No audio for video files in Desktop app
- May 20, 2020
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.
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

I can confirm I am having this same issue. No audio on video playback on Teams iPhone app. Videos work fine when I am on my Windows 10 desktop Teams app. The original file I made is fine (I am the one who uploaded it). When I use the “make it available offline” function to download on the iPhone, I still have no audio. Not only that but I couldn’t find where the file downloaded to. I have also experienced issues where audio in a file downloaded from Teams on my Windows 10 desktop is out of synch, and the frame rate of the file is changed from the original upload (upload from another person). I have uninstalled and reinstalled the app on both devices. I have restarted devices. I am using this app for school purposes to submit documents for review by the team.
