Part of the problem was that I was using an older kernel where the
snd-usb-audio module didn't actually do anything with the mic. 2.6.26.5
vanilla works better. But still, Gentoo's a little less automatic with this
sort of thing. By setting up a ~/.asoundrc file containing
pcm.card1 {
type hw
card 1
}
...I could then do "arecord -D card1 -f cd -c 1 test.wav" and actually record
sound from the mic. Leaving -c off didn't work; you have to specify
something. The main problem now is that there's no "+20dB mic boost"
available, so everything that's recorded is *really* quiet. Well, sox can
fix that....
