yes I could think of it. it changes for me if I set the input mic to the "Front Mic" (it depends on your card). You mentioned the mic on your usb is working, then it is a setting in your mixer that tells alsa to grabfrom the usb mic.amixer ... ... ...

(Line is self explaining) Check out your mixer settings (amixer, alsamixer or kmix/gnome-mixer) andswitch to the other mic - try the first command and the indicator #+ | 00%should change when recording some sounds. i.e. ###### + | 87%
It was muted. Ha! Discovered that in alsamixer eventually. Couldn't make sense of amixer output - is it reading the same config as alsamixer? It's got to be, right?
Alsamixer has a column for line, cd and mic which allowed me to take mute off from mic and now it comes thro from this mic on the soundcard to the speakers, but I still can't get anything with aplay or with audacity.
Audacity has recording device choices of ALSA HDA Intel ALC882 Analog hw:0,0, hw:0,1 and hw:0,2
Don't know what to make of it.
