TalkPHP - Sound only works in Internet Explorer

html4strict Code:

<html>
<head>
<title>Sound Test</title>
<script language="JavaScript" type="text/javascript">


function PlaySound() {
  var sound = document.getElementById("track");
  sound.Play();
}

</script>
</head>
<body>
<h1>Sound Test</h1>
<embed id="track" src="song.mp3" width="0" height="0"
  autostart="false" enablejavascript="true"/>
  
<input type="button" value="Play the Sound"
  onClick="PlaySound()">
  
</body>
</html>

The problem with this code is that it works with IE but it doesn't work with Firefox and opera,even when I used the DoPlay() function it only works
once it does not replay
