I take this statement back. I've recompiled alsa-driver-1.0.9RC1 and can
now restart alsa using using the old CCRMA script in /etc/init.d and it
DOES get the hdsp firmware loaded, despite the error. Very nice.

Running hdspmixer resets levels OK.

OK. I think my hesitancy is about whether I have an appropriate
.asoundrc. So, let me ask more generically. A command like:

aplay -D dmix:SLAVE=\"hw:0,0\",RATE=44100  [file.wav]

should work, yes?

Thank you. I can certainly work with amixer. I appreciate the
consideration, too.
