I can't for my life get any sound of my python app in Sailfish. The song seems to play just fine and it shows the right progress and all but no sound in the speakers. And no errors at all. On desktop, harmattan and sailfish emulator it works just fine. But on the jp it's not. And gst-launch works just fine so it's not a problem with my phone. Could the sound be disabled from python somehow? Permissions or something else?
