--- Comment #25 from Santiago Garcia Mantinan manty@manty.net 2012-07-16 06:54:36 --- I have just tested 3.4.4 and I got no sound again, however this time the kernel said this:

[ 81.186129] hda-intel: IRQ timing workaround is activated for card #0. Suggest a bigger bdl_pos_adj.

I hope this helps!
