Sound issues with my flash game

Hi, I’m making a game with Edward platformer engine for Flash. But there seems to be a problem where the sounds keep repeating over and over again when you enter a teleport and go to the next frame. If someone could help me with this then I would appreciate it.

This FLA shows what I’m talking about: http://www.sendspace.com/file/yv210n (download it at the bottom of the page)
