Found a crapy workaround here: http://lkml.org/lkml/2013/1/13/11
Get the hda-verb (e.g from here: https://launchpad.net/~diwic/+archive/ppa/+build/2768994/+files/snd-hda-tools_0.20110516%7Eoneiric1_amd64.deb )
Extract the 'hda-verb' from the deb package and then run as root:
hda-verb /dev/snd/hwC0D0 0x1f SET_POWER_STATE 0
Turns back the sound, lets see for how long..
