[pulsesink] since upgrading plugins sound is garbled via Amarok
Last modified: 2010-06-28 15:59:13 UTC
Amarok (using the GStreamer Phonon backend) will play the first track in the playlist fine, then when it moves on to the second it becomes garbled, as if the sound is being played through an electric fan. If I restart amarok it will do this again. I think it is since my last system update which included: Updated gstreamer-ffmpeg-0.10.10-1.fc12.x86_64 Update 0.10.10-1.fc12.1.x86_64 Updated gstreamer-plugins-bad-free-0.10.18-1.fc12.x86_64 Update 0.10.19-1.fc12.x86_64 Updated gstreamer-plugins-good-0.10.22-1.fc12.x86_64 Update 0.10.23-1.fc12.x86_64
I suppose this is the same issue as https://bugzilla.redhat.com/show_bug.cgi?id=603496 ?
Looks like it!
To be clear, it's not just amarok, this seems to affect phonon in general. I get garbled/stutters on system beeps and other audio notifications as well.
My (and phonon/pulseaudio developer colin guthrie's) best guess is that this has something to do with changes in the gstreamer pulseaudio output plugin. For me, rollilng back to gstreamer-plugins-good-0.10.22 made the problem go away.
Could one of you check if this problem still exists with pulsesink from latest GIT? Also a git bisect would help to find the commit which caused this behaviour. It's quite interesting that this only happens with phonon though... where's the source of the phonon gstreamer backend? Maybe phonon is doing something different than everybody else :)
http://gitorious.org/phonon In particular, http://gitorious.org/phonon/phonon/trees/master/gstreamer I'll do some more testing (and hopefully bisecting if I have time today).
OK, confirmed problem goes away by replacing 0.10.23's /usr/lib64/gstreamer-0.10/libgstpulse.so with the copy from 0.10.22
Tested gst-plugins-good-0.10.23.2 , and it seems to fix the problem(s) reported here for me (on fedora 13 x86_64 kde-4.4.4 phonon)
That's good to hear, let's close this one then.
