Comment 2 for bug 318942

I managed to compile and install alsa-driver-1.0.19 from sources and sound is working for me now. (I did not update alsa-lib or alsa-utils, so I was not sure if this even has a chance of working out..)

The current output of the ALSA Information Script:
http://www.alsa-project.org/db/?f=33d727162af1551fc6ecb5aba93382ba67c9b3dd

(modules snd_hda_codec and snd_hda_codec_idt seem to have been added, and the resulting codec file in /proc has some differences)

I hope this ends up in a package anytime soon..
