I found this on another site and I finally have this working:
sudo adduser myuserid audio
sudo adduser myuserid video
Logoff and back on and I now have audio, video and microphone

I installed MS Teams for Linux on Ubuntu 20.04 a few weeks ago. It worked perfectly well, until earlier this week, the microphone stopped working. I have a mic in my headset, and a mic in the Logitech camera, both work ok for all applications, except with Teams. When I use the mic, I see the record sound meter in Ubuntu sound record it, but the Teams sound meter in "settings" doesn't.
What can I do?
edit:
This morning, audio worked on MS Teams. But when the meeting actually started, a popup appeared saying "your microphone does not work" and it stopped working. It must be a bug in MS Teams, otherwise it couldn't have worked for the first 5 minutes.
