What should I do when Ubuntu freezes?
I recently installed 12.04 (32-bit) on a new PC build (ASUS Sabertooth-Z77 motherboard with Realtek ALC892 audio chipset). I have no sound, the volume control panel applet doesn't show a slider, and I can't access the Sound Settings.
- Attempting to access the Sound Settings from the System Settings window causes that window to become non-responsive.
- Firefox and Chrome both become non-responsive when something in them triggers an audio event, e.g. attempting to play a flash video or receiving a message in FB.
- Banshee and Rhythmbox both become non-responsive immediately upon loading.
- Pulseaudio does not respond to CLI commands, including --kill.
- Attempting to play a .wav file from CLI with aplay hangs until I Ctrl+C it.
If I uninstall Pulseaudio, ALSA takes over and I get audio, but I couldn't get a panel applet to display or a volume button response even after attempting the instructions here.
I tried purging pulseaudio, deleting ~/.pulse and reinstalling, to no effect.
aplay -l returns the following:

Not sure what else to try, any suggestions would be appreciated.
