Teams changes the microphone volume levels to 0
I have a USB microphone that is working properly in other applications. When I use this as the microphone in Teams, it works for a second or two and then the volume is set to zero. At this point, it does not work in any application until I go to the windows sound settings and restore the volume which is set to 0.
I have the same problem. Microphone gain/sensitivity is set to 0% as soon as I open the device setting in MS Teams.
It seems this is known and Microsoft has not bothered to change at all. Really annoying. There is a similiar vote under "Microphone adjustment level"
