So, every time I import a sound into Flash, It's alright, until I stream it, and then the sound quality degrades. When I press enter (play movie), the quality is the same, but when I press ctrl+enter (test movie), the quality degrades.

Thanks DiPi. Worked for me. Please lock this. And, did you get my message?
