Microsoft Teams : no audio device when Chrome is started before teams.

Teams definitely needs a way to make it STOP trying to select the input and output devices it is using and just always use the system defaults, because the way it manages audio device selection is completely broken. It doesn't notice Bluetooth devices that are connected after the app is started, and if you do manage to select a Bluetooth headset, it ends up using it for both input and output, even if you don't want this and explicitly selected another input device. It's ridiculous, no other app behaves in this way. 

I'm basically forced to use Teams through Chrome instead to avoid this problem.
