Hi @IBN ,
We have had 3 users complain that they are unable to have consistent microphone usage after updating to Windows 11.
In order to help narrow down the issue, may I know if there are other users in your environment who have also updated to Windows 11 but haven't met this issue? If yes, have you noticed any obvious difference between them and the problematic 3 users?
And would you mind providing more details about how you managed to rule out the factor of "a driver/firmware/hardware issue"?
Actually I am also using Teams desktop client on Windows 11 myself, but so far haven't experienced any audio issue during daily use. And after a lot of research, I can barely find other reports about similar issue.
Given the current situation, I'd suggest testing in Teams web client via teams.microsoft.com and see if there would be any improvement.
Besides, I can understand that you may probably eliminate the impact of hardware for some reason, based on my personal experience, it's also worth trying to test on one of the affected device by disabling the GPU hardware acceleration and check how it goes.
