Creative Labs Audigy SE. CL says they don't do Linux (screw them, too).

Tried that - no "Analog" devices visible.

I decided to use alsactl store and see what it showed. Aside from a
lot of stuff I didn't really understand, one thing stood out - the
Line Out Jack was turned off. I changed that and its volume, then one
other control (I forget which one) and ran alsactl nrestore, and voila
- sound.
Once I get rid of PA, how can I set my keyboard volume control to work
with ALSA?
Many many thanks!
