Stop all sounds as3? Help

[COLOR=#333333][FONT=Helvetica Neue]When the game starts. I have toggle button. I can play a sound or stop sound. When i play the sound, of course its not muted so even if i go to the next page. I can reason out that the sounds will still play.

[COLOR=#333333][FONT=Helvetica Neue]But if i press the no sound,so it means it must be muted… on the first screen, the sound stops. But when I go the next frames and to others. The sounds are playing. The sound on the starting screen[/FONT][/COLOR]
[COLOR=#333333][FONT=Helvetica Neue]was like [/FONT][/COLOR]
[COLOR=#333333][FONT=Helvetica Neue]var test:Sound = new NameOfSound();[/FONT][/COLOR]
