Issues with Loading Audio

Hi all. I’m having a really weird issue loading in two audio clips. I have used the following steps in many other cases and it has always worked, so I was surprised to see this happen with my LAST two clips I need to insert into my flash module. Anyway, here is the process I go through:

  1. Take audio from video file in Final Cut Pro
  2. Export to AIFF
  3. Burn to CD using iTunes
  4. Import to iTunes as MP3
  5. Insert MP3 file into flash module using the following actionscript:

var my_sound:Sound = new Sound();
my_sound.loadSound("audio/testSound.mp3", true);
my_sound.start();

The audio file is within the audio folder and true is set to stream the audio file. Yes, this has worked, and continues to work for me on 99% of my attempts, however with 2 audio clips I get really squeaky, tinny sounding audio. When I go and play the audio file on its own, using iTunes or WMP, it sounds just fine. How can this be?? Is this a bug? Any thoughts?? Thanks for any help, I’m at a lost!
