Watching your favorite MKV files only to find no sound can be frustrating. This issue is common on Windows 10 but usually easy to fix. With a few simple steps, you can restore audio and enjoy your videos again.
This guide will walk you through basic to advanced solutions to fix no sound in MKV files. Each step is explained clearly to help even beginners understand.
Follow the instructions carefully, and by the end, you should have your sound working perfectly. Let’s get started with some quick checks before diving into detailed fixes.
Remember, patience is key — sometimes the solution is simpler than you think!
Quick Note: Before You Begin
- Check Your Volume: Make sure your system volume and media player volume are not muted or set too low.
- Try Different MKV Files: Test other MKV files to see if the problem is with a specific file or all MKV files.
- Use a Different Media Player: Some players may not support certain audio codecs. Try VLC Media Player or MPC-HC as alternatives.
- Update Windows: Ensure your Windows 10 is up to date with the latest updates installed.
Step 1: Check Audio Track Selection in Your Media Player
Many MKV files contain multiple audio tracks, like different languages or commentary. Sometimes the default audio track might be silent or unsupported.
- Open your MKV file in your media player.
- Look for an option called Audio or Audio Track in the player’s menu.
- Select a different audio track to see if the sound returns.
Why this helps: If the player switches to a silent or incompatible audio track, changing it manually can fix no sound issues immediately.
Step 2: Update or Change Your Media Player
Using an outdated or incompatible media player often causes audio problems with MKV files. Some players do not support certain audio codecs embedded in MKV.
- Update your current media player to the latest version.
- If updating doesn’t help, download and install a different player known for wide codec support, like VLC Media Player.
- Try playing the MKV file again with the new player.
Why this is important: VLC and MPC-HC support almost all audio and video codecs out of the box, so you can avoid codec-related sound issues.
Step 3: Install or Update Audio Codecs
Sometimes Windows 10 lacks the necessary audio codecs to decode the sound track in an MKV file.
- Download a trusted codec pack like the K-Lite Codec Pack.
- During installation, choose the default settings to ensure all common audio codecs are installed.
- Restart your computer after installation.
- Try playing the MKV file again.
Why codecs matter: Codecs are like translators between your media player and audio files. Without the right codec, the sound may not play properly.
Step 4: Convert the MKV File’s Audio Track
If the above steps don’t work, the audio track inside the MKV file might be damaged or in an unsupported format.
- Use a free video converter tool like HandBrake or FFmpeg.
- Open the MKV file in the converter.
- Choose to convert the audio track to a common format like
AACorMP3. - Save the new file and try playing it again.
Why convert? Converting the audio to a widely supported format fixes compatibility and corruption issues.
Step 5: Update Sound Drivers on Windows 10
Outdated or corrupt audio drivers can cause no sound issues across all media types, including MKV files.
- Press
Win + Xand select Device Manager. - Expand the Sound, video and game controllers section.
- Right-click your audio device and select Update driver.
- Choose Search automatically for updated driver software.
- Follow the prompts and restart your computer if an update installs.
Why this matters: Updated drivers ensure Windows can communicate properly with your audio hardware.
Alternative Method: Use a Different File Format
If none of the above solutions work, consider converting your MKV file to a more Windows-friendly format like MP4.
- Use HandBrake or any reliable video converter.
- Open the MKV file and select MP4 as output format.
- Start the conversion and then play the new file.
This can bypass codec or compatibility issues inherent in the MKV container.
Frequently Asked Questions (FAQs)
Why does my MKV file play video but no sound?
This usually happens because your media player does not support the audio codec used in the MKV file, or the audio track is disabled or corrupted.
Is VLC the best player for MKV files?
Yes, VLC supports a wide range of audio and video codecs and can play most MKV files without additional codecs.
Can Windows Media Player play MKV files with sound?
Windows Media Player often struggles with MKV files because it does not support all codecs by default. Installing a codec pack or using a different player is recommended.
Do I need to install codecs manually?

What if my audio drivers are up to date but still no sound?
Try uninstalling and reinstalling the audio drivers or check Windows audio settings to ensure the correct playback device is selected.
When Nothing Works
If you’ve tried all the above steps and still have no sound, it might be a problem with the MKV file itself. The audio track could be corrupted beyond repair.
In such cases, try downloading the file again or obtaining a different copy. You can also seek help on official forums like the Microsoft Support or media player community pages.
As a last resort, professional video repair tools may recover corrupted audio tracks, but these are often paid solutions.
