[pulseaudio-discuss] pulseaudio and NoMachine: microphone not working

I'm remoted into a Linux VM via NoMachine. NoMachine presents the client
machine's microphone as a pulseaudio source. I can run Audacity on the
VM and record sound captured via the client's microphone. However, other
applications like Firefox, Chrome, Slack, WebEx, etc. don't seem to see
the NoMachine microphone pulseaudio source. Making the NoMachine source
be the default source does not fix it. test.webrtc.org says "[FAILED]
Failed to get access to local media due to error: NotFoundError".
NoMachine also presents the client's speakers as a pulseaudio sink. I
can play a sound on the VM and it plays via the client's speakers
without a problem.
The VM also has a (virtual) sound card. Applications appear to want to
connect to and use the microphone source of the sound card, instead of
the NoMachine microphone source. Is there a way to "merge" the NoMachine
source into the sound card's microphone source?
With the sound card's mic source as the default, test.webrtc.org sees it
but complains that there is nothing on the channel and suggests that
perhaps its muted.
