[flexcoders] embed source mp3 : unsupported sample rate

[chrisnoeflex]

hi,

I try to execute following line of codes, to import an mp3 :

[Embed(source="music/cl1.mp3")]
            [Bindable]
public var Song1:Class;
public var mySong1:SoundAsset = new Song1() as SoundAsset;
mySong1.play();

But then my flex builder gives me the error :
'unsupported sampling rate (32000Hz)'

So i can't compile.
What is wrong here. Can't i imported just any kind of mp3 ?
plz help.....

grtz,
Chris.
