Thanks, Don. Here is a recap of my situation, in case it might help.
Unable to hear audio FROM virtual PC. Audio TO virtual PC OK.
Local PC setup:
Teamviewer, options, audio configuration:
Voice Input, Vol Max, mute unchecked.
Signal bar moves with audio into PC (via mic)
Noise Threshold – Auto
Audio TO virtual PC OK (ie, K3 will transmit).
Voice Playback – clicking >, can hear ping
But no audio FROM virtual PC
Virtual PC
Same options setup as Local PC.
Voice Input, signal bar moves with audio into virtual PC (IE, K3 audio output is getting to Teamviewer)
Teamviewer, Communicate: Checked Computer sound. Call Via Internet. Start Internet Call
Audio FROM Local PC OK
Latest Teamviewer software, Ver 13.1.1548. Win10, latest updates on local and virtual PC’s. Kaspersky Total Security software.
Also tried with Local laptop running Win7. No difference.
