The JRE, the sound, or the code?

I am having a devil of a time trying to develop a new
sound format. After abandoning my earlier efforts on
the basis that I could not reconstruct the binary
representation to a usable sound, I revisited the
problem today and found my local JREs do not seem
to play the *original* sound that I am converting,
correctly.

Which leaves me to wonder whether it is the sound, the
code or the JRE that is the problem.

The code is ..
<sscce>
import java.net.URL;
import javax.sound.sampled.*;

public class LoopSound {

  public static void main(String[] args) throws Exception {
    URL url = new URL(
      "http://pscode.org/media/leftright.wav");
    Clip clip = AudioSystem.getClip();
    AudioInputStream ais = AudioSystem.
      getAudioInputStream( url );
    clip.open(ais);
    clip.loop(5);
  }
}
</sscce>

The sound is located at the URL shown above. It
was made using Java sound, is 2 seconds in duration,
stereo, and should fade between 441 Hz in one channel,
to 882 Hz in the other, and back again.

When I play it in the system default player, the Totem
Movie Player v. 2.24.3, it sounds as I expect.

Does it play OK for you?

(And as an aside) It should be loopable without any
perceptible 'click' at the loop points. Totem loops it
but has a noticeable click. Does it loop smoothly
for you?
