I am having a problem getting a background sound to play in the web browser, Mozilla.

Actually what I would like to do is a sound should be played auotmatically once a web page is loaded without clicking on anything to play it.

I used the <embed> and <noembed> tag to play sound in IE and for other web browsers like MAC OS X 10.4 Tiger, Mozilla, Netscape. But for Mozilla, no sound is played when I opened the HTML file. Hope someone could me give me some idea of how to play a sound in Mozilla.

These are the HTML coding:

HTML Code:
<embed src="Testing.mp3" autostart=true hidden=true>
<noembed><bgsound src="Testing.mp3"></noembed>
Thanks in advance
