Sound is not transmitted via HDMI on the monitor. Why is there no sound on the TV when connecting to HDMI?
If your favorite way to spend your free time is computer games or watching movies online, no doubt one day it occurred to you that the TV screen will provide you with a larger, more spectacular and more convenient picture.
Today, many people connect a TV to their computer to use it as an additional monitor. Almost all modern TVs provide this feature, so there are few problems when connecting, but they still happen.
Connection via HDMI cable
If previously a special cable with several “tulip” connectors was used to connect a TV to a computer, today its role is perfectly fulfilled by an HDMI cable, which provides the highest quality of the screen image.
The connection itself is not a problem, because HDMI connectors are available on any TV and on any computer device - a stationary system unit, laptop, etc. You just need to connect the appropriate cable connectors to them, and the job can be considered done.
Sound problems
But here sometimes troubles begin: if the image appears on the TV screen without problems, then difficulties arise with sound transmission. Or rather, there is sound, but it comes from the computer speakers, while on the TV the sound remains muted. 
Of course, you can leave everything as is, but if you want to achieve complete comfort, you need to complete the connection. First of all, make sure that the sound on your TV is actually not coming from the computer, and is not turned off. To do this, try adjusting the volume with the TV remote control.
After making sure that everything is in order, look at the volume slider on the computer - perhaps it is set to zero, and the sound does not reach the TV speakers for this very reason.
Audio Sync
As you know, in the lower right corner of the computer screen on the taskbar there is an icon for sound devices. Sometimes it is used to increase or decrease the volume or to adjust the sound. Let's use it this time too.
Right-click on the speaker icon. In the menu that opens, select "Playback Devices" and open this tab. All available audio devices should be listed there, among which the TV should be on the list.
All you have to do is select it and right-click to open the context menu, in which check the box next to the item "Use as default"
. In most cases, this is enough for the sound to be reproduced normally by the TV speakers. 
The situation is somewhat more complicated when the TV is not displayed in the audio device menu, i.e. the computer simply “does not see” its speakers. In this case, as in many others, a hard reboot can help you. Without disconnecting the HDMI cable, .
Once the reboot process is complete, open the sound menu again and make sure your TV appears in the list. If it is inactive, proceed as described above - set its status "Use as default" .
Sometimes, in order to resolve a device conflict, it is necessary to disconnect all other audio peripherals such as speakers and headphones from the computer. Otherwise, a device priority conflict occurs - the computer cannot choose which one to use to play sound. When the extra devices disappear, the situation returns to normal.
The possibility of a cable defect cannot be ruled out - if some of its connectors are oxidized, or one of the wires is broken, sound reproduction becomes impossible. In order to set up the system, you will need a fully working, tested HDMI cable.
If your computer has a video card installed NVIDIA, the sound problem may lie in its settings. These video cards have their own sound controller, the operation of which will have to be regulated through the sound menu of the player you use to play movies. 
Open the player menu and check the sound settings by checking the box next to "NVIDIA High Definition Audio". After doing this, the problem should be resolved.
Many users, not wanting to watch movies or TV shows on a small monitor, connect a laptop to a TV panel from LG, Samsung, Sony or another brand to display the image on a large screen. However, when connecting equipment using most cables, only a picture is sent to the display, whereas when using HDMI, not only video, but also an audio signal can be transmitted to the TV receiver. However, sometimes after connecting the devices, you find that there is no sound on HDMI on the TV. Such a malfunction can occur for a number of reasons, and in order to eliminate it, you must first diagnose the equipment and the configured connection.
Diagnosing and fixing the problem
If the audio signal from the PC does not come through the HDMI cable, to correct the error and output sound to the television panel, the user needs check connection for all possible errors. The problem may lie in the settings of the TV receiver or PC, an incorrectly selected playback source, missing or outdated drivers, etc.
Checking volume levels
If there is no sound coming from the TV's speakers, you need to check whether the volume on both devices is turned off. This can be done on TV using the remote control or control keys, located on the body.
