** Description changed: Ubuntu 12.04 LTS Precise Pangolin freezes most of the time when trying to use HDMI audio (in particular from google-talkplugin, mplayer, vdr- sxfe, vlc, xine) up to and including the current Kernel 3.2.0-49 without putting snd_hda_codec_hdmi on the /etc/modprobe.d/blacklist-oss.conf (thereby losing sound over the Nvidia outputs). Invoking pavucontrol with snd_hda_codec_hdmi loaded almost always results in a crash that makes even Ctrl-Alt-SysRq inaccessible. Freezes also occurred with both hw and plughw devices of the Nvidia HDMIs under ALSA when pulseaudio had been uninstalled for testing. According to https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1173769 #3 there is "a kernel issue which most likely is to happen with Nvidia graphics", this is also not fixed by using https://code.launchpad.net/~ubuntu- audio-dev/+archive/alsa-daily/+files/oem-audio-hda-daily- dkms_0.201307180553%7Eprecise1_all.deb according to https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1169984 #16.
