Description of problem: Both 'Test' buttons in the 'Audio Conferencing' section of The capture 'Test' button in gnome-sound-properties shows this error after a few seconds: Failed to construct test pipeline for 'gconfaudiosrc ! audioconvert ! audioresample ! gconfaudiosink profile=chat' Version-Release number of selected component (if applicable): alsa-plugins-pulseaudio-1.0.14-3.fc8 pulseaudio-libs-0.9.7-0.13.svn20070925.fc8 pulseaudio-utils-0.9.7-0.13.svn20070925.fc8 pulseaudio-0.9.7-0.13.svn20070925.fc8 pulseaudio-libs-glib2-0.9.7-0.13.svn20070925.fc8 pulseaudio-module-gconf-0.9.7-0.13.svn20070925.fc8 pulseaudio-module-x11-0.9.7-0.13.svn20070925.fc8 gstreamer-plugins-pulse-0.9.5-0.4.svn20070924.fc8 pulseaudio-esound-compat-0.9.7-0.13.svn20070925.fc8
Right now it's just the Test button for Capture that doesn't work. Here's what happens: 1. I click the button. 2. The button stays depressed for a few seconds. 3. A dialog pops up with this error message: "Failed to construct test pipeline for 'gconfaudiosrc ! audioconvert ! audioresample ! gconfaudiosink profile=chat'" 4. A horrible reverberating feedback sound begins to play. Usually closing the dialog stops it, but sometimes not. 5. Any sound played while the feedback is audible feeds into it. 6. Muting the input device in pavucontrol stops the feedback sound, but unmuting it allows it to return.
I can confirm that the Test button for capture doesn't work when Pulseaudio is selected, but the error i get is a bit differnt: gconfaudiosrc ! audioconvert ! audioresample ! gconfaudiosink profile=chat: Failed to connect stream: OK
On the cmdline, I see sound-properties-Message: Error running pipeline 'gconfaudiosrc ! audioconvert ! audioresample ! gconfaudiosink profile=chat': Failed to connect stream: OK [pulsesrc.c(427): gst_pulsesrc_prepare (): /pipeline0/gconfaudiosrc0/bin1/pulsesrc0]
Hmm, I am not even sure if that can ever work, because the pipeline is missing a delay element. At least in older GST this did not work properly unless you had some very special buffering set up. I will check this out and look what the current status of this is.
Should not be a blocker, according to Lennart. Also pretty much unfixable. Downgrading to target.
Lennart, is it only the Test button that won't work, or are you saying sound capture is broken?
Based on the date this bug was created, it appears to have been reported during the development of Fedora 8. In order to refocus our efforts as a project we are changing the version of this bug to '8'. If this bug still exists in rawhide, please change the version back to rawhide. (If you're unable to change the bug's version, add a comment to the bug and someone will change it for you.) Thanks for your help and we apologize for the interruption. The process we're following is outlined here: http://fedoraproject.org/wiki/BugZappers/F9CleanUp We will be following the process here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping to ensure this doesn't happen again.
Yeah, sound capture still doesn't work at all even in rawhide. Let alone the capplet.
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
Fedora 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 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.
