Managing sound and video settings during Teams meetings and calls for optimal communication
The workaround linked above didn't work for me, either. I had one that did work: when muted in Teams and getting the annoying beep, press and hold the volume up and volume down buttons at the same time. AfterShokz would say "Mute off" but Teams would still be muted, and the beeping would stop. But, today, that workaround no longer works. I would assume it's an update on the Teams end, but it shows last updated on 11/15, and nothing has changed on my AfterShokz, either. So I have no idea what made the workaround stop working.
I even tried resetting my AfterShokz with no luck.
