ActionScript 3.0 :: Get A Handle On Embedded Sound Files?

From the Sound Class information, it says to use the SoundMixer Class to handle embedded Sound Files.  I have two sound files embedded, that I have setup in 2 separate layers, starting at frame one in the main timeline.  I needed to do this so I could see the wave files, and coordinate text with the waves.  I do not want to load these files into the .swf file at runtime using URLRequest.  How do I get a handle on those as they exist, to make each controllable by separate volume and mute controls for each sound?
 
This will be a challenging question, because, "it can't be done" doesn't work for me.  I managed to create a way to use an external classfile to control the main timeline, the ROOT timeline, without having to create a sub movie to root.  I can use my component to call play(); as though it were in code in a frame.  But it isn't, it's in an external classfile.  I passed root to the classfile and told the classfile to think of it as a movieclip - that put the handle on it.  I tried similar way with root as a Sound, but that isn't detailed enough - I need to get a handle on the frame that contains the embedded sound file.  I embedded, attached it, using the properties view for the frame.
 
I've attached, or whatever you want to call it, these sound files to a frame, and this frame is or should be attached to the layer I've created.  So, under the assumption that the ROOT has everything attached to it in some manner (it is after all the foundation for the COM), the stage of the root contains the visual components, so ROOT has to have the layer objects attached to it, which should have the frame objects attached to the layers.  I have two layers that each have a .wav file attached to frame one.  Somehow Flash keeps track of that - I want to know how Flash does it so I can read what flash reads.
