Personally, I find the random sound on the website really annoying, but here you go:
<audio> <source src="audio/audio.mp3"></source> <source src="audio/audio.ogg"></source> HTML5 Needed </audio> <script> var audio = $("audio")[0]; audio.play(); </script>
or something like:
$("<audio></audio>").attr({ 'src':'audio/something.mp3', 'volume':0.4, 'autoplay':'autoplay' }).appendTo("body");
Both of these examples use HTML5, but with minor modifications, you can use flash memory to play audio.
