Managing sound and video settings during Teams meetings and calls
This seems to be the exact issue in my case.
If the bluetooth device has the option 'Phone calls' disabled in the device details menu, teams does not recognise it.
My problem with this, is that having bluetooth headphones with built in microphone, the 'Phone calls' audio quality is much worse than the media audio ( where there is no microphone available ).
I would like to find an option, to use the phone's built in microphone as an input, and the bluetooth headphones as output (in media audio mode).
Currently, I'm looking for a 'sound device manager' - like app, that can force input and output devices on a system level. Not sure if such an app exists, but it might solve the issue.
Let me know if you find anything useful!
