snd-hda no sound whatsoever

[Eitan Adler]

I have no sound whatsoever.  Speakers are plugged in and turned on.
I'm not sure what debugging information I need.

$kldstat |grep snd
 5    1 0xc5985000 19000    snd_hda.ko

$cat /bin/sh >/dev/dsp
  Produces no sound

$sysctl -a|grep hda
  http://isis.poly.edu/~eitan/files/hda-sound-problem-sysctl-output.txt

$cat /dev/sndstat
  (hw.snd.verbose: 4)
  http://isis.poly.edu/~eitan/files/hda-sound-problem-sndstat-output.txt

Any ideas?
