How to close the Sound object

Question

I'm using Flash CS3, running code in ActionScript 3.
I use the Loader class to load a child SWF file, which then
takes over the entire area on my website that is reserved for
Flash. If the user decides to stop watching the SWF file before it
is completed, he hits the "close" button within the child SWF,
ultimately causing the Loader.unload() method to be executed. So
far, so good, only the sound from the remaining portion of the SWF
file keeps playing. According to the Flash Docs for the
Loader.unload() method:
"As a best practice, before you unload a child SWF file, you
should explicitly close any streams in the child SWF file's
objects, such as LocalConnection, NetConnection, NetStream, and
Sound objects. Otherwise, audio in the child SWF file might
continue to play, even though the child SWF file was unloaded."
It then gives an example that assumes you already have access
to the Sound object, so closing the Sound object is done by:
mySound.close();
The only problem is that I have no idea how to access the
Sound object when I use the Loader.load() method. Where is this
beast? I can't seem to find anything in the documentation that
tells me how to find the Sound object after calling Loader.load().
As a temporary fix, I modified the target SWF file so that when the
"close" button is hit, it calls the "stop()" function; however,
this only stops the sound, it does not close the associated Sound
object, and I presume it continues to lurk around in memory with
nothing useful to do. (When the user hits the "close" button in the
child SWF file, it creates a "bubbling" event so that the Loader
class can call the Loader.unload() method on it.)
I've attached code for your reference.
Any help is deeply appreciated!

Ack! Looks like I hijacked this thread, sorry.
I'm doing almost exactly the same thing the OP is doing...
Loader class to load an external SWF (which is a video file FLV).
If the user hits the "close" button on the video, the video goes
away as it should but the audio continues.
I understand that I need to close any NetConnection and
NetStream objects in addition to unloading the movie. What I don't
understand is how to do that. I'm sure that it's a syntax thing I'm
just not getting right. I would just really like a more detailed
explanation of stopping NetConnections and NetStreams (but an
explanation for the not-so-actionscript-experienced LOL).
Thanks.
