Description of problem: If I run the vlc client on an audio file (or video file with audio track) and then exit (either using the exit menu command or ctl-C) *before* stopping the play, then pulseaudio "freezes" giving an annoying buzzing type sound (as if the last partial note keeps replaying). This requires me to manually stop and restart the pulseaudio daemon. If I stop playing the audio/video file *before* exiting then everything is ok. This seems to be a nasty bug somewhere in the vlc-pulseaudio interface. Note that I do not get a similar problem when I ctl-c out of mplayer or any other audio player for that matter. (The half-backed implementation of pulseaudio on F8 is getting really frustrating!!!) Version-Release number of selected component (if applicable): vlc-0.8.6-d from atrpms How reproducible: 100% Steps to Reproduce: 1. Install vlc from atrpms 2. vlc <audio file> 3. Menu: File->Exit (or press ctl-c a couple of time) 4. Pulseaudio crashes! Actual results: Expected results: Additional info:
Also, there were no messages to /var/log/messages. Even running pulseaudio -vvv from the command line didn't turn up anything interesting at the time of exit
I am able to AVOID the crash by changing the "Audio output module" (under Settings->Preferences: Audio->Output modules) from "Default" (which I believe is Alsa) to "EsounD audio output" While this avoids crashes, it doesn't address the two root problems with PulseAudio: - A bad setting in a client program should not crash PulseAudio and wipe out sound for the system. There is a bug out there somewhere.... - More fundamentally, PulseAudio IMHO should never have been released into F8 when it breaks so many standard applications requiring all types of non-obvious changes to settings and workarounds.
Thanks for your report.

You will probably need to be root for that as it runs setuid. Install yum-utils package and do a debuginfo-install pulseaudio. Then connect the debugger with "gdb -p `pidof pulseaudio`" and do a "bt" More on stack traces: http://fedoraproject.org/wiki/StackTraces > (The half-backed implementation of pulseaudio on F8 is getting really > frustrating!!!)

Fortunatelly your opintion doesn't matter here. What would matter would be constructive contributions such as fixes, or bug reports (such as this one). What doesn't count as a constructive contribution is insulting developers who invest their free time and effort into making the operating system that you run happen.
This message is a reminder that Fedora 8 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 8. 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 '8'. 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 8'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 8 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
Closing due to lack of response.
