The file PETE.avi contains both audio and video
I will quickly demonstrate playback using the GLMediaPlayer examples of this file.

#Audio only playback using GLMediaPlayer

Getting the GLMediaPlayer to connect with the AudioSystem3D will require some API changes inside the JOGL and JOAL project.
At a minimum, AudioSystem3D and GLMediaPlayers ALAudioSink has to use the same ALCcontext in order for the ALAudoSink "Source" to be positioned inside the AudioSystem3D.
This will require an enhancement bug-report.
