var iframe = $("<iframe/>").load(function () {
    alert("loaded");
}).attr({
    src: "http://code.jquery.com/jquery-1.4.2.min.js"
}).appendTo($("#thediv"));

Note that I'm loading a JavaScript file, not an audio file, so that might make a difference.

Solution 3:

Maybe you call some Firebug internal function, like console.log(), somewhere? In that case, Firefox will threw an exception which can stop the execution if Firebug is not active.
