Matroska videos or MKV is an ingenious video file format that was created in Russia in 2002. What's so great about it is the way it combines audio, video, and subtitles in a single file and provides added functionality to boot.

Unfortunately, many have encountered a nagging issue. The MKV video no sound problem is when audio is absent during playback. Everyone's first thought is to redownload the video, but that isn't always the solution. So stop wasting your data and try out these methods instead.

Solution 1. Check the Media Player

There are several ways for an MKV video to become corrupt but here are just a couple: memory card issues, change in video format, device crash, improper transfer or download, unreliable media players, etc.

First and foremost, check that your media player isn't at fault. You can confirm this by playing other videos in the player (MKV and non-MKV files). If you have another media player installed, try the problem video there as well. Here are some scenarios that could result:

  • MKV videos played with sound in your other media player: The fault is from the first media player you used. You can switch to using your other media player to playback MKV files or follow the solution we will provide below.
  • MKV videos did not play on either media player: It could be a codec problem, or your media player cannot play MKV files. We recommend downloading and using a media player like VLC to fix this issue.
  • Only that particular MKV video did not play: This means the MKV video file is corrupt. We've provided a solution to this in the "How to Fix MKV File No Sound with Recoverit" section of our guide.
  • You don't have another media player: We suggest downloading the excellent free media player, VLC. Instructions on how to do so are in this solution, from Step 8-14.

If you use third-party media players like VLC, PotPlayer, and GOM player, then they should be able to play MKV files without taking any additional steps. This means that the likely cause for your issue is a faulty installation. You can check out how to repair corrupt MKV files further in this article, but regarding your media player, here's what you do.

Step 1: Press the "Windows" key to bring up the Windows menu. Click on the "Settings" icon.

Step 2: In Windows Settings, click on "Apps." Make sure you are on the Apps & Features tab by checking the menu on your left.

Step 4: Now download a new installation file for your third-party media player to any location you prefer.

Step 5: In the "download complete" page, tick the "Run VLC media player" box and click finish.

Step 6: Once VLC opens, try your MKV video once more to make sure your problem has been fixed.


Solution 2. Use Video Repair Software

Let's say you discover your MKV video isn't playing with sound, so you decide to try other media players, but they all have the same issue. You've done everything you can think of, from installing more codecs to updating all your drivers. Then it means your MKV video is at fault.

Whether you downloaded the MKV videos or transferred them from another device, it's always annoying to realize that you will have to get them again. Usually, that would mean re-downloading the MKV video or trying to get your hands on the device that you copied if from the first time. Depending on the situation, either could result in a lot of stress that we would all prefer to avoid.

Solution 5. Change the MKV File Format

Please note that you must be carefule when converting videos, as the operation often cause video errors, like 0xc00d5212.

Solution 6. Repair MKV Codec Problems

Video files are ordinarily large files, but through the use of codecs, we can compress them into smaller file sizes and then decode them during playback. Codecs are small pieces of code that make this possible, without which, playback would be impossible.

That's why the absence of codecs will prevent playback, while corrupt codecs will cause any number of issues, which include the MKV video no sound problem. K-Lite Codec Pack is one of, if not the most popular high-quality codec packages out there. Using it will make sure your MKV videos will be encoded and decoded correctly, removing your no sound woes.

This is what you do if your codecs are corrupt or outdated.

Step 1: Install the software. Make sure Profile 1 is selected and leave all the options in their default setting and click "Next."

Step 2: For "Additional Tasks and Options," leave the default options and click "Next." Under "Hardware Acceleration," leave the default options and click "Next."

Use the default settings

Step 3:Under "File associations," make sure to select all media players installed on your computer if you want the codecs to work with them. Or make sure you've set your primary media player to "All Video Extensions." Click "Next."

Step 4: Under "Speaker configuration," select whatever preference your computer can handle. Click "Next."

Speaker configuration setting

Step 5:The "Ready to Install" page will provide a summary of all your selections. Look through to make sure all is in order and then click "Next" to begin the installation process.

Step 6:Once the installation is complete, click "Finish" and test your MKV video to make sure there's now sound during playback.

Make sure all selections are correct

Final Reviews on MKV Video No Sound

MKV files or Matroska files were developed in Russia in 2012 by lead developer Lasse Kärkkäinen and its founder, Steve Lhomme. It was named after the Russian nesting dolls, matryoshka, for how it similarly contains multiple multimedia files.

Using the .mkv file extension, Matroska files were designed to be future proof. Unlike audio and video compression formats, MKV is a container that can combine audio, video, and subtitles in a single file, no matter what each of these encoding components was encoded in. Additionally, MKV files support several key features like:

  • Chapter, menu, and metadata.
  • Different audio and video streams.
  • Error recovery which allows the playback of corrupt files.
  • Fast seeking
  • Online streaming

Why does an MKV file have no sound?

There are five possible reasons why MKV video files lose audio during playback. They are:

  • A problem with the MKV codec on your computer or device.
  • A problematic media player which either wasn't installed properly or received damage afterward.
  • Your chosen media player is not compatible with DTS audio, which is the audio format most commonly used by MKV files.
  • The MKV file itself is corrupt, rendering a part or all of the sound unplayable.
  • Errors introduced to the file during conversion from one format into an MKV file.

How to prevent video corruption

Ever heard of the saying," Prevention is better than cure?" It's hard to argue with it after you've experienced losing valuable data or treasured videos due to irreparable damage. To protect yourself from the possibility of having to deal with corrupt MKV videos all the time, follow these tips:

  • Make sure your computer is protected from voltage spikes by a surge protector.
  • Always correctly shutdown your computer and don't abruptly turn it off while in use, especially when working on or playing files.
  • Always use the USB cable that was supplied with your devices and only buy a replacement approved by the manufacturer.
  • Make sure your antivirus software is always up to date and turned on. Scan your computer regularly.
  • Keep backups of your files in a separate location like an external hard drive, so if the video on your computer becomes corrupt, you can replace it with your backup.
  • Backup your system often, so if any of your files and programs end up corrupt, simply restore the backup.

Closing Words

It's never fun to find out that the videos you've been looking forward to watching won't play properly. It's even worse if you don't know what to do about it. Now that we've given some causes as well as solutions to MKV videos having no sound during playback, nothing will get in the way of your viewing experience again.
