Playing the same sound many times

if(!soundOn) return true;

Clip snd=getSound(name);

if(snd==null){
Debug.err("! SoundBank.playSound() Sound '"+name+"' not present!");
return false;
}

if(snd.isRunning()){
snd.stop();
}
snd.setMicrosecondPosition(0);
snd.start();

I would suggest that you load your clip to a byte array and then use AudioSystem.getLine to get a new line for each clip. Here is a short example how to play audio.wav 32 times simultaneously (i.e. 32 polyphony):
