[2020] Anyone having mic issues on PC?

It says DEFAULT COMMUNICATION DEVICE

and when I change it, it doesn't stay changed.

I even go to battle.net app to change it, and its actually set correctly in there, but the game itself does not keep these settings, and thus I cannot talk with anyone in game chat. WTF is going on? Please help if anyone knows how to fix this or if its a common issue with anyone else on PC.

edit: seems that many of us have same issues. We should probably tweet at https://twitter.com/Treyarch and hope they see and can issue a patch.
