Unable to select microphone or speaker device in Microsoft Teams (Windows 10)
I posted about this on the regular Microsoft community forums and someone pointed out that their issue was that Teams seemingly has an incompatibility Elgato's 4K60 Pro Mk2 Capture Card, and this was definitely the issue for me.
No solution still, other than simply removing the cards from my system (not really an option)... so the workaround is just using the browser version of Teams which is inferior, especially for screen sharing and video calls. Hopefully they can fix it sometime, but seeing the volume of people coming forward with this bug I'm sure there is a variety of other hardware that is incompatible.
Nevertheless, quite odd especially considering that said hardware works with the browser version of Teams which must share almost entirely the same code base.
What worked for me on Windows 10 was to go to the Sound Mixer Options (which seems to also be called (App Volume device preferences). This lists apps with the volume, Output and Input Devices. Toggling the Output device from default to the specific option for my headset got this working again in the Teams app.
