Thanks to a little lesson from Chris, I figured out what I needed to 
do.  The basic gist of it is:

.sound someSound "mySound.wav"

Gets declared directly under the .flash container somewhere.  Then, in 
an actionscript block the following is needed:

soundObj = new Sound();
soundObj.attachSound("someSound");
soundObj.start(0, 0); //first parameter lets you start n seconds from 
the beginning of the sound, second parameter tells how many times to loop

After that, I can control it as needed.
