How to enable ALSA Analog 5.1 Sound on Nvidia ION

I recently had the problem to enable 5.1 Sound with 3 click outputs on an Nvidia ION board. By default Linux configures it with only one plug configured as output. After some research I found a solution in the OpenSUSE Wiki you have to set during module loading to get it working. Basically you have to add

options snd-hda-intel model=3stack-6ch enable=1 index=0

to your modeprobe.conf to tell the driver to use all its 3 plugs as output. After you loaded the modules like this, alsamixer will show you all the 6 channels, so you can unmute them.

HDMI

To be able to use audio over HDMI, the following requirements have to be met:

  • alsa 1.0.19
  • snd-hda-codec-nvhdmi has to be loaded before snd-hda-intel
  • Unmute IEC958 mixer

Maybe the following has to be added to /etc/asound.conf

pcm.!default hdmi:NVidia
