This seems to be at least part of the problem.  After setting the input
using alsamixer, I was able to record sound with both arecord and rec.

Also alsamixer always shows "line" as the active channel, as indicated
by "CAPTURE" in red above the level indicator, possibly in addition to
whatever other channel I select.

And I still can't get audacity (a rather nice sound editor I'm using) to
record anything.  But this is very likely audacity's problem.

BTW: Is there any documentation about what is the meaning of each of the
very large number of channels that alsamixer displays?  In particular
what are "EMU10K1 PCM", "EMU10K1 PCM 0".."EMU10K1 PCM 31", and the
various "EMU10K1 PCM Send" and "EMU10K1 PCM Send Routing" channels?  And
what does "pcm" stand for?  (I have found audio cards to be the worst
documented and most confusing of any hardware I have worked with.)
