[JAVA3D] JavaSoundMixer using Java 3D 1.3 Beta

[David Refsland]

Hello -

 

I have attempted to upgrade my 3D API to version 1.3 Beta. When I run my code, code that works with the previous API version, I get a runtime error when initializing my JavaSoundMixer. Does anybody know what is going on?

 

JavaSoundMixer javaSoundMixer = new JavaSoundMixer(environment);
     javaSoundMixer.initialize();
  if( javaSoundMixer != null )
  {
   boolean status = javaSoundMixer.initialize();
   if( status )
   {
    System.out.println( "Sound Mixer Initialized.. " );
   }
   else
   {
    System.out.println( "AudioEngine Not Created properly" );
   }
  }
  else
  {
   System.out.println( "AudioEngine Not Created properly" );
  }

the initialize line gets the following runtime error, though it does compile.

Thank you for any help you may have on this subject.
