

To connect the network connector of the TV to the router, you will need a "twisted pair" - a special cable. Finding such a cord is not difficult. However, the option with a router is not possible in all cases. Reason: video and sound on the TV gives heavy load on the router, which leads to Internet failures (speed reduction or loss of connection). Solving the problem by buying a more productive expensive router cannot be called optimal. It is better to install an additional network card, which will save money.

After connecting, they proceed to install the “Home Media Server”, making the appropriate settings. To play video and sound, you need to open the “Home Media Server” on your computer and run it. Next, you need to select Ethernet as the playback source on the TV, after which the explorer opens and the desired file is selected.

S-Video/SCART

With help this method you can connect sound and video even to an old TV. The main condition here is the presence of an “s-video” connector on the computer, and a twenty-one-pin wide scart connector on the TV. You also need to buy an S-Video cable and a SCART-audio/video/s-video adapter.

The connection process algorithm is as follows:

• The adapter is inserted into the TV connector. If there is a switch, the latter is placed in the Input position;
• connector connection;
• to transfer sound from a computer, you need to connect a special “two tulips” cord to the appropriate connectors of the adapter;
• the TV turns on;
• the computer turns on. After turning it on, the "Properties" item is called, where "we extend the desktop to the selected monitor";
• after switching the TV to the “Video” mode, the desktop of the computer is visible on the screen. Next, open the file and move the player window to the TV with the mouse, switching it to the “full screen” mode.

How to connect sound from a computer to a TV: 3 nuances

You don't need to buy expensive gadgets to connect sound from your computer to your TV We all love to watch the latest in the movie industry, but a standard PC monitor screen is clearly not a replacement for a large flat-panel TV. That is why today more and more craftsmen connect a computer to a TV and watch movies on the big screen. In general, the task of connecting is quite simple, but often there are problems with sound. A banal, but very problematic question - how to output sound from a computer to a TV?

Let's first of all figure out in which cases you should switch the sound from a laptop or PC to a TV. So, if you have both a computer and a TV nearby in one corner of the room, then it is not necessary to switch the sound to the TV. The picture can be displayed on big screen, while the sound continues to flow from the computer to the speakers. It is quite another matter when the computer speakers and TV are in different angles, or, even more banally, you don't have a good audio system and the TV sound is much better. It is in this case that you need to connect the sound from the computer to the TV, in other words, output it to another device.

To output sound from a computer to a TV, you need to connect them together using a cable

The execution of the task depends on the following nuances:

1. your software. Connecting sound on older operating systems often occurs in automatic modes. In new systems, such as Win 7,8,10, it is only necessary to manually transfer the sound to another channel.
2. Connection type. The output of sound, like pictures, to a TV can occur through a number of methods. We will discuss each option in detail later.
3. TV type. Depending on the model, you can make the connection active through the device menu or in automatic mode.

How to connect audio via HDMI to TV

In general, connecting sound and picture from a computer to a TV can take place in three main formats - via HDMI, DVI cables or the so-called tulip. The very first type of cable is the newest, it is compact, easy to use and versatile - high-quality video and sound pass through one connector. All you need to do in order to stream sound from your computer to your TV is to turn on the desired movie and set the appropriate settings in the menu.

Before playing the movie, you need to disconnect both devices, plug one end of the cable into the HDMI socket on the computer and the other end into the corresponding socket on the TV panel.

Depending on the model of the latter, you must either switch to HDMI mode, or wait until the device itself recognizes the connected computer. Next, everything that is shown on the TV should be displayed on the TV screen.

What can be surprises? In general, the problem with sound in almost 90% of cases comes down to one thing - you need to enable sound playback via hdmi on your computer. Otherwise, the video will go to the TV, and the sound, for example, to the headphones connected to the PC.

Solving the problem is simple:

• Right-click on the sound volume icon at the bottom right of the WIN taskbar (next to the time);
• Go to the "Playback Devices" menu;
• Choose from the suggested sources HDMI or TV (the PC often determines the device to which it is connected);
• Press desired device right click and select it as "default device". At the same moment, the sound will begin to go to the TV.

You can buy an HDMI cable at any store that sells computers or household appliances

When connecting a PC to a TV via a VGA cable, the procedure is the same as with an HDMI cable, but the picture quality will be slightly worse. However, in the case of connection through the so-called tulip, everything is a little more complicated. Let's look at this type of connection in more detail.

