I use airshokz, earphones. I used to hear the beeping. To get rid of the beeping, I joined a TEAMS meeting, then muted myself on the Teams app, triggering the beeping, then I pressed the power and volume buttons on the earphones, simultaneously, for 3 seconds, until the airshocks voice command stated "Mute Off". The beeping went away, and i stayed muted on TEAMs.
Hopefully this helps.
Turning mute on/off with the headphones is a normal function. You don't need to hold all three buttons - you just need to hold both volume buttons for three seconds to turn mute on or off.
I tried your suggestion and it worked for a moment. The headphones (Audrey) said "mute off" and I stayed muted in Teams. However, when I unmuted myself in Teams and then muted myself again, the beeping resumed, so this is not a permanent solution.
Also, trying this while holding all three buttons produced the same result.
So far, the only solution seems to be using the web version of Teams, rather than the desktop version. This issue does not occur with the web version.
