Weird audio streaming problem

Question

I am dynamicly loading in an external mp3 to use for audio
for a flash animation. I've done this several times (its a series).
On this most recent flash movie however, the audio is being loaded
in externally but instead of playing normally, it is sped up to
about twice the speed. This is making the person sound like a
chipmunk.
I usually just copy the .fla from the last movie I worked
on, so all the code is the same. Any ideas on why it is doing this
to my audio? Its funny... but I don't think they want it that way.
some code:
//The audio file to be played
var playAudioFile:String = "Audio/walruspoem.mp3";
//Loads in a single audio file
var loadAudio:Function = function(audioFile:String):Void{
//Determine the loader showing how far things have loaded
var loader:MovieClip = audioLoader_mc;
loader.loading_txt.text = "Loading Audio";

Answer 1

Thank you very much for your assistance.
The audio drops out at a new slide. I have done some
additional investigating and found that:
1. When I use the "Preview" function to review the project,
there is no problem. However,
2. When I use the "Publish" function, and publish the project
as a "Standalone" file with file type = Windows executable, and the
Zip files check box un-checked, the audio problem occurs.
3. When I publish it with the same settings, but I ALSO check
the Zip files checkbox, I don't have the audio problem.
So it almost seems like it is a bug in the Publish function.
I am using a free trial version, but I have ordered and expect to
receive a paid-for version today. I will install that software and
see if the problem is still present.
