IE9 - mp3 not playing

Using Windows 7 and IE9, mp3 audios won't play when viewing a course from our LMS, but will play when files are published locally to HTML. As best I can tell this is only occurring on audio set to auto-start on page load. Audio set to play on a mouse click, work fine.


Toggling compatibility view does nothing. No problems using WinXP and IE8.


Anyone else experience this and find a solution other than convert audio to Flash? Oddly, when I search "IE9" on this forum, I get no search results.
