Working.

Driver: snd-hda-intel (Alsa)

[edit] How to tell if this is your card 

# lspci |grep "HD Audio"
00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03)

For general information on how to detect your sound card, see Category:Sound cards

Not all Intel HD audio are the same. A lot of bugs depends on the codec or the model. To tell what codec you have : 

~> grep Codec /proc/asound/card0/codec*
/proc/asound/card0/codec#0:Codec: IDT 92HD71B7X
/proc/asound/card0/codec#2:Codec: Generic 10de ID 3

In this case we have an IDT 92HD71B7X and also a generic codec.

[edit] Notes

  1. You may need to correctly set the model parameter to the module to get all your sound card features. Try for example model=6stack-dig if you were expecting a digital out and couldn't find it on your mixer (it might show up as 'IEC958') - but there are a few different potential options for S/PDIF output.
  2. If you have a laptop and aren't getting sound on your headphones (or speakers aren't auto muting) try model=laptop
  3. You can get the full list of models to try from /Documentation/sound/alsa/ALSA-Configuration.txt in your kernel source tree. You can find this file online here http://www.mjmwired.net/kernel/Documentation/sound/alsa/ALSA-Configuration.txt
