HDMI: why is there no sound?

Today, when connecting a computer or laptop to a TV using an HDMI cable, users often complain about the lack of sound. In most cases, this common problem has a solution, you just need to be aware of it. In this article, we will talk about why there is no sound through HDMI and how to fix this problem.

Step-by-step instructions for setting up sound

So, you first need to be sure that your computer or laptop is properly connected to the TV. That is, your image is transmitted well, and the sound on the TV works. Check it again with your remote control for volume. When everything is correct, but the problem persists, follow these instructions:

On your computer or laptop, go through the "Start" button in the "Control Panel".
In the panel, you should find a section called "Hardware and Sound" and enter it.
In it you will see the “Sound” section that we need. In cases where you cannot find this item, you can use the search in the Start menu. To do this, in the line intended for the search, write “sound”, and your OS itself will give you the desired section in the “Control Panel”.
After entering the "Sound" section, a window should appear in which you will see four tabs - "Playback", "Recording", "Sounds" and "Communication".
We are interested in the first item - "Playback", which makes it possible to select a device whose parameters need to be changed. It displays the audio devices to which the sound is sent.
If there is no sound on the TV through the HDMI cable, then in this window, as a rule, there is a green icon in front of the “Speakers” item. And this is the reason for the lack of sound, since the sound is not transmitted to your TV through the cable, but goes to the speakers of your laptop or computer.
To remedy the situation, select the “Digital Audio (HDMI)” item in the same window, and then click on the “Default” function.
Now, opposite the “Digital Audio (HDMI)” section, you will see the same green icon that you saw initially before the “Speakers” item. This means that the sound will already pass through the cable to the TV.
For the changes to take effect, you should select the “OK” button and close the window.

If these manipulations did not return sound, the reason may be different.

Configuring Windows playback devices

Usually, when in Windows 10, 8 or Windows 7 you connect a TV or separate monitor via HDMI to a laptop, the sound will automatically start playing on it. However, there are exceptions where the playback device does not automatically change and remains the same. Here it is worth trying to check if it is possible to manually select on what the audio will be played.

Most likely, these three steps will be enough to solve the problem. However, it may turn out that there is nothing similar to HDMI Audio in the list of playback devices (even if you right-click on an empty place in the list and enable the display of hidden and disabled devices), then the following solutions may help.

Installing Drivers for HDMI Audio

It is possible that you do not have drivers for audio output via HDMI installed, although the video card drivers are installed (this can be if you manually asked which components to install when installing the drivers).

To check if this is the case, go to the Windows Device Manager (in all OS versions, you can press the Win + R keys on the keyboard and enter devmgmt.msc, and in Windows 10 also from the right-click menu on the "Start" button) and open the section "Sound, game and video devices". Further steps:

If there is only your sound card in the list, then the way to solve the problem will be as follows:

Note: if for one reason or another the drivers are not installed, it may be due to some kind of malfunction of the current drivers (and the sound problem is explained by the same). In this situation, you can try to completely remove the video card drivers and then reinstall them.

If the sound from the laptop via HDMI still does not play on the TV

If both methods did not help, while the desired item is exactly set in the playback devices, I recommend paying attention to:

Once again, check your TV settings.
If possible, try a different HDMI cable, or check if the sound will be transmitted over the same cable, but from a different device, not from the current laptop or computer.
In the event that an adapter or adapter to HDMI is used to connect via HDMI, the sound may not be able to make it work. If you are using VGA or DVI to HDMI, then definitely not. If DisplayPort is HDMI, then it should work, but on some adapters, in fact, there is no sound.

I hope you managed to solve the problem, if not - describe in detail what and how happens on a laptop or computer when you try to follow the steps from the manual. I may be able to help you.

Additional Information

The software supplied with the graphics card drivers may also have its own HDMI audio output settings for the supported displays.

And although this rarely helps, take a look at the settings for "NVIDIA Control Panel" (the item is located in the Windows Control Panel), AMD Catalyst or Intel HD Graphics.

