Bug#464786: gtkpbbuttons sometimes prevents audio from working (makes /dev/dsp busy)

[Vincent Lefevre <vincent@vinc17.org>]

Package: gtkpbbuttons
Version: 0.6.9-1
Severity: normal

Each time I tried to play audio (ogg stream), I got an error. For
instance, with ogg123:

ALSA lib pcm_dmix.c:866:(snd_pcm_dmix_open) unable to open slave
ALSA snd_pcm_open error: Device or resource busy
Error: Cannot open device alsa.

I tried other devices, like oss, and still got an error. Ditto with
VLC using esd (/dev/dsp: Device or resource busy). I saw with lsof
that gtkpbbuttons was using /dev/dsp0. I killed the process... and
alsa and esd now work again.

Note: I restarted gtkpbbuttons and no longer have this problem. So, it
seems that under some conditions, gtkpbbuttons is locking /dev/dsp.
