MKV (Matroska Video) is a powerful and flexible multimedia container format that stores video, audio, subtitles, and metadata in a single file. However, it’s not uncommon for users to face an issue where the video plays but there’s no sound — especially when using Windows Media Player.
Don’t panic! In this guide, you’ll learn step-by-step solutions to fix MKV files that have no sound. Whether it’s a minor volume setting or deeper file corruption, we’ll walk through each fix clearly — with no shortcuts, no confusion, and no fluff.
Let’s get started!
🔍 Why Does an MKV File Have No Sound?
Before jumping into fixes, it helps to understand the possible causes behind this frustrating issue:
- The volume is muted or too low in the player or Windows system.
- The wrong output device (speakers/headphones) is selected.
- Outdated or broken audio drivers.
- Windows Media Player doesn’t support the MKV audio codec.
- The MKV file itself may be corrupted.
Now that we know what could be going wrong, let’s move to the next section and solve it step by step.
🎧 Step-by-Step Fixes for MKV Files with No Sound
Let’s start with the basics and gradually move toward advanced solutions.
✅ Step 1: Check Volume in Windows Media Player
Sometimes the fix is simpler than you think.
- Open the MKV file in Windows Media Player.
- Look at the bottom control bar.
- Click on the speaker icon and make sure it’s not muted.
- Adjust the volume slider to increase the sound level.
🔊 Tip: Also press
Ctrl + ↑to increase the volume from your keyboard directly.
✅ Step 2: Check Your System Volume
Next, let’s ensure your Windows system volume is working correctly.
- On your taskbar (bottom-right corner), click the speaker icon.
- Make sure the volume is turned up and not muted.
- Try adjusting it and see if sound returns.
✅ Step 3: Check the Output Device in Windows Settings
Sometimes, Windows might be sending audio to the wrong device — like a disconnected Bluetooth headset.
- Right-click the speaker icon in the taskbar.
- Click “Open Sound Settings”.
- Under the “Output” section, make sure the correct device is selected:
- Headphones
- Speakers
- External monitors (with audio support)
🎧 If you use multiple devices, unplug them and plug them back in to force a reset.
✅ Step 4: Update Your Audio Drivers
If everything seems fine but there’s still no sound, your audio driver might be outdated or corrupted.
- Right-click the Start menu, select Device Manager.
- Expand the “Sound, video and game controllers” section.
- Right-click your audio device (e.g., Realtek Audio).
- Select “Update driver”.
- Choose “Search automatically for drivers” to let Windows find the latest version.
🔁 Restart your computer after the update completes.
✅ Step 5: Restart Windows Media Player
Sometimes a simple app refresh can help.
- Close Windows Media Player completely (not just minimize).
- Reopen it and try playing the MKV file again.
Still no sound? Don’t worry — let’s try a more reliable media player next.
✅ Step 6: Play the File in VLC Media Player
Windows Media Player doesn’t support all audio codecs used in MKV files. The solution? VLC Media Player.
- Download and install VLC Media Player (free).
- Open VLC, then drag and drop your MKV file into the window.
- VLC supports almost every audio and video format — and should play the file with sound.
🧡 VLC is highly recommended for MKV, FLAC, AAC, and other non-standard formats.
🛠️ Step 7: Repair Corrupted MKV File with 4DDiG
If none of the above worked, there’s a chance your MKV file is corrupted. The best way to fix this is to repair it using 4DDiG File Repair Tool.
Here’s how to do it:
- Download and install 4DDiG File Repair.
- Launch the program. Click on “Video Repair”.
- Click “Add Videos” and upload the MKV file that has no sound.
- Click “Repair All” to begin the process.
- Once complete, preview the repaired file.
- If everything looks good, click “Save All” to save the fixed file to your PC.
🛡️ 4DDiG supports MKV, MP4, MOV, AVI and more — and is built for audio/video recovery.
🔁 Step 8: Convert MKV to MP4 Using VLC
Another effective method is to convert the MKV file to a more compatible format like MP4. VLC makes this easy too.
Steps:
- Open VLC Media Player.
- Click “Media” > “Convert/Save”.
- Click “Add” and select your MKV file.
- Click “Convert/Save” again.
- Under Profile, select “Video – H.264 + MP3 (MP4)”.
- Choose the destination folder and filename.
- Click “Start” to begin the conversion.
💡 This will create a new MP4 file, which may solve the sound issue entirely if it was codec-related.