Today, almost everyone already has large LCD TVs, which have successfully supplanted the anachronism in the form of older CRT models. Their huge advantage is not only the highest image quality, but also the ability to connect to a computer. Using a regular laptop, you can make a great media center with very little money.

That's just In principle, there is nothing difficult in this, but sometimes there are minor problems, for the elimination of which you have to spend a little time. Do not worry, as almost all problems are relatively easy to solve, and the price for the effort will be a great quality movie that you can enjoy on your home TV screen!

General information

So, to connect, you need a TV itself that supports this mode, as well as a computer or laptop, which can also be connected via the HDMI connector. Of course, the cable itself is also required. So how do you set up your TV over HDMI? To answer this question, you will have to conduct a small educational program on the most basic concepts.

Types of HDMI connectors and cables

By the way, what is it? This is a relatively new interface for high definition video and audio transmission. Its peculiarity is that it uses exclusively digital transmission of encoded data, which provides excellent picture and sound quality. It is not surprising that this interface is one of the most popular in the world today.

There are three types of standard HDMI connectors at once:

Type A. Standard, found in any modern technology.
Type C (micro HDMI) as well as Type D (mini HDMI). These connectors are familiar to all owners of modern cameras, smartphones and tablets. When scaled down, these modifications have all the advantages of their predecessors.
Type B. It differs in that it is capable of transmitting video with a resolution higher than 1080p, but so far it is rare.

Of course, among such a colorful "hotbed" of the connectors themselves, there are no less varieties of cables that can connect them:

Standard. Most often found, it can be used to transfer video with a resolution of up to 1080p.
High speed. You can watch 3D and other ultra high definition formats.
Standard / Ethernet. Supports not only the transmission of audio and video, but can also be used to connect to a local network. It is rare, however, as are the devices that support such a possibility. In any case, connecting a computer via HDMI to a network in our country is almost impossible to see.
High speed / Ethernet. All the same that was said in relation to the above modification, only occurs even less often and supports all high-definition video formats.
Automotive. As the name implies, it is used to connect devices that support this interface in cars.

Choosing a cable

Newbies usually have difficulties not only with how to connect a computer to a TV via HDMI, but also with the question of choosing the right cable. What you can not hear in stores! And about oxygen-free copper, and about gold-plated contacts! Some of these stories are relatively true, but they should not be believed.

So, remember one simple rule: if you are not going to watch movies in 3D on your TV, and the cable length in your case does not exceed 1.5-2 meters, you can take any model, even a Chinese one. In this segment, there is no difference between a cable for six thousand and 200 rubles. If you need 3D, then you should choose a cable of specification not lower than HDMI 1.4. In the event that there is none, you will not be able to watch a three-dimensional film through HDMI, since the cable simply cannot cope with such a volume of transmitted information.

However, even then, you should not run to the store for a cable, paying 500 or more (!) Dollars for it. Any cord of the required specification will be sufficient. Forget about the myths about "better signal path" and other nonsense. The specificity of digital transmission is that it either exists or it does not exist at all. Simply put, if the cable is capable of transmitting a signal, then it will transmit it in any case, and the quality of the image and sound will not be affected in any way. But when the computer stubbornly does not see the TV via HDMI, it makes sense to replace the cable. It may turn out that it was manufactured in violation of technology.

And now a few words about where the connectors are.

If we talk about the TV, then most often they can be found on its rear panel. However, in the latest models, HDMI connectors are often located on the side wall. Computers are easier. All necessary inputs are on the video card. If we are talking about a laptop, then in the standard case the desired input is located close to the USB 3.0 connector. Before connecting a laptop via HDMI, it does not hurt to look again at the instructions for it. It will also not be superfluous to visit the manufacturer's website, where you can familiarize yourself in detail with all the specifications that this device uses.

Connection

So how do you connect your computer to your TV via HDMI? Everything is very simple here. Connect the plug to the connector on the TV, and then insert the other end into a similar port on the computer's video card. Attention! Both devices must be turned off at this moment, otherwise there is a possibility of their breakdown!

Here's how to connect your computer to your TV via HDMI. If only one TV is connected to the computer, then everything should work right after turning them on. But if you need it in tandem with a monitor, then numerous and varied problems are possible, the occurrence of which is associated with several factors at once.

