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.
What worked for me (from an idea further down the page)
1. Quit Teams
2. Go to C:\users\<yourname>\AppData\Local\Microsoft
3. Just delete the whole Teams folder along with TeamsMeetingAddin and TeamsPresenceAddin. If you can't delete it then you may still have Teams running so try quitting it again rather than just closing it - look in the taskbar for the icon
4. Download Teams from https://www.microsoft.com/en/microsoft-365/microsoft-teams/download-app#desktopAppDownloadregion (or just Google Microsoft Teams download)
5. Reinstall
When I reinstalled everything was still there but now I could see my audio devices again. Just uninstalling didn't do it as AppData was still left there I guess
This worked very well. Thanks.
