Unable to select microphone or speaker device in Microsoft Teams (Windows 10)
Microsoft Teams is currently unable to make/receive calls due to the app being unable to set a Microphone or speaker device. The 'Audio Devices' profile within settings is set to 'Custom Setup' and...
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.
Eliott I had the same problem. Teams would not make or receive calls and the settings had only "Custom" available, with no speaker or camera available for selection, despite them working fine with other applications, including Teams in a browser.
Removing the Teams cache file in AppData and updating drivers had no effect.
The problem turned out to be an issue with the Visual C++ redistributable library on my machine. Reinstalling the latest VC++ library and then reinstalling Teams fixed the problem.
