The engine is driven through the example's UI class CAudioPlayingAppUi. The engine has member pointer of CmdaAudioPlayerUtility and has different separate methods for different functionalities like PlayL() for playing a song which in turn calls Play() of CmdaAudioPlayerUtility . The engine also implements callback functions of the MMdaAudioPlayerCallback interface.
