Windows 10: replay of MKV files no loger working after upgrade

Hi,


I did the windows10 2004 update and after that my mkv files won't play anymore in Media Player, Photos, Movies & TV.

Apperently I am not the only one reading questions on the forum.

How can I fix that?

What is done during the upgrade ?

Was this detected during your QA of the upgrade?

What is the reason for still deploying the upgrade as is, if MS knows that this will impact a lot of users?

Thanks.

:)

 

Problem with mkv Files

Hi,

Experiencing issues in playing mkv files after an update may have something to do with the video card driver. If you have another mkv player app or program, we suggest that you try playing those files using another app or program to help us sort out this
issue.

If in case the issue persists, we suggest running video troubleshooter. Just click
Find and fix problems playing movies, television, or video on this
link.

You may also try rolling back the video card driver. Follow these steps:

• Right-click the Windows key and select Device Manager.
• Locate and right-click your display adapter, then select Properties.
• Select the Driver tab and click the Roll Back Driver option.

Let us know how it goes so we can further assist you.

Regards.

Audio disappeared - got it back but now have odd mkv problem

Hi. While working at my Windows 10 PC yesterday, I realised there was no sound. My media players gave video only and Avidemux gave a warning “Trouble Initializing Audio Device”. All the obvious checks suggested that there was no problem, drivers were up to date etc.

I went to the sound icon in the system tray and clicked 'Troubleshoot sound problems' which told me it had fixed something but didn't say what. I now have my sound back but with some new issues:

• my WMP no longer plays mkv files
• my mkv files no longer show a 'thumbnail', just the logo of whichever media player is set to play them.

Can anyone suggest what on Earth happened yesterday? Many thanks.

UPDATE: I've found one or two mkv files that DO work with WMP and show thumbnails(!!). But the vast majority of my mkv's have the highlighted problem. All very odd...