On PC you will need click on the speaker icon in the tray(lower right corner on the monitor) and make sure that the slider is set to maximum. Next, you need to call up the context menu and go to “Volume Mixer”. Here you need to make sure that the sound is turned on and set to maximum for all running applications and devices.
Note! You can also check the volume level on a PC or laptop using the function keys. To do this, first press the “FN” button, and then press the volume up (usually one of the arrow keys or the F1-F12 buttons). After pressing, the user will see a slider with the volume level in the upper right corner of the screen and will be able to increase it if necessary.
Hardware problems
A problem with the cable or one of the devices is also a common reason why a PC won't transmit audio to the TV via HDMI. If the TV speakers are working properly (sound appears when you turn on TV channels), you need to check the functionality of the connector. To do this, switch the cable to another port. If the problem persists, you need to check the connector on your laptop or PC by connecting other equipment to it.
If the connectors are in order, then proceed check cable functionality. To do this, you need to connect a DVD player or digital receiver to your TV through it. This technique does not require additional setup, so the user will immediately see the picture on the screen and hear the sound in the TV speakers if the cable is working properly.
Very often, cheap Chinese HDMI cables that users buy in order to save money turn out to be faulty. They either cannot immediately reproduce the transmitted content, or the image (or sound) regularly disappears. To avoid such problems, you should buy reliable branded cables.
Important! If the sound was working properly, but suddenly disappeared, this indicates that the cable may have been broken or damaged by pets. You need to carefully inspect it for external damage.
Transferring sound from a PC to a TV panel will be an impossible task when using some adapters. So, if DVI-HDMI or VGA-HDMI were used when connecting the computer to the TV receiver, the audio signal will not pass through. A similar problem is also possible when using inexpensive DisplayPort-HDMI adapters, which also do not have the technical capabilities to transmit sound.
Selecting playback source
When you connect an external audio device to your PC, Windows automatically detects the new hardware and transfers audio to it. In some cases this does not happen and the user needs to manually set audio signal transmission to connected equipment. To do this, click on the speaker icon in the tray and select “Playback devices”.
Note! On a Windows 10 PC, you need to select “Sounds”, then “Playback”.
A window will appear in front of the user with all available audio output equipment. You need to find the TV icon and set it as default device. As a result, sound should appear in the speakers of the television receiver.
TV Display Settings
If the television panel does not appear in the list of devices for sound output, you need to right-click in an empty space of the window and set labels to reflect disconnected and disabled devices. As a result, the TV should appear in the list of equipment. If this does not happen, you need to restart the PC with the television panel connected. After the computer starts again, you should re-open the playback devices tab. The TV should now be selectable. If after rebooting the PC still does not see the connected TV receiver, you need to check whether the drivers for the equipment are installed.
Driver problem
Another popular problem, as a result of which sound from a laptop or PC is not output to the speakers of the TV receiver, is uninstalled hardware drivers. To verify this, you need to open the “Device Manager” (for Windows 8 and 10 – through the context menu of the “Start” button, for Windows 7 – through the context menu of the “My Computer” icon).
Advice! On any version of the OS, including Windows XP, you can use the “Win+R” key combination to open the “Run” command and enter “devmgmt.msc”.
In Device Manager, you need to open the “View” section, and then select the display of hidden devices in the drop-down list. Next, open “Sound, game and video devices”. In addition to the audio card, the list should display one of the devices such as NVidia High Definition Audio, AMD High Definition Audio or another, with the name HDMI included - this is the component used to output audio via HDMI. If it is disabled, need to be turned on it through the context menu.
If the required component is not in the list of audio devices, you need to install drivers so that the required utility is detected by the computer and starts working. To do this, go to the website of the video card manufacturer and, in accordance with the model, download the latest versions of drivers.
Note! Driver installation should be done manually. For example, for GeForce graphics cards manufactured by NVidia, during installation you need to make sure that the “HD Audio Driver” is present, which is responsible for transmitting the audio signal via HDMI. On video cards from other manufacturers, this driver is called differently.
