[M31EI Series, Realtek ALC861, Green Headphone Out, Rear] No sound at all

Hello there... i'm using PP 12.04, and I've tried the commom solutions... reinstall everything (alsa, pulseaudio etc...), purge and reinstall, test with aplay, and etc... nothing seem to bring my sound back... This is not muted, or anything, no profile works with audio, and it was working fine, before last upgrade (02/13/2012 - 15:00).

Can anyone help me, please?

I'm here to clarify any questions... thak you all. :D
