This is probably a known issue, but I'm constantly hitting
a deadlock when running Pulseaudio (0.9.7) with SCHED_FIFO
(--high-priority=1).
I can reproduce it as follows:
- run pulseaudio (self-compiled, debian stable) with --high-priority=1
- first client: while [ 1 ] ; do aplay -D pulse foo.wav ; done
- second: while [ 1 ] ; do aplay -D pulse foo.wav ; done
At some point, pulseaudio gets stuck and backtrace shows its
stuck in memblock.c:pa_memblock_unref() -> memblock_free()
-> pa_mutex_lock().