However, if the drivers are not installed for any reason, you must completely remove the video card software and the hardware itself from the system and then install it again. To download these auxiliary utilities, the user will need an Internet connection, which can be configured using the services of providers such as Rostelecom, MTS, TTK and others.
NVIDIA controller
If a graphics adapter from NVidia is installed on a laptop or PC, in order to transmit an audio signal to the TV, the user will need access the built-in audio controller. To work with it, you need to launch the video player through which you usually watch movies or TV series, and in the sound settings, enable Nvidia High Definition Audio as the default device.
Other faults
Usually, along with sound drivers, software is installed on the computer, which has its own utilities for outputting sound via HDMI. Such programs include Intel HD Graphics, AMD Catalyst, NVidia Control Panel, etc. In rare cases, this circumstance may cause the absence of an audio signal on the TV receiver when connected via HDMI. To correct the situation, you need to open such a utility and configure the sound settings correctly.
Features of settings on different versions of Windows
Setting up sound on Windows OS of different versions is the same, but it is possible differences in the locations of the required sections. For example, on Windows 7, “Playback devices” are available from the context menu of the speaker tray icon. And to open the same tab on Windows 8 or 10, you must first click on “Sounds” and only then on the “Playback” tab. The main nuances of the location of certain sections were discussed in the relevant paragraphs of the above material.
So, if the user decides to connect a computer via HDMI to his Philips, Toshiba, Panasonic or other brand of TV, but after connecting he finds that only the image is transmitted and the sound does not work, then he first needs to diagnose possible software problems, and then identify problems in cable or connectors. Lastly, you should check the equipment itself for serviceability, and, if a breakdown is detected, contact professional technicians at the service center, excluding repairs on your own, so as not to aggravate the problem.

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 will talk about how you can solve this problem.
So, first, make sure that your laptop or image is transmitted normally. You also need to check the sound on the TV; to do this, just turn up the volume using the remote control.
After that, open the “Control Panel” and find the “Hardware and Sound” section there. This section has a subsection called “Sound”. This is what we need to open.
If you cannot find the “Sound” subsection, then you can use the search in. Just enter “sound” in the search bar and the operating system itself will prompt you to open this subsection of the “Control Panel”.
After opening the “Sound” subsection, a small window with four tabs will appear in front of you. 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 “Speakers” item.
This means that the audio is sent to your computer (or laptop) speakers instead of being sent via 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 this, a green mark should appear opposite the “Digital Audio (HDMI)” item, which means that the sound will now be transmitted to the HDMI output. In order to save the settings, close the “Sound” window by clicking on the “Ok” button.
Today, almost everyone has large LCD TVs, which have successfully replaced the anachronism in the form of old 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 an excellent media center for very little money.
It’s just that, in principle, there is nothing complicated about this, but sometimes there are minor problems that require a little time to resolve. No need to worry, as almost all problems can be solved relatively easily, and the reward for your efforts will be a movie in excellent quality 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 an HDMI connector. Of course, you also need the cable itself. So how do you set up your TV via 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 this? This is a relatively new interface for transmitting high-definition video and audio. Its peculiarity is that it uses exclusively digital transmission of encoded data, which ensures 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:
- 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. Being smaller, 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 is still rare.
Of course, among such a colorful “hotbed” of connectors themselves, no less varieties of cables have appeared that can connect them:
- Standard. It is most common and can be used to transmit video with a resolution of up to 1080p.
- High speed. You can watch 3D and other ultra-high definition formats.
- Standard/Ethernet. It not only supports audio and video transmission, but can also be used to connect to a local network. Rare, however, as are devices that support this feature. In any case, connecting a computer via HDMI to a network is almost impossible to see in our country.
- High Speed/Ethernet. Everything is the same as was said regarding the modification described above, only it is even less common and supports all high-definition video formats.
- Automotive. As the name suggests, it is used to connect devices that support this interface in cars.
Choosing a cable
Beginners usually have difficulties not only with how to connect a computer to a TV via HDMI, but also with the issue of choosing the right cable. What you don't hear in stores! And about oxygen-free copper and gold-plated contacts! Some of these stories are relatively true, but you definitely shouldn’t believe everything.
