How can I remove a child swf and stop all sounds when parent closes?

Question

Hi All,
I am new to actionscript 3 and trying to learn as I go. The problem I am having is the following:
I have a carousel of images that load an external swf movie with a FLVPlayback component on it. The problem is that when the external swf unloads the sound of the FLVPlayback component continues to play. I am using a carousel component I found online to load the images and each image loads an external swf file. here is the code for it.
import com.carousel.DegreeCarousel;
import com.carousel.data.CarouselDO;
import com.carousel.data.AngleDO;
import com.carousel.data.ItemDO;
// DEFINING THE CAROUSEL OBJECT
var carouselSettings:CarouselDO = new CarouselDO();
carouselSettings.radiusX = 300;
carouselSettings.radiusY = 0;
carouselSettings.fov = 50;
carouselSettings.transitionTime = 1;
carouselSettings.ease = "easeInOutQuint";
carouselSettings.useToolTip = 0;
carouselSettings.useBlur = 1;
carouselSettings.maxBlur = 8;
carouselSettings.reflectionAlpha = 0.2;
// DEFINING ANGLES SETTINGS
var angleSettings_arr:Array = new Array();
angleSettings_arr[0] = new AngleDO({angle:0,alpha:1,scale:0.5});
angleSettings_arr[1] = new AngleDO({angle:90,alpha:1,scale:1});
angleSettings_arr[2] = new AngleDO({angle:180,alpha:1,scale:0.5});
// DEFINING THE ITEMS
var prefix = "content/thumbs/"
var galleryItems:Array = new Array();
galleryItems[0] = new ItemDO({thumb:prefix + "image_1.jpg", content:prefix + "swf1.swf", contentType: "flash"});
galleryItems[1] = new ItemDO({thumb:prefix + "image_2.jpg", content:prefix + "swf1.swf", contentType: "flash"});
galleryItems[2] = new ItemDO({thumb:prefix + "image_3.jpg", content:prefix + "swf1.swf", contentType: "flash"});
// PLACING THE CAROUSEL TO STAGE
var carousel:DegreeCarousel = new DegreeCarousel(carouselSettings,angleSettings_arr,galleryItems);
carousel.x = stage.stageWidth * .5;
carousel.y = stage.stageHeight * .5;
this.addChild(carousel);   
// KEYBOARD NAVIGATION
// KEYBOARD EVENTS
stage.addEventListener(KeyboardEvent.KEY_DOWN, keyDownHandler);   
function keyDownHandler(e:KeyboardEvent):void
    // left
    if(e.keyCode == 37)
        carousel.left(1);
    // right
    if(e.keyCode == 39)
        carousel.right(1);
    // top
    if(e.keyCode == 38)
        carousel.prevCycle();
    // Down
    if(e.keyCode == 40)
        carousel.nextCycle();
    // Space
    if(e.keyCode == 32)
The external movie loads fine. Then the external swf calls for a second swf containing a video. This is the code that is used to load the swf:
import flash.net.URLRequest;
import flash.display.Loader;
import flash.events.Event;
import flash.display.MovieClip;
import flash.events.MouseEvent;
var myVideo:URLRequest = new URLRequest("myvideo.swf");
var video:Loader = new Loader();
video.load(myVideo);
this.addChild(video);
When the carousel unloads, it unloads both movies but the sound keeps on playing.
Is there any way to stop the sound from keep playing?
Thank you very much!!

You want to stop the audio from playing and also downloading more video/audio if it is still downloading when you go to a new keyframe where the video display/component or mp3 player is removed from the stage because it's keyframe ended or do not exist anymore but you still hear the audio.
Add an event listener to your video playback component that calls a function when the flash player tries to remove the video plaer from the stage that stops the netstream or at least stops/pauses the video playback.

//sample NetConnection and NetStream classes when the video player is removed from the stage tell the NetStream to stop playing or downloading the content with .close();
var connection:NetConnection = new NetConnection();
connection.connect(null);
var stream:NetStream = new NetStream(connection);
addEventListener(Event.REMOVED_FROM_STAGE, videoRemovedFromStage);
function videoRemovedFromStage(e:Event){
   stream.close();
