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 Wondershare Repairit" section of our guide.
- You don't have another media player: We suggest downloading the excellent free media player, VLC.
If you use third-party media players like VLC, PotPlayer, and GOM player, they should 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 3: Scroll down until you find your media player. Select it and click on "Uninstall." Agree to any prompts about fully uninstalling the media player and wait for it to finish.
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. Fix MKV No Sound Caused by Video Itself Corruption

One of the cool new additions introduced in Windows 10 is the built-in troubleshooter, including an audio troubleshooter tool. Troubleshooters help users fix many common issues they may be experiencing, including the MKV video no sound problem. What's great about the tool is that it initiates an automatic process which fixes your audio issues for you. Just follow these steps to get it done.
Step 1: Click on the Start button or tap the Windows key and select "Settings" from the menu.
Step 2: Click on "Update & Security" in the settings window.

The Troubleshoot settings "Get up and running" section has the more common problems that users experience arranged in alphabetical order and includes Internet Connections, Printer, and Windows Update. The "Find and fix other problems" section provides troubleshooting options for a more extensive range of system-related problems.
These include Bluetooth, Incoming Connections, Network Adapter, Windows Store Updater, Searching & Indexing, Video Playback, Recording Audio, and Program Compatibility Troubleshooter. With all these options and more, there isn't any reason not to give the Windows Troubleshooter a try when encountering any issue on your computer.
You can also access the audio troubleshooter by typing "Troubleshoot settings" in the taskbar's search box.
Solution 7. Change the MKV File Format
Your computer might lack the resources to play your MKV video properly or driver and codec issues, leading to MKV video playback with no sound. Whatever the cause, converting your video to a more common format like MP4 will save you many headaches.
Here's our guide on how to convert your MKV video file format to MP4 using Wondershare Uniconverter:
Step 1: Click on the triangle near "Add Files" and select "Add from Camcorder." Select your MKV video in the popup window and click "Add to List."
Step 2: Click on the triangle near "Convert all files to:" and select "Video." Pick MP4 as your desired file format.
Step 3: Click on the Edit icon next to the file resolution to enter the "Settings" window. Select the settings you prefer or pick "Small Size" to let Uniconverter select the details for you.
Step 4: Click "OK." Then click on the "Convert All" button to begin the conversion process. Once the process has ended, play your converted MKV video to make sure it now has sound during playback. Click the Convert button.
Solution 8. Repair MKV Codec Problems
Video files are ordinarily large files, but we can compress them into smaller file sizes and then decode them during playback through codecs. 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 many issues, including 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 ensure 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."
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 no sound during playback.
There are five possible reasons why MKV video files lose audio during playback.
- A problem with the MKV codec on your computer or device.
- A problematic media player who 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 were introduced to the file during conversion from one format into an MKV file.
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 your files and programs end up corrupt, restore the backup.
