I have modified /etc/modprobe.d/sound with :
snd-hda-intel index=0 enable_msi=0

I attach the log of alsa-info.

I compile the kernel myself. So perhaps I forget something...I have
uploaded on the kernel bugzilla
(http://bugzilla.kernel.org/show_bug.cgi?id=15399) the 2 config files of
my custom kernels : one for the 2.6.32.9 which works and one for the
2.6.33 which doesn't work.
