Public bug reported:
I commented out "load-module module-hal-detect" and added in "load-module
module-alsa-sink device=dmix" as well as "load-module module-alsa-source
device=dsnoop", in an effort to get PulseAudio to use dmix so that Skype can
coexist with it. However, occassionally, I get some assertion failed:
pulseaudio: pulsecore/source.c:273: pa_source_post: Assertion
`PA_SOURCE_OPENED(s->thread_info.state)' failed.
This is very similar to the case reported here:
https://tango.0pointer.de/pipermail/pulseaudio-discuss/2007-October/000800.html
Appropriate snippet:
Second, PulseAudio would crash on startup with this message:
I: module-suspend-on-idle.c: Source bluetooth.monitor idle for too long,
suspending ...
pulseaudio: pulsecore/source.c:273: pa_source_post: Assertion
`PA_SOURCE_OPENED(s->thread_info.state)' failed.
(In fact, nobody ever opened that source.) To cure the problem I omitted
loading module-suspend-on-idle, but it looks like a nice feature, and is
there something I might have done / not done to break it?
In my case, omitting module-suspend-on-idle also stops this from
happening.
Also this problem happens randomly. Sometimes it works, sometimes it
doesn't. As such I suspect it's some sort of race condition.
Backtrace when it does happen:
