      Description



      Name: dkR10031 Date: 12/16/2002



      The J2SE 1.4 Java Sound implementation reports a most mixers independently
      of how many soundcards are available. The following test was run on linux
      box without soundcards:
      ------------------------------------------------------------------------
      import javax.sound.sampled.*;

      public class MyMusic{
          public static void main(String args[]){
              Mixer.Info[] mixerInfo = AudioSystem.getMixerInfo();
              for(int i=0; i<mixerInfo.length; i++){
                  System.out.println("Mixer #"+i+":"+mixerInfo[i]);
              }
          }
      }
      ----------------------------------- Logs -------------------------------
      Mixer #0:Java Sound Audio Engine, version 1.0
      Mixer #1:Linux,dev/dsp,multi threaded, version Unknown Version

      This behavior is ambiguos - if there is NO
      soundcard installed, how can the implementation
      possibly report a format?
