Mp3s playback broken in newest flash player

Question

Hi
I've been developing flash sites for many years. Many of them
are dynamic.
Recently since upgrading the Flash Player (9,0,115,0
installed) in my Firefox browser, a flash site I've built for my
university work has broken. But the same site works fine in IE with
Version 9,0,60,235 installed.
Mp3s that are loaded dynamically from a separate folder do
not play. They worked fine before christmas, they played fine; the
swf has not changed; the files have not moved; the code is the
same. They simply do not play.
Have there been changes to the flash player security that
would disable playing mp3s that exist on the same server?
Do I now need a crossdomain file for my own mp3s on my own
server?
I feel strongly that Adobe must begin to respect and ensure
backward compatibility or risk losing its customers. I will have no
interest in developing in Flash if my sites could all suddenly
collapse. (Another example of dead flash files due to change in
code:

All help appreciated, David

Hi Tiago,
Very basic setup.
Since I want the capability of using the page locally (not
always on a server with php) I generate a list of mps and write
that to a txt file using php once.
Then each time page loads, read in the mp3s.txt file and
assign a property "mp3" to a button-movieclip, then use a hitarea
rectangle mc within that button-mc to call on the first press of
the rect button :
this._parent.son.loadSound("mp3s/"+this._parent.mp3, true);
Since the buttons appear, i know the txt file is being read
correctly....
Since the sound plays in IE browser with the other version of
player i know the basic setup is correct.
all suggestions welcome,
david
