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...
