Hi all,
it seems that i had similar issues since today and sorted it today. Since today When i am in a teams call i had only 2 options for audio:
* device
* speaker
Usually there was also "* bluetooth" and I assume this was coming with the last Android installation i did on the weekend... potentially Android changed something with auths for apps.
I was following some instruction from the beginning of this thread and cleard the cache for MS Teams on Android. after restarting MS Teams, Teams requested that MS Teams is allowed to search for nearby devices (i assume that was the one missing -> bluetooth is for nearby devices) and i approved it (i can hardly remembered, that I rejected it the first time). Another authorization request came up to make phone calls, I also allowed in MS Teams. First i was some kind of resistance to grant all those authorization, as i usually question, why this is needed. But based on my experience, when you have any kind of problem, just grant at the beginning all requested authorizations to see if it is working. Afterwards you can limit them again in android settings.
After that MS Teams showed me in a Teams call the option to choose
* device
* speaker
* bluetooth
and i was able to join calls again via bluetooth headset. Problem solved... lets see how long.
Hope that helps anybody having the same problem. I did not read this full thread with 6 pages, but i am really wondering why the MS-Support is not offering this walkthrough and pin it to the top of this thread as a potential solution... but maybe i just missed it. But when users having problems they want to have it sorted fast and not searching 100 of pages for a solution.
