Pulse sits on top of ALSA. If ALSA not happy, pulse not happy. Open 
alsamixer in a terminal, unmute your mike and set the volume level to 
about 80%. If your mike is your USB headset, then in alsamixer hit F6 
and chose that device to edit it's mike function. Use the m key to 
toggle mute on/off. ONCE alsa is happy, then go into pavucontrol and 
check it's settings. Everything should work at this point. Leave 
pavucontrol open, start your recording session test, and you should see 
the strength indicator bar move (under the recording tab) while you 
speak into your mike. You get to that point, you are arrived.

I have found that hot-plugging my USB headset is a problem. If I boot 
with it plugged in, no problems. Maybe a Bios vs OS thing, I have no 
clue. :) Ric
