Sound onMouseOver In FireFox

[getlowdogg369]

Hello everyone! This is the JavaScript code I am currently using so it plays a sound onMouseOver:
//<![CDATA[
var aySound = new Array();
aySound[0] = "sound/bleep.wav";

document.write('<BGSOUND ID="auIEContainer">')
IE = (navigator.appVersion.indexOf("MSIE")!=-1 && document.all)? 1:0;
NS = (navigator.appName=="Netscape" && navigator.plugins["LiveAudio"])? 1:0;
ver4 = IE||NS? 1:0;
onload=auPreload;

function auPreload() {
if (!ver4) return;
if (NS) auEmb = new Layer(0,window);
else {
Str = "<DIV ID='auEmb' STYLE='position:absolute;'></DIV>";
document.body.insertAdjacentHTML("BeforeEnd",Str);
}
var Str = '';
for (i=0;i<aySound.length;i++)
Str += "<EMBED SRC='"+aySound[i]+"' AUTOSTART='FALSE' HIDDEN='TRUE'>"
if (IE) auEmb.innerHTML = Str;
else {
auEmb.document.open();
auEmb.document.write(Str);
auEmb.document.close();
}
auCon = IE? document.all.auIEContainer:auEmb;
auCon.control = auCtrl;
}
function auCtrl(whSound,play) {
if (IE) this.src = play? aySound[whSound]:'';
else eval("this.document.embeds[whSound]." + (play? "play()":"stop()"))
}
function playSound(whSound) { if (window.auCon) auCon.control(whSound,true); }
function stopSound(whSound) { if (window.auCon) auCon.control(whSound,false); }
//]]>
My question is, how do I make it so it works in FireFox? As you can see, it is only preloading the sound for Internet Explorer and Netscape.
document.write('<BGSOUND ID="auIEContainer">')
IE = (navigator.appVersion.indexOf("MSIE")!=-1 && document.all)? 1:0;
NS = (navigator.appName=="Netscape" && navigator.plugins["LiveAudio"])? 1:0;
ver4 = IE||NS? 1:0;
onload=auPreload;
Any ideas?

navigator.appName=="Netscape"
The Fire Fox Browser is Netscape
if you would like to see your self view this code in Fire Fox

<script type="text/javascript">
<!--
alert(navigator.appName)
-->
</script>

You can also use this code in other browsers to see their name

Then why does this JavaScript code work in Netscape and not in FireFox? Can someone please look over the code to see if there are any errors? Thanks!
