@Wouter, some material to read: http://voices.canonical.com/david.henningsson/2011/12/08/audio-debugging-techniques/ - intro to audio debugging http://www.intel.com/content/www/us/en/standards/high-definition-audio-specification.html - the HDA specification The relevant code is located in the kernel, file: sound/pci/hda/patch_realtek.c http://www.kernel.org/doc/Documentation/sound/alsa/HD-Audio.txt - how to configure the HDA driver (although I doubt that will help in this particular case)
Good luck! :-)
