Additional meeting and call-related features and issues within Microsoft Teams for business
I've had an issue where I join calls, Teams would crash my audio and I would get messages in the Teams call that Teams could not detect my audio or mic. I would have to quit Teams and sometimes restart my computer in order to restore my audio after Teams crashed my drivers. I recently found that I could run 2 commands from an admin Powershell or command prompt WITHOUT having to quit my Teams call:
net stop audiosrv
then
net start audiosrv
After the service started back up, Teams automatically detected my mic/speakers and I could hear and talk in the call.