So, remember one simple rule: if you are not going to watch 3D movies on 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 that costs six thousand and one that costs 200 rubles. If you need 3D, then you should choose a cable with a specification of at least HDMI 1.4. In the case where there is none, you will not be able to watch a three-dimensional movie via HDMI, since the cable simply cannot cope with such a volume of transmitted information.
However, even then you shouldn’t run to the store to buy a cable, paying 500 or more (!) dollars for it. Any cord of the required specification will be sufficient. Forget about the myths that talk about “better signal transmission” and other nonsense. The specificity of digital transmission is that it either exists or it doesn’t 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 suffer in any way. But when the computer stubbornly does not see the TV via HDMI, it still makes sense to replace the cable. It may happen that it was manufactured in violation of technology.
And now a few words about where the connectors are.
If we talk about a TV, then most often they can be found on its back panel. However, in the latest models, HDMI connectors are often located on the side wall. It's easier with computers. 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 your laptop via HDMI, it won’t hurt to look at the instructions for it again. It would also be a good idea to visit the manufacturer’s website, where you can familiarize yourself in detail with all the specifications that this device uses.
Connection
So how to 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 its other end into a similar port on the computer’s video card. Attention! Both devices must be turned off at this moment, otherwise they are likely to break!
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 immediately after they are turned on. But if you need it in conjunction 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 your TV screen appear stretched or warped. This is due to incorrect 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 “Screen Resolution” from the context menu. Keep in mind: it is better to set the recommended values, since otherwise no one can guarantee good image quality. This applies to both maximum and minimum values.
In addition, it doesn’t hurt to click on the “Advanced Settings” button, and then go to the “Monitor” tab. There you should click on the “Screen refresh rate” drop-down list. You need to make sure that under this item there is a checkbox “Hide values that may harm your equipment.”
Important! All of the above especially applies 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 parameters fully comply, 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 rendering quality must be set to 32 bits. If after clicking the "OK" button the system does not work normally, just wait 15 seconds, after which everything will return to the default settings.
Setting up 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 to be displays. The specific type of equipment in this case is completely unimportant. 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.
Screen mirroring
As you can guess from the name alone, your two desktops will be displayed in front of you on all connected displays. Important! Alas, standard Windows tools (and Windows 8 is no exception) do not allow you to set your own value for each monitor. Imagine what the image will look like on a large TV and an old 4:3 monitor!
Simply put, to use this mode comfortably, you will have to use devices with the same resolution, since otherwise some 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 your computer via HDMI using this mode.
Expanding the screen
This method is much more interesting. In this case, the TV can be made into one desktop, and the laptop or computer monitor can be made into a second one. Simply put, you can use your mouse to select the currently active monitor on which the application will run.
The OS will automatically number the displays, and you can see their serial numbers in the same “Screen resolution” section. If you have gone too far with the number of TVs and monitors, and therefore no longer understand which one is which, just click on the “Detect” button, after which the devices will be sorted in order, and the currently active monitor (or TV) will be highlighted.
Manual distribution
If you don’t like the order of 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 place 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 expanded to multiple monitors. Using the “Make Primary” button you can set the priority.
Roughly speaking, the monitor you select will have a Start button, and all other connected displays will be considered slaves by default. As practice shows, setting the TV as the main monitor is not very wise. Of course, except for those cases when it will “officially” replace your work computer monitor.
Other options
If you installed control programs for your video card (NVidia, AMD), then connecting via HDMI can be done using the methods suggested by their developers. For example, in the first case, you need to right-click on a free space on the desktop, and then select “NVidia Control Panel” from the context menu that appears. Go to the “Display” section and make the settings you are interested in. AMD programs are managed in a similar way. In general, all setup steps are similar to what we described above, so it won’t be difficult to figure them out.
