<DL>
<DD>Code to load sound data into a channel of device mixer
 Load sound as one or mores sample into the Java Sound Mixer:
   a) as either a STREAM or CLIP based on whether cached is enabled
   b) positional and directional sounds use three samples per
      sound
 Overriden method from AudioEngine3D.

 Sound type determines if this is a Background, Point or Cone
 sound source and thus the JSXxxxSample object type
 Call JSXxxxxSample.loadSample()
 If no error
     Get the next free index in the samples list.
     Store a reference to JSXxxxSample object in samples list.