We use a tulip: how to connect a PC to a TV

In general, in all modern TVs There are already connectors for a long time for connecting cables of a new type. However, if your TV is old, then you will have to connect it to the computer through the so-called "tulip" cord. It is a bundle of three cables different color- yellow, red and white. It was for the multicoloredness that the cable was jokingly nicknamed the tulip. So, in this bunch of “colors”, the yellow cable is responsible for the sound, the white one for the left speaker and the red one for the right one. This is one of the very first systems for outputting sound and video from one device to another.

The connection looks like this: insert the cables certain color to the corresponding jacks on the TV and PC (jacks of the same color). Set the TV to Video or RCA mode and switch the audio output on the computer through RCA.

The downside is that through such an outdated cable you will not be able to output a high-quality HD picture, and you will have to forget about surround sound - a maximum of two speakers. The second problem is that most computers no longer have tulip connectors. And if you can still output sound through a tulip, for example, through a headphone or speaker jack, then modern video cards do not transmit video in this way.

Everything in its place: how to switch sound from TV to computer

If you have finished watching a movie and want to return to PC mode again, you must first disconnect the cable through which the devices were connected, and then put the computer into speaker or headphone audio playback mode. You can do this in the sound manager, where you select the default device desired channel such as headphones.

After connecting the cable, you need to turn on the sound in the corresponding menu

It's worth noting that it's easiest to make the switch if your computer and TV have HDMI cable jacks.

In this case, you do not have to disconnect wires for a long time, worry about settings, sound and video quality. All you have to do is unplug the cable and switch the audio source. By the way, on new Windows most often when you disconnect the cable, the PC itself will go into standard mode playback.

Instructions: how to connect sound from a computer to a TV (video)

Well, today it is not difficult to output sound from a computer to a TV. In total, there are several types of connecting a PC to a TV - these are HDMI, DVI and a tulip. The first method is the newest and allows you to transfer a picture to high resolution and surround, multi-channel sound, in addition, via HDMI, the connection is made with one cable. DVI is a slightly more outdated technology, the picture quality will be average, but the connection is also made with one cable. A tulip is three cables at once, while not all PCs already have connectors of this old type. You need to switch sound from PC to TV in the new operating systems in the sound manager menu, which can be found in the taskbar at the bottom right of the monitor screen, next to the time and date.

2 When connected via DVI in some models of video cards, sound transmission is also possible, then when using a DVI-HDMI adapter to the input HDMI TV both video and audio will be played. If you have only digital DVI on your video card (then the letter D is written), then you won’t be able to connect an adapter to VGA to it, because there is no analog signals. But if there are two DVI connectors on the video card, then they are written with a prefix in the form of the letter I and mean universal port with transmission of both analog and digital video signals. To such a video card, you can connect receivers of both analog signals and digital ones. Visually on the connector only with digital signals four contacts are missing around the horizontal slot. All contacts are present in universal DVI-I connectors. On the modern video cards DVI-D connectors are rare, mostly universal DVI-I.

3 When connecting via a DVI connector, pay attention to the presence of the HDCP (Content Copy Protection) function. Some TV models will refuse to work with this type of connection without HDCP. This is especially true for playing Blu-ray discs.

4 If you are connecting your TV to your computer as a second monitor, then the monitor and TV must be configured separately. In this case correct setting screen will say "Extend desktop to this monitor". You can display the settings of the program that plays the video on the monitor, or continue working on it while watching a movie on a TV screen.

5 Blu-ray and HD-DVD discs are now actively replacing DVD. On such disks there are films in a special film format - 24 frames per second. Moreover, if the computer uses a frequency of 50–60 Hz, the image “slows down”. The picture will be as clear as possible if you switch the video card to a refresh rate of 24 frames per second. However, this can only be done if the TV supports 24p mode.

Connecting sound from a computer to a TV

1 To get sound from AMD/ATI video cards, in the "Sounds and Audio Devices" control panel settings of your operating system (WinXP), you need to select the default "ATI HD Audio rear output" audio output device.

2 When connecting some graphics cards, there may be no sound with the HDMI to HDMI cable. There may be no sound on the video card itself and you need to use a special short cable from the motherboard (should be supplied with the video card) to send sound to the video card from “SPDIF out” (motherboard) to “SPDIF in” (video card). After that, connect the HDMI cable to the HDMI ARC input of the TV, and in the computer settings “Start-Control Panel-Sound-Digital Audio” make S / PDIF the default. Uncheck the box "disable digital output". And carefully read the manual for the motherboard and video card.

