Well, finally someone who gives a good solution. Thank you very much!
Thanks. Been trying to solve this problem for a long time. My problem was that I have the same chip, but the motherboard, P5G41-M LX comes with a 3-stack-dig. But I could'nt get the subwoofer to work. In order to get surround at all I had to add options snd_hda_intel model=3stack-dig in the /etc/modprobe.d/alsa-base.conf. But as I said, it wouldn't output sound through the LFE. Changing the to model=6stack-dig worked just fine.
Nope, didn't really work. Audio came from external speaker, but couldn't disable internal one.
