The File Browser in Amarok uses the Phonon::BackendCapabilities::availableMimeTypes() method to show the available media files. Currently, it doesn't show any *.ogg files, while those show up correctly with the xine backend. Using the vlc backend from git of today, Amarok 2.3.1-git of today, KDE SC 4.4.92 on Kubuntu 10.04
Checking with the xine backend definition, adding << QLatin1String("audio/x-vorbis+ogg") to the list in src/vlc/backend.cpp solves the problem for me.
Created attachment 49313 [details] patch to show ogg files The attached patch should solve this problem
Created attachment 49314 [details] better patch This patch should be better :)

Reassigning to the new bugzilla product for better bug tracing of the various backends. Sorry for the noise.
