I want to be able to play an alarm sound using Javascript in a browser window, preferably with the requirement for any browser plugins (Quicktime/Flash). I have been experimenting with the tag and the new Audio object in Javascript, but results are mixed:

As you can see, there is no variant that works on all browsers.

Do I miss a trick that is more cross-browser compatible?

This is my code:

// mp3 with Audio object
var snd = new Audio("/sounds/beep.mp3");snd.play();

// wav with Audio object
var snd = new Audio("/sounds/beep.wav");snd.play();

// mp3 with EMBED tag
$("#alarmsound").empty().append
('<embed src="/sounds/beep.mp3" autostart="true" loop="false" '+
 'volume="100" hidden="true" width="1" height="1" />');

// wav with EMBED tag
$("#alarmsound").empty().append
('<embed src="/sounds/beep.wav" autostart="true" loop="false" '+
 'volume="100" hidden="true" width="1" height="1" />');

}
