I added this to a condition on my site:
$("body").append('<embed src="Sound.wav" autostart="true" hidden="true"></embed>');
and it worked, but the page stopped accepting input after the sound played. This is for an in-house application, so I can specify which browser and version the person has to use.
Q: Why did the page stop accepting input into the text input field?
<embed>
tags appeared randomly. You should scrap the jquery.sound.js route and try something else. – Kelly
