Prevent audio files overlapping

i developing elearning module in flash cs5 using actionscript 3.

on frames audio file plays, , timeline moves next frame.

in background of each frame 4 buttons user can click jump different section of course.

 

the problem having when user clicks jump different section, timeline jumps; after short delay timeframes starts jumping between old frame , new frame , playing both audio clips.  suspect problem occurring if audio file has not loaded when user clicks button; first time using audio in flash wrong.

what change code when user clicks button jump somewhere else, code says stop loading audio , stop playing audio, , jump new frame. 

 

here relevant sections of code have on layer 1, frame 1:

import flash.media.soundmixer;

// event listeners
mcwhenlarge.addeventlistener(mouseevent.click, when);
mcwhatlarge.addeventlistener(mouseevent.click, what);

// event handlers

function when(event:mouseevent):void
{
      flash.media.soundmixer.stopall();
     gotoandplay(7):
}
function what(event:mouseevent):void
{
      gotoandplay(2);
      flash.media.soundmixer.stopall();
}

 

layer 1 of subsequent frames looks this:

 

mcwhen1.addeventlistener(mouseevent.click, when);
mcwhen1.buttonmode = true;

 

and layer 2 of frames looks this:

 

import flash.net.urlrequest;
import flash.media.sound;
import flash.events.event;

var soundreq1:urlrequest = new urlrequest("recording1.mp3");
var sound1:sound = new sound();
sound1.load(soundreq1);

sound1.addeventlistener(event.complete, oncomplete1);

function oncomplete1(event:event):void
{
      sound1.play();
     settimeout(gotoandstop, 2000, 3);
}

 

any can give me stop bug appreciated.

would using gotoandstop() commands instead of gotoandplay() commands far not staying @ intended frames move to? (or there frames have play when arrive?)

 

look using soundchannel class controlling sound.  consider doing have 1 sound instance redefine move along timeline, assigning new sound @ each frame.
