crackily sound on swf format

Hi,

Whenever I export my animations to .swf format the sound is all crackily and muffled, but when I do it in any other format its fine and I have tried using MP3, WAV and AIFF files

I am using TBS 5 and would consider updating it if would fix the problem?

Is it possible for you to send a sample audio file for us to test in TBS 5?
You can send it to support@toonboom.com with your TBS version (Help/Toon Boom Studio - About), along with your operating system and your username.
