Description of problem: When playing audio through pulseaudio while using the jack-sink using some programs, pulseaudio segfaults. paplay always causes a segfault, while mplayer -ao pulse never does. Some programs that play through the alsa plug do not cause a problem (firefox) and some do (xbmc). Version-Release number of selected component (if applicable): pulseaudio-module-jack-0.9.15-17.fc11.i586 pulseaudio-0.9.15-17.fc11.i586 jack-audio-connection-kit-0.116.1-5.fc11.i586 How reproducible: Always Steps to Reproduce: 1. Add the following lines to /etc/pulse/default.pa: .ifexists module-jack-sink.so .nofail load-module module-jack-sink sink_name=puff-jack-output channels=6 connect=false .fail .endif I added these lines after the RTP section. 2. Launch jackd: jackd -R -dalsa -djack51 -r48000 -n4 -o6 -P -p1024 & 3. Relaunch the pulseaudio daemon 4. paplay /usr/share/sounds/warning.wav Actual results: The pulseaudio daemon dies after the sound is played. The following message appears in the system log: pulseaudio[32189]: segfault at b7423949 ip 0090075a sp b26fcf1c error 4 in libjack.so.0.0.28[8f8000+11000] Expected results: The pulseaudio daemon does not segfault after the sound is played. Additional info: Running pulseaudio from the terminal and attempting the above gives: $ pulseaudio W: pid.c: Stale PID file, overwriting. W: module-jack-sink.c: JACK error >zombified - calling shutdown handler< N: alsa-source.c: Increasing wakeup watermark to 30.00 ms Segmentation fault Running in verbose mode seems to prevent the crash, but still causes an Abort.

That's actually not a segfault, but instead some internal thing in Jack I believe. Please provide a stacktrace of this abort!

I tested this again with pulseaudio-0.9.21-5.fc12.i686. I don't get the same segfault that I got before. However, things still don't work correctly. I get the message "JACK error >zombified - calling shutdown handler<". However, jackd continues running and accepting new connections. Are you asserting that this is an error in jack?

This continues to be a problem in Fedora 13 with: pulseaudio-0.9.21-6.fc13.i686 pulseaudio-module-jack-0.9.21-6.fc13.i686 jack-audio-connection-kit-0.118.0-1.fc13.i686
*** Bug 584087 has been marked as a duplicate of this bug. ***
The bug still persist in Fedora 14. I cant run PulseAudio with jack sink at all, it crashes on initialization. Can it be a kind of permissions issue? It starts normally for root user (e.g. #sudo pulseaudio).
I just ran across this longstanding bug because I'm getting a similar(/same?) segfault in pulseaudio when running atop jackd. I've gotten a workaround which is sufficient for the timebeing, but in case it helps/connects-with this bug, I'll describe my specific case. I'm running *el6. I just bought a shiny new lexicon alpha usb audio device. I never had this problem with the same config with the onboard intel hda, or brief experiments with a turtle beach audio amigo usb audio (though it has a horrible driver bug that introduces filterable noise on the line-in). Finally, what is especially interesting, is that this only happens if I run jackd with a limited capture device. i.e. -Chw:1,1 instead of -Chw:1. Now, why would I want to do -Chw:1,1 in the first place? If I don't do that (*and* there is a usb2.0 hub between the lexicon and the host), jackd fails to start, with syslog messages about failing to allocate sufficient usb bus bandwidth. Now, maybe -Chw:1,1 wouldn't even do what I intended it to as a workaround (i.e. hoping to get 1 usable input on the device, not needing all 4 (stereo inputs 1/2). But it does get jackd to start, and audio output working fine (for native jack apps, since I can't get pulseaudio started) But I'm giving up on that attempt to use it with the hub, since getting full capabilities by plugging it into 1 of 2 of my hosts usb ports, barely works out (my other dozen devices chained off the other of the laptops skimpy 2 ports). Anyway, not knowing the code, but making an educated guess, I wonder if pulse is confused by such a situation. finally, and perhaps least importantly, I also noticed some (pipes?) from jack under /dev/shm, one with the name jack_0 and another jack_ack_0. I'm guessing thats all fine and expected and not evidence of some string munging bug.
This message is a reminder that Fedora 13 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 13. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '13'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 13's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 13 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 13 changed to end-of-life (EOL) status on 2011-06-25. Fedora 13 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
