Title:
[armel] Pulseaudio crashes other program using sound: Assertion
'pthread_mutex_unlock(&m->mutex) == 0'
Status in pulseaudio package in Ubuntu:
Expired
Bug description:
Whenever a program tries to use sound in anyway (and in some wierd
other cases like using tab-completion in a terminal) the program just
crashes with
Assertion 'pthread_mutex_unlock(&m->mutex) == 0' failed at
pulsecore/mutex-posix.c:106, function pa_mutex_unlock(). Aborting.
Aborted
Because it lets metacity crash whenever I use tab in a terminal, it
renders my system useless.
I found solutions for meego her:
https://bugs.meego.com/show_bug.cgi?id=13567
Easiest workaround was to disable PTHREAD priority inheritance feature that
was
the root cause at least on Your case.
For example to configure.ac, Add
pulseaudio_cv_PTHREAD_PRIO_INHERIT=no
Before
AS_IF([test "$pulseaudio_cv_PTHREAD_PRIO_INHERIT" = "yes"], [
AC_DEFINE([HAVE_PTHREAD_PRIO_INHERIT], 1, [Have PTHREAD_PRIO_INHERIT.])
])
I will to apply this fix and as soon as I get it working/compiled I'll
report back.
It might very well be a problem for armel with more than one core (as
suggested on the other site).
Expect:
Sound output (or at least a normal running program)
What happens instead:
Program crashes with
Assertion 'pthread_mutex_unlock(&m->mutex) == 0' failed at
pulsecore/mutex-posix.c:106, function pa_mutex_unlock(). Aborting.
Aborted
Steps to reproduce:
Open Settings/Sound/Output/Test and test one speaker
