No Sound With MKV Files in Windows 10

How To Solve Sound Problems With MKV Files in Windows 10

  1. What is .mkv file format?
  2. Solution 1 – Switch to a third party media player
  3. Solution 2 – Convert .mkv files to MP4
  4. Solution 3 – Run Windows 10’s built-in troubleshooter

Few months before the release of Windows 10, it was announced that Windows 10 will natively support .mkv and .flac files, and this was great news for all multimedia fans.

So, here’s what you need to know about this file format and how you can fix sound issues.

1. What is the .mkv file format?

MKV file format was created in Russia in 2002 as an open source, so anybody can use it for free of charge for personal use. In fact, .mkv became the basis for new WebM multimedia format. Despite the popular belief .mkv files are actually multimedia container formats that combine audio, video and subtitles into a single file.

This means that you can combine different audio and video file formats into a .mkv file format. MKV files also support seeking, chapters, menu, and metadata support, different audio and video streams, online streaming compatibility, subtitles and error recovery.

In addition, .mkv files support almost any audio and video format, so it’s safe to say that MKV files are here to stay.

So if .mkv files are so awesome and rich with features, why is there no sound with .mkv files on Windows 10? Apparently Movies and TV app has some problems with DTS audio that mkv files use, and this is the main reason why there’s no audio with .mkv files. This is an annoying error, but how can you fix it?

Solution 1 – Switch to a third party media player

As we mentioned, Movies and TV app doesn’t have support for DTS audio, so the only solution is to wait for official update from Microsoft, but this might take a while, depending how high this issue is on their list of priorities.

Instead you can always switch to third-party media player such as VLC, or any other. There are no issues with third-party players, so until Microsoft releases an update for Movies and TV app only solution is to use third-party multimedia player.

Even if you have other problems with .mkv files, not just sound issues, you can try with the third party player.

Solution 2 – Convert .mkv files to MP4

If the issue persists even when using a third-party media player, this could indicated that there’s something wrong with .mkv file itself. Converting it into an MP4 file could help you fix this problem.

You can use VLC to complete this task. This versatile media player can also convert Mastroska files into MP4 files.

Simply launch VLC and click on the Media menu. Select Convert/ Save and upload the problematic file to VLC. Now, you need to select the video format to use, specify the destination folder and launch the process.

Solution 3 – Run Windows 10’s built-in troubleshooter

Windows 10 also features a dedicated audio troubleshooter that could help you get back sound on .mkv files. Go to Settings > Update & Security and click on Troubleshooter. Go to ‘Get up and running’, select ‘Playing audio’ and run the troubleshooter.

Check if the problem persists.
