Hi, I'm running Amarok 1.4.9.1 (using KDE 3.5.10).
Somehow I can't get an error whenever I try to load an audio file. There's a couple of errors popping up, but they all disappear except for the "no suitable demux plugin" error, which stays on the screen.
Rhythmbox is playing the files, so apparently the problem is Amarok-related.
