      Build and run Qt 5.2.0/5.2.1 QtMultimedia AudioOutput example and try to change volume level -> nothing happens. Works fine with Qt 5.1.1.

      Could this "TODO" have something to do with this:

      qtmultimedia/src/plugins/coreaudio/coreaudiooutput.mm
      void CoreAudioOutput::setVolume(qreal volume)
{
    const qreal normalizedVolume = qBound(qreal(0.0), volume, qreal(1.0));
    m_cachedVolume = normalizedVolume;
    if (!m_isOpen) {
        return;
    }

    //TODO: actually set the output volume here
    //To set the output volume you need a handle to the mixer unit
}
