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.

Solution 3. Check the Audio Driver

Audio drivers are a type of computer file that allows other programs to recognize and appropriately interact with an audio device, like speakers and headphones. Check to make sure that your audio drivers aren't outdated or malfunctioning, as this could also be the cause of your MKV videos not producing sound. Here are a few things you can try.

1. Update Your Audio Driver

This is the most direct way of updating your audio drivers without the use of any third-party programs.

Step 1: Type in the taskbar search box, "Device Manager," and then select it from the search results.

Step 2: Click on the arrow beside "Sound, video and game controllers" to expand the list and then click on the "Delete the driver software for this device" checkbox to uninstall.

Step 5: Select Restart from the Power menu to initiate the restart process. Restarting will automatically prompt your computer to reinstall your audio driver.

Solution 6. Use the Windows Troubleshooter

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.

Step 3: Choose "Troubleshoot" from the menu.

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.
