Starting and stopping sound AS3 - actionscript-3

Question

I'm trying to get a sound thats on the timeline to stop and play when i push the buttons. And there is also a animation on that timeline that should stop and play to. I cant get the code that im using to work. I get errors
Del1, Layer 'actions', Frame 1, Line 16 1061: Call to a possibly undefined method play through a reference with static type flash.media:SoundChannel.
Del1, Layer 'actions', Frame 1, Line 10 1120: Access of undefined property fireworks.
I'm new to this I have no idea how to fix the errors and get the buttons to work.
here is the entire code
import flash.events.MouseEvent;
import flash.media.Sound;
import flash.media.SoundChannel;
PlayButton.addEventListener(MouseEvent.CLICK, playbutton);
NextButton.addEventListener(MouseEvent.CLICK, nextbutton);
StopButton.addEventListener(MouseEvent.CLICK, stopbutton);
var mySound:Sound = new fireworks.wav();
var myChannel:SoundChannel = new SoundChannel();
myChannel = mySound.play();
function playbutton(event:MouseEvent):void
{
myChannel.play();
play();
}
function stopbutton(event:MouseEvent):void
{
stop();
myChannel.stop();
}
function nextbutton(event:MouseEvent):void
{
gotoAndPlay(1, "Del2");
}

Your first error: You cannot call play() on a SoundChannel
Although you can always stop() your myChannel object, you can not as simply play it. See the section titled Pausing a Sound in this tutorial for information on the functionality that you are trying to build. Essentially, when you pause your song, you need to remember that location in the song, and then call myChannel = mySound.play(thatLocation); whenever you want to resume.
Your second error: The syntax on adding your song file needs to be changed a bit
If the song file is somewhere outside of Flash, like in a folder -
var mySound:Sound = new Sound();
mySound.load(new URLRequest("fireworks.wav"));
mySound.play();
If the song file is loaded into your Flash library -
var mySound:Sound = new CustomSongNameHere();
mySound.play();
But for this case, you need to find the song in your Flash library, right-click it, select Linkage, check Export for ActionScript and change the Class field to CustomSongNameHere or whatever you use in your code.
