How to make a button in one frame mute all sound/audio in the next frame?

Hello,

I'm trying to create a toggle button that allows users to switch between having music playing or not playing by clicking on a button. However I cannot find a solution that works. Is there anyway for a button to mute all sound from playing in the next frame?

I currently have a start menu whereby music plays - below is the code for that section;

Frame 1 (Main Menu)

stop();

var s:Sound = new JazzyFrenchy_Bensound();

var sc:SoundChannel = s.play();

var s_bool:Boolean = true;

PlayBtn.addEventListener(MouseEvent.CLICK,PlayBtnFrame);

function PlayBtnFrame(e:MouseEvent):void

{

  gotoAndStop(2);

}

Frame 2 (Next Menu)

MusicToggle.addEventListener(MouseEvent.CLICK, OffBtnMusic);

function OffBtnMusic(e:MouseEvent):void

{

  if(s_bool){

  sc.stop();

  } else {

  sc=s.play();

  }

  s_bool=!s_bool;

}

OptionsBackButton.addEventListener(MouseEvent.CLICK, BacktoMenu);

function BacktoMenu(e:MouseEvent):void

{

  gotoAndStop(3)

  if(s_bool){

  sc.stop();

  } else {

  sc=s.play();

  }

  s_bool=!s_bool;

}

Any responses will be greatly appreciated.

Many thanks.