Connection problems

So, at first, you may find that all the icons and controls on the TV screen are stretched or warped. This is due to the wrong resolution. As a rule, modern operating systems set the appropriate value automatically, but this is not always the case.

To adjust the resolution, you need to right-click on any free space on the desktop, and then select the "Screen resolution" item in the context menu. Keep in mind: it is better to set the recommended values, as otherwise no one can guarantee good image quality. This applies to both the maximum and minimum values.

In addition, it does not hurt to click on the "Additional parameters" button, and then go to the "Monitor" tab. There you should click on the drop-down list "Screen refresh rate". You need to make sure that under this item is checked "Hide values that may harm your hardware."

Important! All of the above applies especially to laptops, in which damage to the screen will lead to the replacement of the entire laptop assembly. Only after you make sure that all the parameters are in full compliance, you can connect the laptop to the TV via HDMI.

The minimum suitable value is 60 Hz. However, the more the better. Of course, the color quality needs to be set to 32 bits. If after pressing the "OK" button the system does not work in normal mode, just wait 15 seconds, after which everything will return to the default settings.

Configuring the connection of multiple displays

If not only a TV, but also a monitor is connected to the system unit, the system will consider all devices as displays. The specific type of equipment in this case is completely irrelevant. Windows 7/8 has two main modes for this case: duplication and cloning. You can choose between them in the same dialog box in which you set the required display resolution.

Duplicating screen

As you might guess from the name alone, you will see two of your desktops in front of you on all connected displays. Important! Alas, standard Windows tools (and Windows 8 are no exception) do not allow you to set your own value for each monitor. Imagine what the picture would look like on a large TV and an old 4: 3 monitor!

Simply put, for comfortable use of this mode, you will have to use devices with the same resolution, since otherwise some kind of display can be turned off altogether. Since we are talking about connecting a TV, this option is still unlikely. However, you can simply pair a widescreen monitor with your TV. In this case, it will be possible to experimentally find the most suitable resolution, and there will be no annoying black bars on the sides of the desktop on the computer.

Here's how to connect a computer via HDMI using this mode.

Expanding the screen

This method is much more interesting. In this case, the TV can be made one work table, and the laptop or computer monitor - the second. Simply put, with the mouse it will be possible to select the currently active monitor on which the application will be launched.

The OS will automatically number the displays, and you can familiarize yourself with their serial numbers in the same section "Screen Resolution". If you overdid it with the number of TVs and monitors, and therefore no longer understand which one is which, just click on the "Define" button, after which the devices will be sorted in order, and the currently active monitor (or TV) will be highlighted.

Manual distribution

In the event that you do not like the order of the automatic distribution of display numbers, you can simply grab them with the mouse and put them in the right place. So, it is preferable to put the TV in the front rows, since in this case it will be much more convenient to display content on it. After all this, you can click on "Apply", after which the desktop will be extended to multiple monitors. You can set the priority using the Set as Primary button.

Roughly speaking, the monitor you select will have a Start button, and all other connected displays will be considered slave by default. As practice shows, it is not very reasonable to set the TV as the main monitor. Of course, except for those cases when it will "officially" replace your work computer monitor.

Other options

If you have installed control programs for your video card (NVidia, AMD), then the connection via HDMI can be done in the ways that their developers offer. For example, in the first case, you need to right-click on an empty space on the desktop, and then select the "NVidia Control Panel" item in the pop-up context menu. Go to the "Display" section, make the settings you are interested in. AMD programs are managed in a similar way. In general, all the configuration steps are similar to what we described above, so it will not be difficult to deal with them.

How to output audio to TV via HDMI

But what about sound over HDMI? Keep in mind that HDMI cables are very functional. Through it, not only the image is transmitted, but also the sound. Many novice users completely forget about this, and therefore spend a lot of time trying to fix "problems" that actually do not exist. For the sound to be transmitted correctly, you must have the most up-to-date drivers installed on your video card. Of course, all the same applies to drivers for sound output devices (the Realtek core integrated into the motherboard or a discrete audio card).

