I just reinstalled opensuse codecs for KDE to fix an issue with mplayer and now Amarok 2.3 no longer plays mp3 files (maybe others too, but I only tried MP3). In System Stettings/Multimedia the Intel HDA Digital Devices do not play a sound when I click “test” - but Analog still works.
I tried resetting device value in Yast, rebooting and reinstalling Amarok, and downgrading/reinstalling phonon but none of these has worked
