Ben,
Are you suggesting rebooting the host?
If that audio detection meter isn't moving, literally nothing else
matters. I don't recall anyone else suggesting that as a troubleshooting
step even though it should always be your goto for these kinds of
issues.
"that"? Rebooting? Rich

Step 1 for microphone troubleshooting is to verify that something is
being picked up. The Volume meter in pavucontrol will indicate that it
hears something, whether that be your voice, ceiling fan or ambient
static from a poorly configured jack.
Step 2 is to to verify that the audio picked up by the mic is correct.
Sometimes you see activity in the meter that is not what it should be.
e.g. background static from an unconnected audio device.
While running through steps 1 and 2, rebooting is a valuable tool to
verify that everything is loaded to a known good state. There are race
conditions involved with using pulseaudio. It has to load after the alsa
drivers, and if it crashes it has a tendency to auto restart as a
different process. By rebooting the host, you can be sure that
everything is loaded and linked together in the correct order, with the
correct permissions.
Are we still on for this afternoon? I want to pull this conversation off
of email entirely. Everyone is throwing ideas at you with no
coordination or focus. Some would even say that the definition of
insanity is doing the same thing and expecting different results. I'm
seeing over 25 emails from at least 7 different people and very little
meaningful progress. Maybe it's time to consider a different angle of
attack for this problem?
My offer of a quick web meeting for 5:30pm (or maybe even a phone call)
this afternoon still stands. I'm not going to offer further
troubleshooting advice for this issue via the PLUG list because someone
is just going to step all over it.
