Pulseaudio uses 100% CPU at the time of the freeze, and all sound applications (rhythmbox, totem, firefox with flash, etc) become unresponsive.

Please report this issue to the ALSA developers. main.c: Called SUID root and real-time and/or high-priority scheduling was requested in the configuration.
