fine, and here is backtrace for the abort I was getting sometimes for the same use case (music over phone) any clue how to avoid this first ? #0 0x407f42ec in raise () from /lib/libc.so.6 #1 0x407f9b04 in abort () from /lib/libc.so.6 #2 0x4011dc34 in signal_handler (sig=<value optimized out>, si=<value optimized out>, data=<value optimized out>) at pulsecore/memtrap.c:103 #3 <signal handler called> #4 0x4005ccc4 in pa_mix (streams=0x422958ec, nstreams=2, data=0x41a938c0, length=<value optimized out>, spec=0x42297d5c, volume=0x40078608, mute=<value optimized out>) at pulsecore/sample-util.c:247 #5 0x40078608 in pa_sink_render_into (s=0x33c28, target=0x42297cc4) at pulsecore/sink.c:1031 #6 0x40078b90 in pa_sink_render_into_full (s=0x33c28, target=0x42297d5c) at pulsecore/sink.c:1075 #7 0x419ad08c in mmap_write (userdata=<value optimized out>) at modules/alsa/alsa-sink.c:605 #8 thread_func (userdata=<value optimized out>) at modules/alsa/alsa-sink.c:1480 #9 0x4012ee1c in internal_thread_func (userdata=0x331d0) at pulsecore/thread-posix.c:72 #10 0x407ada90 in start_thread () from /lib/libpthread.so.0 #11 0x408a0fb8 in clone () from /lib/libc.so.6 gst logs when starting "music" stream from gst-launch: ERROR: from element /GstPlayBin2:playbin20/<div id=":2m4"> GstPlaySink:playsink0/GstBin:abin/GstBin:bin0/GstPulseSink:pulsesink0: pa_stream_write() failed: Connection terminated Additional debug info: pulsesink.c(1587): gst_pulseringbuffer_commit (): /GstPlayBin2:playbin20/GstPlaySink:playsink0/GstBin:abin/GstBin:bin0/GstPulseSink:pulsesink0 Execution ended after 75439452 ns.

We need to match up PA streams with mpris2 clients. I think this should be solvable but I've not looked too deeply at mpris stuff to know the finer details. 2. Even with this module, the problem of a media player which uses the PA_STREAM_START_CORKED flag would still be there I think. :( <div><div></div><div class="h5"> Col -- Colin Guthrie gmane(at)<a href="http://colin.guthr.ie" target="_blank">colin.guthr.ie</a> <a href="http://colin.guthr.ie/" target="_blank">http://colin.guthr.ie/</a> Day Job: Tribalogic Limited [<a href="http://www.tribalogic.net/" target="_blank">http://www.tribalogic.net/</a>] Open Source: Mageia Contributor [<a href="http://www.mageia.org/" target="_blank">http://www.mageia.org/</a>] PulseAudio Hacker [<a href="http://www.pulseaudio.org/" target="_blank">http://www.pulseaudio.org/</a>] Trac Hacker [<a href="http://trac.edgewall.org/" target="_blank">http://trac.edgewall.org/</a>] _______________________________________________ pulseaudio-discuss mailing list <a href="mailto:pulseaudio-discuss@lists.freedesktop.org">pulseaudio-discuss@lists.freedesktop.org</a> <a href="http://lists.freedesktop.org/mailman/listinfo/pulseaudio-discuss" target="_blank">http://lists.freedesktop.org/mailman/listinfo/pulseaudio-discuss</a> </div></div></blockquote></div>
