Version-Release number of selected component (if applicable): pulseaudio-0.9.16-10.test6.fc12.x86_64 How reproducible: Start up pulseaudio, it evaporates within a few seconds, after just a few sounds are played. Reverting to 0.9.16-7 works. Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:
Hmm, this is not good. Could get me the output of "pacmd ls" of the configuration you are running when this happens?
Hmm, and could you get me stack trace of this, too, please?
OK, sorry for the delay, had to wait for a time when I wasn't busy dealing with actual work.. :) Stack trace: (gdb) where #0 0x00000030f1c33675 in raise (sig=<value optimized out>) at ../nptl/sysdeps/unix/sysv/linux/raise.c:64 #1 0x00000030f1c34e55 in abort () at abort.c:92 #2 0x00007ffff78eda2f in memblock_free (b=<value optimized out>) at pulsecore/memblock.c:543 #3 pa_memblock_unref (b=<value optimized out>) at pulsecore/memblock.c:580 #4 0x00007ffff78f012d in drop_block (bq=0x659bc0, q=0x7fffe8002c40) at pulsecore/memblockq.c:207 #5 0x00007ffff78f0580 in drop_backlog (bq=0x659bc0) at pulsecore/memblockq.c:222 #6 0x00007ffff78f07e5 in pa_memblockq_drop (bq=0x659bc0, length=0) at pulsecore/memblockq.c:555 #7 0x00007ffff7da2e78 in inputs_drop (s=0x655d50, info=0x7fffed64e620, n=2, result=<value optimized out>) at pulsecore/sink.c:810 #8 0x00007ffff7da4f9f in pa_sink_render_into (s=0x655d50, target=0x7fffed650d30) at pulsecore/sink.c:1039 #9 0x00007ffff7da599f in pa_sink_render_into_full (s=0x655d50, target=0x7fffed650de0) at pulsecore/sink.c:1069 #10 0x00007fffed66f315 in mmap_write (on_timeout=<value optimized out>, polled=<value optimized out>, sleep_usec=<value optimized out>, u=<value optimized out>) at modules/alsa/alsa-sink.c:601 #11 thread_func (on_timeout=<value optimized out>, polled=<value optimized out>, sleep_usec=<value optimized out>, u=<value optimized out>) at modules/alsa/alsa-sink.c:1359 #12 0x00007ffff7904d40 in internal_thread_func (userdata=0x63f880) at pulsecore/thread-posix.c:72 #13 0x00000030f280691a in start_thread (arg=<value optimized out>) at pthread_create.c:297 #14 0x00000030f1ce0a4d in clone () at ../sysdeps/unix/sysv/linux/x86_64/clone.S:112 #15 0x0000000000000000 in ?? () (gdb) quit I've attached the output of a 'pulseaudio -vvvv' from start to crash, and the 'pacmd ls' output from both a working run, and a broken one.
Created attachment 358920 [details] output of pulseaudio -vvvv
Created attachment 358922 [details] 'pacmd ls' from working 0.9.16-7 pulseaudio
Created attachment 358924 [details] 'pacmd ls' from broken 0.9.16-10 pulseaudio
Should be fixed in 13-test7.
