[Pkg-pulseaudio-devel] Bug#522177: subscribe

[Giacomo Mulas]

I see the same problem, and I am willing to help.

Apparently, as far as I can tell, the problem is with the esound module:
when ANY esound client is connected to pulseaudio, pulseaudio keeps the alsa
device open and locked, so that nothing else can access it. Just even a
sound monitor (e.g. the one in gkrellm) is enough for this.
For example, I get:

gmulas at capitanata:~$ aplay /usr/share/sounds/phone.wav 
ALSA lib pcm_dmix.c:1008:(snd_pcm_dmix_open) unable to open slave
aplay: main:590: audio open error: Device or resource busy

The apparent effect, when using a gnome desktop with esound enabled, is that
ONLY applications going through pulseaudio (either directly or via esound
emulation) can use audio (as originally reported). So the problem is that
the pulseaudio server is locking the audio device. I have no clue as to why
this did not happen with the previous pulseaudio version (in sid) and does
with the latest released one. Please let me know if I can help to solve
this, as it is annoying (if I need e.g. to use skype I have to kill
pulseaudio...).

Bye
Giacomo
