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.

It sounds like you have a kernel issue. Do you remember when the sound
stopped working? If you do, and you have multiple kernels installed, I
would try booting the system with an earlier kernel
(Command line: rpm -qa --last kernel ).
See if that fixes the sound issue. Good luck,, and let us know (or
file a bug in bugzilla under "kernel")

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.
