Audio will not play with AS 3

Hi,  I'm using Adobe Flash CC 2015 and I have an issue that is driving me mad. I've used the old code from a working file (which apparently works in the container) but when I run it on my computer, it won't run properly when published. It plays the file, but the audio keeps looping over itself. It does not call for looping anywhere in the file properties. Here is my code:

import flash.events.MouseEvent;

import flash.events.Event;

stop();

var myChannel:SoundChannel = new SoundChannel();

this.addEventListener(Event.ENTER_FRAME, listenMe);

next_btn.addEventListener(MouseEvent.CLICK, clickNext);

prev_btn.addEventListener(MouseEvent.CLICK, clickPrev);

function clickNext(e:MouseEvent):void {

    myChannel.stop();

    gotoAndStop(currentFrame+1);

}

function clickPrev(e:MouseEvent):void {

    myChannel.stop();

    gotoAndStop(currentFrame-1);

}

function listenMe(e:Event) {

    if (currentFrame == 1) {

var mySound:Sound = new Sound();

var myChannel:SoundChannel = new SoundChannel();

mySound.load(new URLRequest("audio_1.mp3"));

myChannel = mySound.play();

        prev_btn.visible = false;

        stop();

    } else {

var mySound:Sound = new Sound();

var myChannel:SoundChannel = new SoundChannel();

mySound.load(new URLRequest("audio_2.mp3"));

myChannel = mySound.play();

        prev_btn.visible = true;

    }

    if (currentFrame == totalFrames) {

var mySound:Sound = new Sound();

var myChannel:SoundChannel = new SoundChannel();

mySound.load(new URLRequest("audio_3.mp3"));

myChannel = mySound.play();       

        next_btn.visible = false;

    } else {

        next_btn.visible = true;

    }

}

I know there is some repetitive code, but its in the original file that I'm updating and it apparently works, but not on my computer. I'm using a MAC Book Pro but running Windows 10 on it. Not sure if that is causing the problem or not. but other files seem to be running just fine.

Any help would be appreciated as I haven't used Flash in over a year.

Correct answer kglad

i'm assuming there's something visual on each timeline frame that makes it important for your project to change frames (otherwise, there's superfluous code).  use:

import flash.events.MouseEvent;

import flash.events.Event;

stop();

var myChannel:SoundChannel;

var mySound:Sound=new Sound();

////////////// this.addEventListener(Event.ENTER_FRAME, listenMe);  comment-out this line

listenMe();

prev_btn.visible=false;

next_btn.addEventListener(MouseEvent.CLICK, clickNext);

prev_btn.addEventListener(MouseEvent.CLICK, clickPrev);

function clickNext(e:MouseEvent):void {

nextFrame();

listenMe();

}

function clickPrev(e:MouseEvent):void {

prevFrame();

listenMe();

}

function listenMe():void {

mySound.load(new URLRequest('audio_'+this.currentFrame+'.mp3'));

myChannel=mySound.play();  // i don't see where you use myChannel, but if you need it, this is where it should be assigned

prev_btn.visible=next_btn.visible=true;

    if (currentFrame == 1) {

        prev_btn.visible = false;

    } else  if (currentFrame == totalFrames) {    

        next_btn.visible = false;

    }

}

(p.s when using the adobe forums, please mark helpful/correct responses, if there are any.)

you're calling listenMe repeatedly!  what do you expect to happen other than a excruciating audio mess?

in addition, myChannel is local to listenMe so you can't use it to stop your sound in clickNext or clickPrev.

remove that enterframe loop, call listenMe when you want to play a sound and retest.

    Thanks! Its been a while since I've used Flash... This is what i have now:

    import flash.events.MouseEvent;

    import flash.events.Event;

    stop();

    var myChannel:SoundChannel = new SoundChannel();

    this.addEventListener(Event.ENTER_FRAME, listenMe);

    next_btn.addEventListener(MouseEvent.CLICK, clickNext);

    prev_btn.addEventListener(MouseEvent.CLICK, clickPrev);

    function clickNext(e:MouseEvent):void {

        gotoAndStop(currentFrame+1);

    }

    function clickPrev(e:MouseEvent):void {

        gotoAndStop(currentFrame-1);

    }

    function listenMe(e:Event):void {

    var mySound:Sound = new Sound();

    var myChannel:SoundChannel = new SoundChannel();

        if (currentFrame == 1) {

    mySound.load(new URLRequest("audio_1.mp3"));

    mySound.play();

            prev_btn.visible = false;

            stop();

        } else {

    mySound.load(new URLRequest("audio_2.mp3"));

    mySound.play();

            prev_btn.visible = true;       

        }

        if (currentFrame == totalFrames) {    

    mySound.load(new URLRequest("audio_3.mp3"));

    mySound.play();       

            next_btn.visible = false;

        } else {

            next_btn.visible = true;

            this.removeEventListener(Event.ENTER_FRAME, listenMe);

        }

    }

    It isn't looping anymore, I appreciate your help. I now have an issue where only the first audio will play. Have I missed something you mentioned?

    you should have:

    import flash.events.MouseEvent;

    import flash.events.Event;

    stop();

    var myChannel:SoundChannel;

    var mySound:Sound=new Sound();

    listenMe();

    prev_btn.visible=false;

    next_btn.addEventListener(MouseEvent.CLICK, clickNext);

    prev_btn.addEventListener(MouseEvent.CLICK, clickPrev);

    function clickNext(e:MouseEvent):void {

    nextFrame();

    listenMe();

    }

    function clickPrev(e:MouseEvent):void {

    prevFrame();

    listenMe();

    }

    function listenMe():void {

    var C:Class=Class(getDefinitionByName("Audio_"+this.currentFrame);

    mySound=new C();

    myChannel=mySound.play()

    prev_btn.visible=next_btn.visible=true;

        if (currentFrame == 1) {

            prev_btn.visible = false;

        } else  if (currentFrame == totalFrames) {   

            next_btn.visible = false;

        }

    }


    Awesome, yes, not sure what i had incorrect put into place, but its now working properly. Do I also need to add mySound.stop(); to stop the other sounds from playing at the same time once you've clicked on the next/prev buttons? They load when clicking on the buttons but the previous audio files continue.
