on arch linux 64bit fully updated, I can't play audio cds in amarok, kscd with phonon-vlc backend.
clementine, based on gstreamer, can. vlc can as well.
amarok crashes if media is played from menu.
when launched from device-noifier widget, sometimes it sees an empty audio cd, sometimes it sees nothing.
kscd displays cd content, but doesn't play it.
kscd cl output errors:
[0x302c948] main services discovery error: no suitable services discovery module
Object::connect: No such signal Phonon::VLC::MediaObject::angleChanged(int)
Object::connect: No such signal Phonon::VLC::MediaObject::availableAnglesChanged(int)