Let's find out how to set up audio over HDMI. To understand whether you have installed the sound output module through it, you need to open the "Device Manager". It's easy to open it. Right-click on "My Computer", select "Properties" in the context menu, and in the dialog box that opens, in the leftmost part of it, click on the desired item. A new working window will open, in which you need to find the section "Sound, game and video devices". It should contain a string like High Definition Audio that indicates support for digital quality audio playback.

Next, go to the "Control Panel" (search through the "Start" button), select the "Sound" item there. It should also have something similar to "HDMI Device". If everything is in order, turn off the computer, connect the TV, and boot the system again. The device should change its status to "Ready". It is necessary to click on it with the right mouse button, and then select the "Use as default" option in the context menu that opens.

Note!

Alas, but not on all models, sound can be transmitted to the TV via HDMI in principle, since this is due to the characteristics of the connectors. As a rule, such abilities should in any case be possessed by the first connector, which is specially designed for connecting computers, laptops and other reproducing equipment. In addition, it does not hurt to delve deeply into the TV settings. There you can often find a lot of useful things - setting the sound output, for example. However, connecting a TV via HDMI largely depends on the manufacturer and the model of the device. Remember this. Therefore, it does not hurt to read the instructions once again.

Everything, after that, the audio should go through HDMI. To be sure, reboot the entire system one more time, and then start enjoying movies in high definition, transferred from your computer or laptop. This is how audio is transmitted over HDMI.

Don't forget about the remote control!

It so happens that you have already tried all the methods, but the image stubbornly refuses to appear on the TV screen. Why is there no HDMI signal? In this case, it doesn't hurt to take a closer look at the remote control from your TV. There probably is a small Source button with which you can select the signal source.

Click on it, and then in the selection menu that appears, activate the HDMI port to which you already have a computer connected. Most likely, after such a simple action, everything will work fine. Here's how to connect your TV via HDMI.

And again about the problems

Alas, Windows wouldn't be itself if it were that simple. As a rule, many users face problems associated with duplicating images from a PC monitor to a TV screen. So, very often people complain that they cannot display the image on TB, if they do not make it the main monitor. As you can understand, this is not advisable in all cases.

Typically, the TV is used as a media player, and a regular monitor is used for work. If it is not active, you will not be able to fully work or watch movies normally. To the greatest regret, the creators of "Windows" have once again "lagged behind the times", and therefore there are simply no standard tools for normal configuration management with multiple monitors. We have to look for third-party alternatives.

The most powerful and flexible program of this type is the excellent Actual Multiple Monitors, which we'll talk about now. The program is paid, which is important for our region, but its capabilities are worth the stated price. Of course, there are a number of completely free utilities, but not always their capabilities can be compared with those for the program described below.

Actual Multiple Monitors - TV connection assistant

Of course, when creating this utility, the developers were unlikely to focus solely on connecting a TV via HDMI, but the program really simplifies its use when connected to an existing computer / monitor pair.

Unlike standard utilities, this application can make the desktop on a computer monitor and TV absolutely identical, but at the same time, you can easily set a different resolution on each of them! This is the ideal solution for those users who are quite satisfied with the old 4: 3 monitor, but would like to use a TV as a second display.

But that's not all! You can easily determine which application windows will be displayed where. Simply put, you can only display the window of the player you are using on the TV screen. Agree that this option is extremely convenient and useful! And one more pleasant circumstance. The application allows you to use a separate desktop picture for each monitor, which will surely be appreciated by all aesthetes. The program is paid, costs around $ 40, but it works out its cost in full.

How to connect two TVs if the video card has only one HDMI connector?

If you have the opportunity to connect two TVs to the system at once, one of which will be used for its intended purpose, and the other you will work with, then this is great ... But most modern video cards only have one HDMI connector. How to be in this case?

This problem can be solved in two ways. In the first case, you will need to find a DVI / HDMI adapter. Connect it to the analog output of the video card, and then use a cable to connect the system unit to the TV. However, if you are using an old monitor that connects to the system unit only through the analog connector, you will not have such problems at all. Important! Through such an adapter, sound is not transmitted to the TV via HDMI, and therefore the issue with acoustics will have to be resolved separately.

