Hi all,
I'm using module-jack-sink and module-jack-source such that Pulse is
running above my Jack server. It doesn't give problems about half the
time, but sometimes the sound from my mpd server just dies. This is
because the pulse daemon has crashed and died (as shown by different PID
of pulseaudio before and after this happens). I've tried to run
pulseaudio in a terminal instead of daemonized, and in that situation I
can almost guaruntee a crash almost as soon as I start playing, though
if I start pulse with pulseaudio --start it seems to be able to work for
a much longer period of time.
In case it matters, my default.pa does NOT load module-hal-detect,
module-alsa-sink/source, or module-jack-sink/source, but the other
default modules are loaded. I have two scripts, pulse-nojack and
pulse-withjack, which would check for a running Jack server and
start/kill depending on the needs of the situation, as well as
load/unload the modules as needed.
I'm quite at a lost on how to analyze the situation, since there seems
to be a difference between running pulseaudio --start (which if I'm not
wrong is the same as pulseaudio, except it checks for a running daemon,
which I can confirm does NOT exist before running the command) and just
running pulseaudio.
What ist the pulseaudio -vvvvv output when this happens? If this is a
segfault, could you get me a stack trace please?

Hi Lennart, yes it is a segfault. I can reproduce it regularly here on
my laptop, will try in my office desktop when I get to work in a couple
of hours time. Basically I start up pulseaudio (just with pulseaudio
-vvvvv > pulselog.txt 2>&1), then my script uses pactl list to get a
list of modules (checking whether alsa is loaded, in this case it isn't
since its commented out from my default.pa), then starts up the Jack
server with jackd and calls pactl load-module on both
module-jack-sink/source. After that, I run paplay
/usr/share/sounds/alsa/Rear_Center.wav, and pulse dies AFTER playing the
sound. I include with this email my gdb stack trace, at the end of which
I'm left in gdb and quit using q, not sure what the *etc, etc* in the
wiki means.
