Making a button play sound

Question

     Okay, i have been working on flash in school, and the school upgraded from flash MX to flash CS5, i have then gone to make my project in AS3, however, it is very diffrent from AS2
     My problem, is, all i want is a button to play a song from the libray (not from a URL on the internet like the code snippet) and my ICT teachers have no idea how to use AS3. I also need is a play, stop and pause button, and a volume control slider, i CAN do all these on AS2, i infact have it set up (but without a pause button) but, i cannot do this in AS3 and i need it done bady, can anyone explain simplay how? all guides i can find use AS2

Answer 1

Well, thank you for the help, although i havent followed it completly it has helped me get started, so far i have programed a working play and stop button, the volume slider is still beyond me, my codeing sofar is;
play_btn.addEventListener(MouseEvent.CLICK, onClickPlay);
function onClickPlay(e:MouseEvent):void{
myChannel = mySound.play();
var mySound:Sound = new MP3_1();
var myChannel:SoundChannel = new SoundChannel();
stop_btn.addEventListener(MouseEvent.CLICK, onClickStop);
function onClickStop(e:MouseEvent):void{
myChannel.stop();
Any suggestions on how to make a Slider adjust the volume levels, using a compent slider
