Sorry guys... this is my mess :(
Im going to try and get ffmpeg to handle audio playback ( at least for linux )
and Im going to implement it nicly along side BASS, in TAudio_ffMpeg ( where I can )

initialization
  singleton_MusicFFMpeg := TAudio_ffMpeg.create();

  writeln( 'UAudio_Bass - Register Playback' );
  AudioManager.add( IAudioPlayback( singleton_MusicFFMpeg ) );

finalization
  AudioManager.Remove( IAudioPlayback( singleton_MusicFFMpeg ) );


end.
