Managing sound and video settings during Teams meetings and calls for optimal communication
I have found a workaround, for me anyway. Go into the device setting in Teams, leave the "Speaker" set to your headphones. Set the microphone to the PC's microphone.
Enjoy the sound of beep silence.
I would still like this to be "fixed", as the microphone in my headset works better than the PC one, but at least now my sanity may be saved.
