Sound ON/OFF with different scenes

i’m working on a flash intro which has more than 10 scenes.

in the first scene i need to add a sound which plays once the intro started

the problem i’m facing when the intro moves to the second scene till the last one i cant control the on/off sound from these secenes

i tried many scripts from all around the web but with no use, can anyone please guide me to any clue that allows my music to play on the whole intro with on/off button to control from all scenes
