Default Yet another misbehaving Sound System - HP Pavilion dv4

Sorry for muddying up the other thread with my situation. I thought
we were trying to learn more about the hardware. This is Sidux on
AMD64 Turion dual core, stock Sidux kernel. I've heard no sound from
it except when I accidentally booted into Win*. alsaconf runs without
error, alsamixer says the levels are reasonable, I've tried fiddling
with "model=blah" in /etc/modprobe.d/sound, to no effect.

Advanced Linux Sound Architecture Driver Version 1.0.18rc3.
--------------------------------------------

This part has me suspicious that alsa's just picking up the wrong
device. Why are there two:

--------------------------------------------
0 snd_hda_intel
1 snd_hda_intel
0 [SB ]: HDA-Intel - HDA ATI SB
HDA ATI SB at 0xd2500000 irq 16
1 [HDMI ]: HDA-Intel - HDA ATI HDMI
HDA ATI HDMI at 0xd2410000 irq 19
--------------------------------------------

--------------------------------------------
(0) newmil [root] /root_ head -n 1 /proc/asound/card0/codec*

(0) newmil [root] /root_ head -n 1 /proc/asound/card1/codec*
Codec: ATI ATI RS690/780 HDMI
--------------------------------------------

I wonder if it's just a matter of blacklisting the first one?

More data:

--------------------------------------------

FWIW, I just successfully tested using headphones, so the sound
delivery programs work. Just not audio.