The problem is that the quality of the signal that is output to it is not too high. What if you have a high-quality monitor and TV that you would like to connect through a normal interface? In this case, you will need to buy a so-called HDMI splitter, which allows you to connect several devices at once to one output.

Important! As with cable, don't go for the most expensive of its kind. In stores you can see models for 500 dollars, but practice clearly shows that they have no significant advantages over the “Chinese” for 300 rubles. An exception should be made only for cases when you plan to watch "heavy" 3D-video. If this is really the case, you will have to buy a more expensive model, since cheap modifications rarely support such a signal density.

Finally

Here's how to connect your computer to your TV via HDMI. There is nothing difficult in this, you just need to be a little more careful. Once again, we warn you - all devices must be turned off at the time of connection! Burnout of ports is not uncommon if this instruction was ignored!

This unfortunate circumstance is connected with the fact that this cable is actually under rather high voltage. Surely everyone knows the stories about flash drives that caused USB ports to burn. And this despite the fact that the voltage on the ports is negligible (in comparison with HDMI)!

Have you decided to watch the downloaded film not on a small screen of monitors, but on a large television? Then an HDMI cable will come in handy, thanks to which the picture can be broadcast on the big screen, and the sound - in good and powerful speakers.

However, when connected, you can periodically notice that the picture is being transmitted, but the sound comes only through the computer speakers. What if there is no sound through HDMI cable on TV?

Correct connection

First, you need to check if you installed everything correctly. It often happens that the sound does not go through HDMI to the TV because you have chosen the wrong cable or the wrong ports. The following errors often occur:

Inappropriate ports were used by mistake

The cable is not at all the same

Usually, they write on the devices why certain holes are installed in them. Therefore, in this case, it remains only to wish to be more attentive to such things.

When it comes to cables, VGA does not transmit audio at all.

Setting up your computer

If you did everything correctly, but the sound on the TV via HDMI does not work, it is worth trying to check if the computer considers the TV to be a system for sound reproduction. To do this, go to the "Control Panel" through the "Start" menu, find "Hardware and Sound" there and open the "Playback" tab in the "Sound" window. If you did not find anything there, the list is empty, then right-click the menu and enable "Show disabled devices" and "Show deleted devices".

After that, your TV model should appear in the list. Click on it and disconnect the rest of the devices. This should fix the issue of HDMI TV audio not working.

If this method did not help

If you have done everything described above, but there is no sound on the TV via HDMI, you should try to check the functionality of the wire itself or the TV. Updating the sound system drivers will also help, which you can do on the official websites of the companies.

Hopefully we have helped you understand how to transfer audio through an HDMI cable.

Many users who are trying to connect a TV to a computer or laptop ask what to do if there is no sound to the TV via HDMI. Unfortunately, this problem is so common that questions related to it are asked almost every day. In this article, we'll show you how you can fix this problem.

So, first, make sure your laptop or image is transferring normally. You also need to check the sound on the TV, for this just turn up the volume with the remote control.

After that, open the "Control Panel" and find the "Hardware and Sound" section there. This section has a subsection called "Sound". Here we need to open it.

If you cannot find the subsection "Sound", then you can use the search in. Just enter "sound" in the search box and the operating system will prompt you to open this subsection of the "Control Panel".

After opening the subsection "Sound" you will see a small window with four tabs. We are only interested in the first tab, which is called "Playback". This displays a list of audio devices to which audio can be transmitted. If you have, then most likely in the "Sound" window there will be a green mark opposite the item "Speakers".

This means that audio is sent to your computer (or laptop) speakers instead of being sent over HDMI to your TV. In order to correct this situation, you need to select the "Digital Audio ()" item in the "Sound" window and click on the "Default" button.

After that, a green mark should appear in front of the “Digital Audio (HDMI)” item, which means that now the sound will be transmitted to the HDMI output. To save the settings, close the "Sound" window by clicking on the "Ok" button.
