Title: MS IE9 reports html5 support for M4A but then fails

This fix works around the known issue in MSIE 9 where M4A files are reported as supported by the browser but calling setMedia fails.

I added code to detect M4a and MSIE9 and force the canPlay flag to false in this case, so flash kicks in if it is one of your solutions.
