No sound in html

Hi guys,
i have my fla with this little mp3 loaded dynamically and looping:whistle:…when i publish in flash I hear the sound, but when i try to publish in explorer pressing F12 i don’t hear a sound. Also online, on my site, I can’t hear a sound. Do you know way?

This is my AS
[AS]grillisound = new Sound();
grillisound.onLoad = function() {
this.start(1, 9999);

Thanks in advance for the help
