Managing sound and video settings during Teams meetings and calls
I fixed the issue - If you are using Sony Headphone wh-1000xm5 to connect multiple devices simultaneously - you will lose it as microphone on windows 11.
Go to Sony app on your iphone/android and turn off "Connect 2 devices simultaneously" - then join in using Bluetooth to windows 11 and check "Audio" under Bluetooth & Devices -. Devices to see that WH-1000XM5 is "Connected, mic, audio" and you are all set.
You cant use it to connect to your phone and Laptop as you will keep losing Microphones access on windows 11
Sad but that is a discovery ! - not a solution
