I recently am porting my Qt4.8.3 project to Qt5.2.1 on Mac. I'm having problem with QSound playing all my wav files. With Qt4.8.3 every file plays fine. But with Qt5.2.1 none plays. Strange thing is there is no error given. Tracking the status of the QSoundEffect the last status code returned is 2, meaning "Ready to Play". But it just doesn't play.
