hmm, that's interesting. I can't spot anything really wrong in the 
kernel logs -- all seems fine and the alsa-info dumps are basicly 
identical.

Can you try with latest upstream kernel? There have been a few patches 
related to ALC285 codec driver, like this one:

"ALSA: hda/realtek: fix right sounds and mute/micmute LEDs for HP 
machines"
