Amarok playback not working on karmic Ubuntu (NOT Kubuntu)

[Thomas Horsten]

Binary package hint: amarok

When I start Amarok it shows a popup with: "Phonon: KDE's Multimedia Library - The audio playback device Playback/recording through the PulseAudio sound server does not work. Falling back to default."

Then when I add an MP3 file to the play list and I hit Play, nothing happens (no sound plays), but on the terminal I started it from it prints "(<unknown>:30002): GStreamer-CRITICAL **: gst_element_make_from_uri: assertion `gst_uri_is_valid (uri)' failed"

I have ubuntu-restricted-extras installed. Playback of the same MP3 file works in Rhythmbox player and also Totem Movie Player.

I tried starting amarok with --debug and the output is below. I added "--------------------------------------------------------" before I clicked "Play".

th@hydra:~$ amarok --debug

[Flavio Tordini (zarlino)]

I can confirm this. The bug is not Amarok specific, it applies to any Phonon app using the Gstreamer backend. IMHO this has to be marked CRITICAL.
