Public bug reported:
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 รณ 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.
Thx.
