Hello, I'm also affected by this shutdown issue and I also hear no sound. I tried the changes suggested by Daniel. Nothing changed.
In : System > Preferences > Sound, when I hit thetTest button while "ALI 5451 ALI 5451 (Alsa)" is selected I have this error : audiotestsrc wave=sine freq=512 ! audioconvert ! audioresample ! gconfaudiosink profile=music: Could not open audio device for playback. I hear no sound when choosing any other option including PulseAudio. It may be related to something else than to alsa-utils.
