MKV Files Don't Work Properly in Windows Media Player? How to Fix?

Windows Media Player is inbuilt media player software in Windows. The latest version WMP12 was released in October 2019 along with Windows 7 and now is also available for later Windows 8/8.1/10. It is some Windows user's first choice to play video files on PC. However, it usually fails to work with MKV video files. Sometimes, it gives a black screen with only audio. Sometimes, no sound can be heard.

Incompatibility is the reason why Windows Media Player won't play MKV files. Unfold the list of file types supported by Windows Media Player and MKV is not included. So, how can we fix MKV not playing issue in Windows 10/8/XP?

Solution 1. Convert MKV to WMP Acceptable Formats

WinX HD Video Converter Deluxe, which wraps the ability to change video format from MKV to MP4, AVI, WMV etc, is a good helper to fix MKV not playing issue in WMP. It has a straightforward design leading you to convert MKV to WMP in a few of clicks. With the utilization of GPU acceleration, it can deliver fast conversion performance. Also, the quality will not be scarified after conversion or compression.

Step 1. Launch this WinX MKV converter and click +Video button to load the MKV file which won't work with Windows Media Player.

Step 2. Output Profile pops up. Select a format available for WMP as output format, for example MP4 Video (codec: h264+aac). Click OK.

Step 3. Click Browse button to set a new destination folder. At last, click RUN button to start conversion.

Solution 2. Install MKV Codec for Windows Media Player

If you wouldn't like to convert MKV, the other way to fix MKV not playing issue is to install MKV codec for Windows Media Player.

There are several codec packs for computer or device – for example Media Player Codec Pack, K-Lite codec Pack - helping encode/decode MKV to achieve a smooth playback. You can download MKV codec pack in software download sites (CNET, Softnoic etc.) and install them on your Windows PC.

What we also want to notice you is that some MKV videos are encoded with HEVC which drives you to fail play MKV in Windows Media Player even though you have installed MKV codec. If you want to play all MKV videos, it is suggested to install codec pack supporting MKV and HEVC. Or, converting MKV to WMP is a much better choice.

"Freeware favorite HandBrake can handle some video formats, but it's a bit out-of-date, and nowhere near as comprehensive as a utility like WinX HD Video Converter Deluxe."