3 When poor quality sound check in the settings of the sound card or player output stereo sound or 5.1 or some other. Try changing the output from one mode to another.

4 When connected via DVI, sound can be fed from miniJeck on a computer to the “Audio DVI in” input, not to be confused with the Audio in input for a composite signal. If after this there is no sound, then look at the sound settings on the TV, you may need to switch the inputs.

5 In some models of sound cards, in rare cases, to supply sound to the TV, you need to pull out the speaker and headphone connectors from other connectors.

6 When connecting a video signal via a DVI-HDMI cable, some TV models will also take sound from the HDMI input, but the computer does not produce sound through DVI and, according to all the rules, the user connects the sound with a separate cable. So, to play sound, you may need to additionally specify in the TV menu that for this HDMI input you need to take sound from another input.

7 When using DVI-HDMI adapters, it is better to use it on the computer side and connect an HDMI-HDMI cable to it. This is in the case of using video cards that mix audio into the DVI signal using S / PDIF. If a DVI-DVI cable is used and there is a DVI-HDMI adapter already on the side of the TV, then the sound may not go through, because there are three types of DVI connectors (digital, analog and combined), and the cables are different and where the video card mixes the sound, to which Contacts are not known. Or maybe the cable just doesn’t have the contacts that are needed to transmit sound? The DVI-I dual link cable has the most complete set of conductors inside, and you need to look at the rest.

8 There is a menu item "Audio HDMI" in some TV models. When enabled, audio will only be taken from the HDMI input when an HDMI cable is connected. You need to know this if you are using a DVI-DVI cable, and there is a DVI-HDMI adapter in front of the TV and the sound is supplied by a separate cable. So with this connection and the active item "Audio HDMI" there will be no sound on the TV. When this menu item is disabled, the sound should work.

9 Sound, if not on the video card, is taken from the output of the sound card.

10 It happens that the sound does not pass due to wrong setting input/output in the sound manager on the computer. One inconspicuous item in the menu can ruin everything, look carefully at all the settings of both the video card and the sound card and the player.

11 In Windows XP, there are often problems with the SPDIF setup. The fact is that in this OS, the digital output is not displayed as a separate audio output device. That's why where will he go sound - depends on the driver. As a rule, analog and digital outputs are either duplicated, or when a digital output is connected, the analog output is disabled.

12 ATI video cards already have their own sound controller, so no other audio devices not required. In the case of audio output via the DVI connector, you must use a proprietary DVI->HDMI adapter. Check the availability of the adapter in the kit directly in the store where you make the purchase - the bundle may vary! You must use the adapter that came with your graphics card. Left adapters, as well as DVI->HDMI cables, will not work. The "correct" adapter contains a chip with a sewn number of something there.

13 Mobile NVidia graphics cards 8xxx series and above support audio transmission via HDMI in the same way as discrete ATI video cards, i.e. have their own audio controller, which is detected by the system as a separate audio output device (Realtek HDMI Output). As for the supported formats, it is reliably known about the output of 5.1-channel sound.

14 If you are sure that you have correctly configured the system, connected the bridge to NVidia, installed the driver for ATI, but the sound still does not appear, open the instructions for the TV and check if you need to specifically select HDMI audio reception in the TV menu, and what formats digital audio are supported.

15 If we want the sound to go to the TV only when watching a movie, then select the analog output as the default device (as usual). And in the settings of your player, through which you watch movies on your TV, select SPDIF (for NV) or Realtek HDMI Output (for ATI), respectively.

Yesterday my wife and I decided to watch a movie, but in order not to disturb anyone, it was necessary to distribute the sound simultaneously to two pairs of headphones. Some headphones are simple wired ones that simply intercept sound from speakers when they are connected to a laptop, and the second ones are wireless Qumi Concord connected via bluetooth. Is it realistic to do it standard means Windows 7?

It turned out to be quite real. Most computers these days come with a built-in sound card from RealTek. It is required that native drivers be installed on it, even not necessarily the latest ones, but not those that come with Win7 out of the box.

Now I have sound only in the speakers, and the microphone is used from wireless headphones. Open the Recording tab.

Then we turn on the display of all devices, even disabled according to the system.

I got a supposedly disabled software Stereo Mixer on my sound card. After that it needs to be turned on.

And choose to play it on your second audio output device. In my case it is wireless headphones. After that, the system will simultaneously output sound to the speakers (or the first headphones) and additional device such as wireless.
