Remote cannot hear me on Ver. 13 1548

I am reposting in case something has changed since similar previous posts for ver 10 and 12.  We are using ver 13 build 1548.  I can hear the remote, but they cannot hear me.  My TeamViewer audio control panel shows mike is working, and sound levels are good when I speak.  I can see the audio settings on the remote, and it is set up properly for them as well.  Skype and other VoIP works with the same setup I have for TeamViewer

The issue is intermittent, and appears to be resolved if I do a complete reboot on my side, which seems odd? Whether or not the remote can hear me, my TeamViewer and Windows audio settings have not changed.

Update:  I have tested other selections for audio: Default Device, laptop embedded mike, and so on.  No change.  I can always hear remote, they cannot hear me, even though TViewer controls show my mike is working.