How to output sound to TV via HDMI
What about sound via HDMI? Don't forget that an HDMI cable is a very functional thing. Not only images are transmitted through it, but also sound. Many novice users completely forget about this, and therefore spend a lot of time trying to fix “problems” that actually don’t exist. For sound to be transmitted correctly, you must have the most current versions of drivers installed on your video card. Of course, the same applies to drivers for audio output devices (the Realtek core integrated into the motherboard or a discrete audio card).
Let's learn how to set up sound via HDMI. To understand whether you have a sound output module installed through it, you need to open “Device Manager”. It's easy to open. Right-click on “My Computer”, select “Properties” in the context menu, and in the dialog box that opens, on the far left side, click on the desired item. A new working window will open in which you need to find the “Sound, game and video devices” section. It should contain a line like High Definition Audio, which 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”. You need to right-click on it, and then select the “Use as default” option in the context menu that opens.
Pay attention!
Alas, not all models can transmit sound to a TV via HDMI in principle, as this is due to the characteristics of the connectors. As a rule, the first connector, which is specifically designed for connecting computers, laptops and other reproducing equipment, should in any case have such capabilities. In addition, it doesn’t hurt to dig deep into the TV settings. There you can often find a lot of useful things - setting up sound output, for example. However, connecting a TV via HDMI largely depends on the manufacturer and model of the device. Remember this. Therefore, it won’t hurt to read the instructions again.
That's it, after this the audio must go via HDMI. To be sure, reboot the entire system again, and then start enjoying high-definition movies streamed from your computer or laptop. Here's how audio is transmitted over HDMI.
Don't forget about the remote control!
It happens that you have already tried all the methods, but the image stubbornly refuses to appear on the TV screen. Why is there no signal via HDMI? In this case, it won’t hurt to take a closer look at the remote control for your TV. There is probably a small Source button there, with which you can select the signal source.
Click on it, then in the selection menu that appears, activate the HDMI port to which your computer is already connected. Most likely, after such a simple action, everything will work perfectly. Here's how to connect your TV via HDMI.
And again about the problems
Alas, Windows would not be itself if everything was so simple. As a rule, many users encounter problems associated with duplicating images from a PC monitor to a TV screen. So, very often people complain that they are unable to display an image on a TV unless they make it their main monitor. As you can understand, this is not advisable in all cases.
As a rule, a 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 work fully or watch movies normally. Unfortunately, the creators of Windows are once again “behind the times,” and therefore there are simply no standard tools for properly managing a configuration 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 application, which we will 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 their capabilities are not always comparable to those of the program described below.
Actual Multiple Monitors - assistant in connecting a TV
Of course, when creating this utility, the developers were unlikely to focus exclusively on connecting a TV via HDMI, but the program really simplifies its use when connecting 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 an ideal solution for those users who are quite happy with the old 4:3 monitor, but who 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 image for each monitor, which will certainly be appreciated by all aesthetes. The program is paid, it costs around 40 dollars, but it works out its cost in full.
How to connect two TVs if the video card only has 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 second you will work on, then this is great... But most modern video cards only have one HDMI connector. What to do 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 is connected to the system unit only via an 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 very high. What to do if you have a high-quality monitor and TV that you would like to connect via a normal interface? In this case, you will need to buy a so-called HDMI splitter, which allows you to connect several devices to one output at once.
Important! As with cables, don't try to buy the most expensive products of their kind. In stores you can see models costing $500, but practice clearly shows that they do not have any significant advantages over the “Chinese” ones for 300 rubles. An exception should be made only for cases when you plan to view “heavy” 3D video. If this is really the case, you will have to buy a more expensive model, since cheap modifications rarely support such signal density.
In conclusion
Here's how to connect your computer to your TV via HDMI. There is nothing complicated about this, you just need to be a little more careful. We warn you once again - all devices must be turned off at the time of connection! It is not uncommon for ports to burn out if this instruction is ignored!
This unfortunate circumstance is due to the fact that this cable is actually under quite high voltage. Surely everyone knows stories about flash drives that caused USB ports to burn. And this despite the fact that the voltage on the ports is negligible (compared to HDMI)!
