title: mediaelement.js not playing MP3 in Opera
body: <p>Using the sample provided with mediaelement.js (mediaelementplayer-audio.html) I am unable to play MP3 files in Opera.  It works if I navigate Opera to <a href="http://www.mediaelementjs.com" rel="nofollow">http://www.mediaelementjs.com</a> but if I try to hit the files from my localhost, it doesn't play.  The control renders correctly, but it doesn't appear to load.  I am running Opera 12.14 on Windows XP I have already tested Chrome 24, Firefox 18, IE8 (Flash fallback), and Safari 5.1.7 and only Opera is giving me an issue.  Any suggestions? </p>
