MKV is a type of video format usually associated with high quality. MKV is not a video format per se, but rather a container that stores video information with a codec, next to audio, with another codec.

Why is there no sound on my Windows 10 computer?
Note: if the sound disappears after simply installing updates in Windows 10, then try going to the device manager (via right-click on Start), select your sound card in sound devices, right-click on it, and then go to the “Driver” tab click "Rollback".

General aspects
Before you start looking for serious faults, you should go through the obvious points:
- we check whether the sound is turned on on the laptop, speakers, using hot buttons on the keyboard;
- update and install drivers.
Quite often, the malfunction is superficial and relates to the entire system rather than specifically to the browser. In this case, the device does not reproduce sound at all, and not exclusively on the Internet. If everything works, but there is no sound, and we understand for sure that it has disappeared online, we look for the reason in the browser.
Listening with headphones
An interesting moment may await users who like to watch or listen to music on headphones. In general, the sound in this case will be quieter than when played through speakers or external speakers. This point must be taken into account when choosing headphones. If you are faced with exactly this situation, then you can increase the volume to maximum by selecting maximum volume in the player on the website, in Windows itself, and directly on the headphones. In general, a useful tip that should be applied regardless of what music is played through is to adjust the volume in one place, for example, only in the system tray in the lower right corner of the desktop. In this case, you can avoid further searches to find out exactly where the sound was turned down. In addition, you can adjust the volume using the buttons on the keyboard, which is also quite convenient. All manufacturers have their own hotkeys. They only work if a licensed OS is installed and there is a special program for this. Pirated versions of the OS may not have this function, and in general I do not recommend using them.
If the sound disappears when you connect headphones to your laptop, you need to look at the settings; sometimes the system does not automatically switch to the audio output. Switching is carried out in “playback devices”, which can be opened with RMB on the volume icon.
More serious reasons
So, you have checked and double-checked everything, made sure that the cable is intact and that your audio equipment is in good working order. Still no sound? Well, you'll have to dig deeper.
Most often (almost always) the drivers are to blame for the absence of a sound signal. Of course, physical malfunctions of the hardware also happen, but this happens very rarely. Considering that in most cases our users use motherboards with integrated audio controllers, when the latter fail, the entire motherboard often “falls”, so it’s hard not to notice.
You don't have codecs
The lack of necessary codecs is also a very common reason for the lack of sound when watching a video. In this case, sound is heard when the system starts, but when watching a video, the sound is distorted or absent altogether.
In case you don't know, a codec is a program that allows you to convert certain data or signals. In a sense, the codec allows you to play sound when watching some video formats. If you don’t have a codec on your PC that matches the extension of your video files, then there will be no sound in them.
In such a situation, K-LiteCodecPack will help you. This is a collection of all the codecs needed by the average user. Downloading the assembly is much more convenient than searching for them separately.
How to solve problems
Uninstall and reinstall the player
The first thing we're going to do is try to resolve possible problems that you might have with Windows 10 Player. Like all universal apps, it can get corrupted over time or with an update.
Therefore, the first thing we must do is try to repair the installation of the application. To do this, we will open the Windows 10 configuration menu, go to the applications section, find it and open the additional application options.
Once here, we will select the "Reset" option so that all data returns to normal.
If this does not work, we can completely remove the application from our Windows 10 and install it again from the Microsoft Store.

Download and install codecs from the Microsoft Store
The problem may be that the problems are caused by not having the proper codecs installed on your computer. Unfortunately, Movies and TV are not compatible with codec packs or classic Windows codecs, but we must install them separately from the Microsoft Store.
We can easily find codecs from the Windows 10 store and install them. Most of them are free, although fees may apply, so we must be careful. In any case, in general, when there is a problem with a codec, the player will tell us about it and provide a link to download it (for example, when trying to open HEIC), so if Movies & TV doesn't tell us anything, it's probably not codec problem.
It's no use installing a codec pack, they don't work with this player.
Windows 10 audio repair
Windows 10 has many audio options. If we change them without thinking, some configurations may cause some conflicts. And so we must let Windows restore the operating system's audio.
To do this we must open the Windows 10 configuration menu and go to System > Sound. There we will find the main Windows sound options and a button that will allow us to launch the troubleshooter. We finish it to the end and voila, there should be no more problems with sound in Windows.
Of course, we must make sure that the selected sound card is the one we are listening to. If we have headphones connected and they are selected, this may be the reason why the sound cannot be heard.
