I ran a yum update and went from kernel -122 to -127. Rebooted without the
camera, plugged it in, and mic seems to work now.

This is what I now see in dmesg

I have this nagging feeling I am getting audio input from bot the headset
and the camera now... Selecting one or the other (even selecting internal
audio card without any mic) I am getting the same readouts in the 'input
level' indicator when I make a sound. It doesn't matter which mic I enable
or which one I make the sound into...
