Microphone doesn't turn off after a team call
It will not let go of the BT microphone after a call making the phone think it's still in a call. If you try to play media you cannot hear anything and if you try to change the volume it shows that it's changing the call volume. I'd hate to think what would happen if someone needed to make a 911 call after using teams. The only way to get it to get your audio device back is to force stop Teams.

I have this issue on Kubuntu 20.10, fresh install of both OS and Teams.
