Double checked all things that could make problems, alsa version, kernel
configuration, lib version, i dont find any solution.
Audio is cracky, some times does not work, front and rear mic does not
work, I applied the patch you suggested Raymond, nothing changed.
Do I open a separate thread?
If could help some times, when I start virutalbox with windows 7 or
windows xp machine image, audio starts work well, no noise no problems,
but after a little usage (an mp3 with mplayer) noise is back and mic
stop working again, i search in dmesg for any info about, but the
messages are always the same.

this is my last alsa-info
http://www.alsa-project.org/db/?f=9806a84f0d24e576b8b84524a7fb46a3f3703800
my latest kernel config (sound-2.6 Takashi's git)
http://valeriotesei.com/alsa/kconfig

There is a debug tool to show connections/pinstatus on windows7 to try
replicate those connection/pinstatus on alsa?
