You have 2 "autoplay" in the command
Code:
<noscript>
<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=9,0,0,0" width="500" height="72" id="mp3player5a" align="middle">
<param name="allowScriptAccess" value="sameDomain" />
<param name="allowFullScreen" value="false" />
<param name="movie" value="mp3player5a.swf" />
<param name="quality" value="high" />
<param name="bgcolor" value="#000000" />
<embed src="mp3player5a.swf" quality="high" bgcolor="#000000" width="500" height="72" name="mp3player5a" align="middle" allowScriptAccess="sameDomain" allowFullScreen="false" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" add auto_play="true" autoplay="yes" autoplay="true" />
</object>
</noscript>
Pull the one that says "true" there should only be 1 of those and you want it to say "yes". If that doesn't work I have no clue what needs to b done.
This code has my mind hurting. I would have written it a little different.
