amarok --debug output

Version:           4.5.1 (using KDE 4.6.3) 
OS:                Linux

I'm not able to play AudioCDs with Amarok. After adding the tracks to the playlist pressing "play" doesn't cause anything.

In particular in "amarok --debug", when I press "Play" I get:

What version of phonon-gstreamer are you using?

Additionally, please follow the instructions here to generate a phonon-gstreamer debug log: http://techbase.kde.org/Development/Tutorials/Debugging/Phonon

Roger, I'll do that ASAP.

amarok --debug log with phonon debug output

A run of:
amarok --debug
with:
export PHONON_DEBUG=5
export PHONON_PULSEAUDIO_DEBUG=5
export PHONON_GST_DEBUG=5
export PHONON_GST_GST_DEBUG=8

while trying to play some songs from an Audio CD with Amarok 2.5.0 on KDE 4.7.4 (Arch Linux), Phonon 4.6.0 and Phonon-gstreamer 4.5.1.

Beware, the log file uncompressed is 17MB!

Comment 4 Diego 2012-01-19 12:46:08 UTC

The attachment from comment #3 should provide all the informations required.

Comment 5 Torrie Fischer 2012-09-23 10:16:53 UTC

Phonon-GStreamer 4.6 was a substantial rewrite of the internal state handling and audiocd support. Could you please retest this with the latest version, 4.6.2?

Comment 6 Myriam Schweingruber 2013-04-13 11:36:45 UTC

Closing for lack of feedback. Please feel free to reopen if this is reproducible with the phonon-backend-gstreamer 4.6.3 or later.
