Then you need to killall pulseaudio for apps that use pcm starts working again.
(Question: How you can stop/start/restart pulseudio? In Ubuntu /etc/init.d/pulseaudio script is disabled)

And a extrange thing, perhaps another bug related: When you killall pulseaudio, gnome-power-manager get 100% CPU, and when you try to start pulseaudio again (/usr/bin/pulseaudio --log-target=syslog), then the WHOLE SYSTEM FREEZES and you need to restart.

If you need more information, please let me know.

Thx.
