I did that, and plugged it back into line out. That also explains why
things sounded so overdriven. But that also begs the question of why
mencoder selects the mic-in rather than the line-in. I did a test where
I ran an mencoder capture and watched the aumix display. When the
mencoder session kicked off, changed it to record from the line-in
interface. On playback, the audio and video was very, very slow.
Obviously, I'm missing something fundamental, and I feel that I'm back
to square one. How or why is mencoder forcing the record device to
mic-in, and why am I get the strange record behavior when I switch it to
the correct device?