Disable exclusive sound card mode
Another option that doesn't play well with Windows 10 Player is Exclusive Mode . This mode allows you to use apps (especially UWP) to control the sound card to adjust volume, control effects, and theoretically improve playback. However, far from reality, this option causes more problems than it solves.
It's easy to check if this is the problem. It will be enough, for example, to open Spotify, leave music on it in the background, and then try to open an MKV video clip in movies and on TV. We should hear an annoying noise from the speakers and all Windows audio will stop working.
To disable this feature, we must open the Windows 10 configuration menu, go to System > Sound and open device properties. In them we will go to the advanced options and here we will have to disable the exclusive mode.
We apply the changes and that's it.
Convert video to another format
Finally, perhaps the problem is with the codec itself and there is no way around this player. If so, then the last thing we need to do is convert it to another format. We can use a real-time transcoder to change it while watching, or we can use a video converter to transfer the file to another format that is more compatible.
If we don't want to lose quality, we have to make sure we choose a quality that is equal to or better than the original video.
Problems with BIOS settings
No sound when the PC is running may also be due to BIOS settings. To check and, if necessary, correct this problem, do the following:
- Restart your PC.
- During boot, press the “F1”, “F2” and “Del” keys (these are the standard keys to start the BIOS, but yours may be different).
- When you get into the BIOS, try to find an item whose title contains the word “Integrated” or “Audio”.
- Next, if this turns out to be a section, then you need to enter it, find your device and set the “Enabled” or “Auto” settings opposite it; if this is an item opposite which there is a toggle option, do the same with it.
- At the end, press “F10” to save the work done.
The instructions presented above are quite inaccurate, since there are many different versions of Windows, each of which will have separate instructions. If you wish, you can look at your BIOS version, it is usually indicated at the top of the screen, and then try to find personal instructions for it on the Internet.
If something doesn’t work out for you, leave this option for last, since the likelihood that you messed something up without going into the BIOS is extremely low.
Your computer is infected with a virus
There are a huge number of computer viruses now, and among them there are those that can in one way or another affect the sound of your PC. You can understand that a computer is infected with a virus by various additional “symptoms”, such as general system freezes, the appearance of new applications, processes or advertisements, etc. But, of course, the most reliable way is to use an antivirus.
Everyone probably knows how to use it. But it should be remembered that removing a virus does not mean solving the problem. It is quite possible that you still have to repair the damage that the virus managed to cause while it was in the system.
Checking the sound in the YouTube player
If everything is fine with the speakers and you can hear any video from the computer or music, then go to the video hosting service to the video with which the problem arose. Next, move your mouse over the player window and pay attention to the buttons at the bottom left. Among them, we are interested in the speaker. If it is crossed out, it means that the sound is muted directly in this video.
You could have done this by accident by pressing the English letter “m” on your keyboard.
To fix this, hover your mouse over the speaker and click on it. The voice acting for the video should return. Also, don't forget to adjust the sound volume using the slider.
Checking services
- Press + R.
- Command: services.msc.
- Make sure that the Windows Audio service is enabled. You can activate it manually by right-clicking, but it’s better to go to properties and make sure that the “Startup Type” line is set to “Automatic” launch.
- Apply the settings and reboot.
No sound on YouTube: main reasons
So, once again, when we were watching our favorite video, we discovered that there was no sound - no problem.
This problem can have several sources, ranging from malfunctions in your computer to errors in the service itself……….
If the problem persists, then there is probably another reason why some YouTube videos have no sound.
Now below we will look at other popular problems that may be accompanied by the fact that the sound on YouTube does not work: ⇓⇓⇓
- Sound off. You may accidentally turn off audio in or on your computer. In this case, there is no sound on all videos.
- Software incompatibility. Very often there is no sound in some videos due to the fact that an outdated Flash player or HTML is used
- Browser. You may also find that only some browsers have no sound (for example, Google Chrome, Firefox or Yandex).
Attention!
⇒
If you suddenly notice that there is no sound when downloading to YouTube, then it is advisable to use either the format.
Sound or video is jerky
Another common question is how to fix stuttering and freezing of a movie when watching online.
Here are several recipes for treating the disease:
- reload the site;
- close the browser and launch it;
- disable all programs that require the Internet, especially uTorrent;
- Perhaps the Internet is weak, you should select the video resolution below or just download the movie.
