No audio for video files in Desktop app
For video files which have been uploaded into a team or chat, when played back in the Desktop app there is no audio. Note, audio (mic and speaker) work perfectly in a meeting. It's just the playback...

Found it!!
For some reason, I had an app output override in place that was directed to my external audio interface.

Playing with this a bit more, I can see that Teams treats meetings as different audio output to that of playing a file. Hence why I could still hear audio in meetings, but not from files.
Chris, I appreciate your assistance on this anyway.

No worries,
If it is working on the other machine in this way then it looks machine specific. What is the machine? I guess it may be worth looking at the audio drivers etc. Does audio play through something like Windows Media Player or another app on the machine itself? Maybe try running through some of these?

Let me know, I am interested in trying to fix this one - as said, seen it a few times before
Best, Chris

Thanks Chris.
The machine is a Surface Book 2. I had done a system Reset about a month ago. But before then, Teams was working fine.
Absolutely everything else on this machine that has audio is working fine.
