Simple Sample for BackgroundSound

Question

Hi,
I only want to add a simple BackgroundSound to my scene, but it does not work! I get no error but I get no sound, too! Has anyone a simple example for me which shows how it works or can someone tell me what's wrong with my code? Here is my code:
MediaContainer mediaContainer = new MediaContainer();
try {
mediaContainer.setURLObject(new URL("File:///c:/demo.wav"));
catch (MalformedURLException e) {
System.out.println(e.toString());
BackgroundSound sound = new BackgroundSound();
BoundingSphere soundBounds = new BoundingSphere(new Point3d(0.0,0.0,0.0), 1000.0);
sound.setSchedulingBounds(soundBounds);
sound.setSoundData(mediaContainer);
sound.setLoop(-1);
sound.setEnable(true);
objTrans.addChild(sound);
objTrans is a TransformGroup. I add it to the Root-BranchGraph. I do this in the createSceneGraph()-Method.
Greetings
Alex

cough declare the audio device first cough :D
SimpleUniverse u = new SimpleUniverse(my_canvas_3D);
AudioDevice audioDev = u.getViewer().createAudioDevice();
