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")
