Launching pavucontrol may still freeze the system, hence snd_hda_codec_hdmi has to be blacklisted (losing its required functionality), also under kernel 3.8.0-30 and even after a BIOS update to 1.32 (irrevocable, cf. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1203446/+attachment/3809189/+files/HPQFlash.png).