Possible incorrect sound playback is a consequence of the browser not being updated. It should be noted that the choice of browsers today is wide and it is impossible to choose the best one. There are no restrictions for installing two or three browsers. This will make it possible to find out where video or sound works better. If Opera slows down, then Chrome may well cope with the task better. It is possible that the video will not turn on in Chrome, and in Mazil there will be no nuances in performance. This is how I solved the problem with Opera when the turbo mode was turned on. For a long time the reason was unclear; I used Google Chrome to watch the video.
Using players
Many users prefer to use players that are installed on a PC. They allow you to find movies online and watch them. This is quite convenient and many people like this option. But problems with the lack of sound or its incorrect operation remain. If the speakers work but there is no sound, and it is absent only in the application, you should check the player settings. We pay attention to the sound level, see if the player’s sound is turned on in the settings of Windows 7 (or any later version). We check whether the Internet speed is sufficient for the application to work correctly. Facts show that special programs for watching online videos work worse than players built into the browser. The trend continues across all operating systems, both Windows 8 and Windows 10.
Problems with acoustic equipment
If the sound on the computer disappears for no apparent reason, you need to start by diagnosing the acoustic equipment. Check whether the speaker plugs are seated tightly in the sockets and whether there are any kinks in the cable that caused damage. In general, it is best to connect the speakers to another PC. If they work, then everything is fine with them, and the source of the problem needs to be looked for elsewhere.
At the same time, check whether the speakers themselves are turned on; it often happens that the user accidentally turns them off, for example, while wiping dust from the surface, and forgets about it. And, of course, the speakers must be connected correctly. The speakers are connected to the green connector (audio output), and the microphone is connected to the pink one. The colors of the plug and connector must also match.
If all else fails
If everything was said above, then we check the system for viruses, since the problem may lie in them. After cleaning the system, we update the driver for the audio equipment, reinstall the codecs and reinstall the browser. When deleting, you should delete it along with the settings and install it completely from scratch. Only in this case can you make sure that all the settings are factory settings and the actions of viruses or the user have not been loaded into the new version. If even this does not help, then we roll back the system to its factory state or completely reinstall it with the obligatory formatting of the hard drive.
Fixing a problem in the browser
There are several nuances that can affect the operation of the browser and specifically the fact that there is no sound when playing music or video. The user should know that the players on the sites work using Adobe Flash Player. This is a third party application that needs to be installed and updated. The standard reason that no sound is played when watching a movie is the absence of this program or its outdated version. To eliminate the defect, just download the necessary software from the manufacturer’s official website and install it. The installer takes up little space on your hard drive and the process will take a few minutes. An important point is that during the installation process the browser must be closed, and ideally, the functionality must be checked after a reboot.
The second reason is the old version of the browser. The developers of any browser periodically release updates, they make the program work fast, stable and comfortable. Sometimes uninstalled updates do not cause problems and you can work quite well in the old version, but there are update packages without which it is difficult to achieve correct operation. The user can also see that the sound has disappeared.
Often the sound disappears not due to any software shortcomings, but due to connected utilities or extensions. The Opera browser launches turbo mode - its task is to save traffic and speed up your work on the Internet. In general, there will be no noticeable inconvenience, but built-in players on websites stop working. If the user does not know about this influence of the extension, then he can guess for a long time and unsuccessfully what the defect is and how to get rid of it. In this situation, reinstalling the browser will not help. The program will automatically load user settings, and traffic saving mode will be enabled by default. My advice is that if the sound is turned off as a result of any actions in the browser related to setting it up or improving it, you need to cancel them and see the result. In general, before installing anything in the browser, you should read the reviews and ratings of the extension, then you should decide whether to install it or abstain.
It is worth remembering about the mute function in browsers on specific pages. If several pages are open and sound is played on them, then next to the cross to close the site on the top panel of the browser you will see a sound icon - a small speaker. When you click on it, the site will continue playing, but the sound will be muted. It happens that the icon was accidentally pressed and there is no sound.
If the sound becomes quieter when watching a video, then it is likely that it was turned down directly in the browser. The players on the site generally do not differ from a regular program installed on a PC. They have a number of settings, in particular the volume level. Check this moment.
Sometimes there is a quiet sound in the browser when watching a video, although everything is turned on at full volume. The reason in this case lies in the sound track itself, it is simply not loud enough. I recommend just searching for the movie on another site or downloading it to watch offline.
