Confirming this bug, I see it too. I removed the info about the gnome- power-manager, that should be logged as another bug, this is just for blocking sound after resume.
** Description changed: Binary package hint: pulseaudio > aplay squish.au Sonando Audio Sparc 'squish.au' : Mu-Law, Ratio 8000 Hz, Mono [Suspend to Ram/Resume] > aplay squish.au ALSA lib pcm_dmix.c:874:(snd_pcm_dmix_open) unable to open slave aplay: main:546: error al abrir audio: Dispositivo ó recurso ocupado 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.
