Flash buton to both start and stop music

Hi,

I currently have a project with two buttons to play and stop a music track, however I wish to have just one button to both start and stop the music but without the problem of playing a new channel over another creating an echo effect, I think this will need a Boolean and an ‘if statement’ to check if the sound is on or off however I have not manage to get any working. N.B. I may be way over complicating things in my second lot of code from an online tutorial.

I have this code for the two buttons:

import flash.events.MouseEvent;
stop();
var mySound:Sound = new Sound();
var myChannel:SoundChannel = new SoundChannel();
var lastPosition:Number = 0;
mySound.load(new URLRequest("Welcome_to_the_Jungle.mp3"));

Play1.addEventListener(MouseEvent.CLICK, onClickPlay);

function onClickPlay(e:MouseEvent):void{
myChannel = mySound.play(lastPosition);
}

Stop1.addEventListener(MouseEvent.CLICK, onClickStop);

function onClickStop(e:MouseEvent):void{
myChannel.stop();
}


This uses a Play1 and Stop1 button but i would like to have just one on/off button.


I have been trying to get this code to work from an online tutorial:

import flash.media.Sound;
import flash.media.SoundChannel;

var soundOn:Boolean = true; //music is ON when we start
var myMusic:TitleMusic = new TitleMusic(new URLRequest("Welcome_to_the_Jungle.mp3"));
var myChannel:SoundChannel = myMusic.play(0,1000); // endless loop, in effect
var myTransform:SoundTransform;

PlayStop.addEventListener(MouseEvent.CLICK,toggleSound);
PlayStop.buttonMode = true;
PlayStop.mouseChildren = false;


function toggleSound(e:MouseEvent)
{
    if(soundOn)
    {
        // turn sound off
        myTransform = new SoundTransform();
        myTransform.volume = 0; // silent
        myChannel.soundTransform = myTransform;
        soundOn = false;
        PlayStop.myButtonText.text = "click to turn sound ON";
    }
    else // sound is off
    {
        // turn sound on
        myTransform = new SoundTransform();
        myTransform.volume = 1; // full volume
        myChannel.soundTransform = myTransform;
        soundOn = true;
        PlayStop.myButtonText.text = "click to turn sound OFF";
    }
   
}

However I keep getting errors such as:

1046: Type was not found or was not a compile-time constant: TitleMusic.


Thank for any help
