Sound keeps repeating

Hi there

I´m doing a flash work for university and i´m having a few problems with it.

The problem i have is related to ambient sound i want to put in a scene. I already did this in a past project and it was very easy but i´m having a problem with it.

I create a layer for the sound and choose a sound in the library, and then in the layer properties i choose that sound and choose Loop. When i export the movie the sound keeps repeating itself and i don´t know where that came from:diss:

Did i do anything wrong? I already tried with other sounds too but they keep repeating themselves. I also tried the repeat option and put a value of 999 but the problem persists.
