Preload sounds

I’m having an issue where I make a new instance of a sound file in my code. However when doing so it then has to load this sound file even before the preloader can display. One work around I’ve used before is to make a swf that just loads the entire second swf. This ensures that everything will be loaded at the start.

However, if possible I would like to avoid this. I know that if i place the sounds on the stage (after frame 1) the preloader works fine, but at that point Im unsure how to access them within my as3 files.

So if anyone knows how to ensure the sounds do not get loaded before the preloader starts and I am still able to control them via actionscript i would be very great full
