Amarok doesn't reproduce any song, neither shows an error message. it happens even having the mp3 codecs installed Reproducible: Always Steps to Reproduce: 1.Double click in any song 2. 3.
Amarok does not play sound, this is done by Phonon. You very likely have a mixup of phonon Qt4 and Qt5 based stuff, please address this to your distribution. FWIW: Amarok git master plays sound quite fine here, so this is specific to your installation
