Alexander,
    Ok, I got stuck again. Can you possibly push me in the right
direction (complete verbose dmesg attached)? The line-in and SPDIF
(not so much of a concern) are the only issues that I'm aware of. I'll
have to open up my case and wire up the front ports in order to test
them for you.
    Also, the knobs that show up in xfce4-mixer are completely useless
for snd_hda(4) (every time I move the sliders it sets the volume back
to 0). Is this a known issue?
Thanks,
-Garrett
