I've not figured out how to translate a call like this
simpleU.getViewer().createAudioDevice();
for use with a non-simple VirtualUniverse.
I did spent some time working with this approach:
AudioEngine3D a3d = new AudioEngine3D(physicalEnvironment);
physicalEnvironment.setAudioDevice(a3d);
a3d.initialize();
but was unable to get it to work. The device is created and attached
to the universe, but I couldn't get any audio.
whereas the following works, at least with certain MediaContainer types
HeadspaceMixer mixer = new HeadspaceMixer(physicalEnvironment);
mixer.initialize();
For completeness, the sample code I pointed to before:
http://clearwater.com.au/java/J3DSound6.java
contains both implementations, with the AudioEngine3D method
switched out in favour of the HeadSpaceMixer.

Alan, we've used:
AudioDevice audioDev = simpleU.getViewer().createAudioDevice();
in our 3D worlds but we did have unpredictable problems (locking up
after a random amount of time, often HOURS later) but can't specifically
identify sound as the exact problem but it clearly increased the
frequency of crashing. This was back on Java 3D 1.2, so far with Java
3D 1.3 we have done almost no work with sound.
