Hda

From the ALSA wiki

Just type this two commands and it will play every sound you want:

modprobe snd_hda_intel

Other required module like snd-hda-codec will automatically be installed.

For a permanent setup, you should run alsaconf

Note that :

• Dolby digital may not work on some chips (like ALC883). This problem has been fixed and will be available with ALSA > 1.0.14rc3
• hda-intel driver duplicate stereo analog output on all other channels and on spdif output. You will be able to diable this feature with the mixer with Alsa > 1.0.14rc3

If only certain aspects of your hardware work, e.g. the headphones but not line out, then you can try passing one of the following model arguments:

Asus

modprobe snd_hda_intel model=asus

other possible models you can try are:

• 3stack (3-jack in back and a headphone out)
• 3stack-digout (3-jack in back, a HP out and a SPDIF out)
• 5stack (5-jack in back, 2-jack in front)
• 5stack-digout (5-jack in back, 2-jack in front, a SPDIF out)
• 6stack (6-jack in back, 2-jack in front)
• 6stack-digout (6-jack with a SPDIF out)
• w810 (3-jack)
• z71v (3-jack [HP shared SPDIF])
• asus (3-jack)
• uniwill (3-jack)
• F1734 (2-jack)
• ref (Depends on the model used)
• acer (Acer laptops)
• acer-aspire (Acer Aspire laptops)

Troubleshooting:

• To get help be sure to include the content of the codec#* file (e.g. /proc/asound/card1/codec#0)
• Sometime this chip has some weird problems on the ASUS P5N-E SLI mainboard (Realtek ALC883 6-channel CODEC), it seems that there's some IRQ conflict between the ohci_controller and the audio controller (in the manual tells that they shares the same IRQ), the sound results choppy and distorted far away to been listenable. Still searching for a solution.
• If in doubt, check the source code for alsa. There's a number of model codes not listed here which can be found under the sound/pci/hda/ folder; for example, patch_realtek.c contains the model codes for the ALC883.
