Qubes and PulseAudio bug

After updating dom0 I experienced different malfunctions related to how my HP zBook 14″ works with Qubes. The most annoying were:

1. no correct functioning of the Fn keys
2. audio missing at all
3. shutting down not working
4. random freezing of qubes-manager and other tools.

I was thinking I was in the middle of a transition between Qubes 3.0 and 3.2.

But I was wrong! There was a single bug related to the audio server used in Qubes (PulseAudio) that was unable to find and drive the audio card.

The solution is easy, the good things happend after you reboot:

as root, in dom0 create /etc/modprobe.d/my-alsa.conf with this line

options snd-hda-intel enable=0,1,0
