jquery - JavaScript: Changing src-attribute of a embed-tag - Stack Overflow

You should remove the embed element and reinject it with the new src parameter set.
embed like object and similar are two elements which, due do their special uses (video, audio, flash, activex, ...), in some browsers are handled differently from a normal DOM element. Thus changing the src attribute might not trigger the action you expect.
The best thing is to remove the existing embed object an reinsert it. If you write some kind of wrapper function with the src attribute as parameter this should be easy

I was also facing same issue when I want to change "src"-attribute of "embed" element, so what I did, is given below:

var parent = $('embed#audio_file').parent();
var newElement = "<embed scr='new src' id='audio_file'>";

$('embed#audio_file').remove();
parent.append(newElement);

And this will work fine in my application.

Conclusion: - You need to first remove the embed element and then you have to reinsert it with change in src.
