I'm struggling to play audio files using Qt 5.11.3 and the QMediaPayer class. There is no sound output when playing either .mp3 or .wav files. I had some success to play a wav file using QSound class.

I have also set QT_DEBUG_PLUGINS to 1 but I can't see any clear error.

My goal is to be able to play .mp3 files using the Qt implementation.

  • Have you solved it yet? if yes, can you please share your solution with us. I got the same issue and don't know what to do now. – AlexATV Jun 18 at 16:06

This will sound dumb, but the only thing missing was gstreamer1.0-pulseaudio. I missed to notice that one of the components needed pulseaudio, so I think that the pulseaudio install broke my Qt.
