You will need to call `SoundChannel.stop()` anyway, just record the position once you receive pause signal, and then once you need to play the sound from that position again, call `play()`. I don't understand why you don't want to use `stop()` function. You need it, period. — Vesper, Apr 09 '15 at 16:53

If you want to play seconds 21-40 of a 60 second sound(which is what I think you are trying to do), then when you play the sound sound.play(21) then try adding an ENTER_FRAME event listener and checking the position of the channel to stop it at 40...

    private var stopPosition:int = 40000;
    private var pause:int = 21000; // set to 21 secs for example in code

    protected function p1_clickHandler(event:MouseEvent):void{
        if(p1.label=="PLAY"){
            sc=snd.play(pause);
            sc.soundTransform=st;
            p1.label="PAUSE";
            addEventListener(Event.ENTER_FRAME, checkPosition);
        } else {
            pause= sc.position; 
            stopTheSound();
        }
    }

    private function checkPosition(event:Event):void{
         if(sc.position >= stopPosition){
              stopTheSound();
         }
    }

    private function stopTheSound():void{
         sc.stop();
         p1.label="PLAY";
         removeEventListener(Event.ENTER_FRAME, checkPosition);
    }
