    Description

      If I play Music with the Phonon::MediaObject-Class, even the audio-playback costs 100% of CPU usage. Look at the Music-Player Example delivered with Qt. It also uses waaay to much CPU.
      I attached my System-Profiler-Report and the Class which plays the audio and holds the MediaObject and the AudioOutput-Class.
