In meeting problems with Sound

[slack]

I test my microphone and speakers prior to every call.  These calls are with people that I have used Zoom or Teams with.  I get into a period where they can't hear me, yet the testing works on my side.  They test theirs and it works, but we end up using cell phones.  

Technical Support from Zoom must have been eliminated as I get nothing.  Any thoughts on what to do.  I hate Teams, but might have to go there.
