I downgraded to 2.6.31.5-127 and I still have the same issue. The odd
thing
is that the slider volume control on my keyboard still "works" in the sense
that the computer knows to adjust the volume--but it just goes to a dummy
output device. I notice that the hda-related modules aren't loaded, so I
tried loading those. No success there, however. It might be useful to note
that I was trying to get a USB TV tuner to work earlier--in so doing perhaps
something went wrong with the sound modules.

Hi,
after much searching, I've found a solution for my laptop HP dv3-2130el
sound problem in the Ubuntu forum. The modprobe.d/ structure is different,
so I've modified /etc/modprobe.d/dist-alsa.conf adding the following line:
*options snd-hda-intel model=hp-dv5 enable_msi=1
*
Please, note there are different value for the model= parameter and I've not
found a good source of documentation helping the choice.
Try google with the specific string model of your laptop and "sound+linux"
The problem here arise from the chip-set being a Family with different
implementation schema; similar products (eg Pavillion dv from HP) may use
different values.
