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 (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
Thanks Richard. Your solution worked for me.
Important point: This happened after the device was working fine for months. With no apparent action that triggered the error. I even went back to a restoration point and the error persisted.
However for me this is software related because full profile deletion and reinstall solves it.
JorgeRamirez - Full uninstall and reinstall did not fix the issue. Even a full new install on windows did not fix the issue. It has been determined that in this case the issue is hardware related, specifically an incompatibility between Team and the Elgato 4k60 Capture card.
When removed, the software functions without issue. When installed, the software will not detect input devices or allow the user to select any input. The Teams client is also prone to crashes.Eliott its all Elgato cards not just the 4K
