Thanks so much for all your help with this.

I just used amixer to change volume and unmute Master, PCM, and Front,
and no sound.
Another potential problem that may or may not be relevant is that ALSA
sees two cards-- the Intel card and the NVdia Video card. I'm not sure
how to ensure that the signal is going to card0, the Intel card.
FWIW, the Intel card is on an Intel S5520SC workstation motherboard. In
an Ubuntu HOWTO (https://help.ubuntu.com/community/HdaIntelSoundHowto) I
found suggestions to run
cat /proc/asound/card0/codec#* | grep Codec
And I get
Realtek ALC 889
It suggests that you look up in a table what your model is, and I get
It then suggests that you change alsa-base.conf, which isn't feasible in
the install situation.
Any suggestions for getting this thing running would be really appreciated.
