pcm_pulse.c:361: pulse_write: Assertion `pcm->stream' failed.

Ubuntu: 9.04 x86
Pulseaudio: 0.9.14
ALSA: 1.0.18

$ cat .asoundrc
pcm.bluetooth {
 type bluetooth
 device 00:02:78:DE:09:43
 profile a2dp
}

I use bluetooth headphones. And after little playback, applications crashed with assert: pcm_pulse.c:361: pulse_write: Assertion `pcm->stream' failed.

this bug is easy to trigger.

pulseaudio -k while an alsa application is running. I'd say 9/10 you get it.

I have a patch to resume automatically when such thing happen.

It has been tested with gstreamer alsasink and mplayer. It is not exactly perfect. If you kill pulseaudio quickly you can trigger some loops in mplayer.

Also, there are some FIXME in the patch.

no more assert(pcm->stream)!!!

Hmm, the assert()s have now been fixed in ALSA.

I am not sure if I really like the idea of reconnecting here. PA dying and device suspend are very different cases. And I am not sure we want to create the impression that PA going away is equal to a system suspend.

I think PA dying is more like hot-unplug of hw, then suspending of hw. And so I think in that respect the current behaviour makes more sense.
