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,
It has been several years (literally) since I have had major sound
problems
under Linux, since sound support has gotten much better. However, my
sound
recently stopped working, and I'm mystified. I'm using an HP Pavilion dv9700, which I believe uses an Intel HD audio card. I've gone through
a few
kernel upgrades on this machine recently, but support for these cards is enabled, so I can't imagine that's the issue. My sound card isn't listed
on
inspection of /proc/asound/cards and /dev/dsp is missing, though with
the
deprecation of OSS maybe this isn't even an issue. I'm pretty familiar
with
Linux, but not so much with sound cards, so I'm not really sure where to begin in resolving this. Any help would be greatly appreciated.
Hi Emerson,
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.
