Playing sounds in LMS

Would anyone know the best method for linking sound clips in an LMS? I’ve just started working with this system and I’ve heard of sound clips not working before my time.

The method I’ve always used was having separate .swf files that contain one sound file each. Then to play, pause, stop, I would load each .swf into a blank movie clip or a level.

To my understanding, the LMS is always one level down ( _root does not work at all ).

Here’s the method that we currently use in the first frame of the main time line, actions layer:
register = new Sound();
register.attachSound(“cash”);
register.start(myMusicPosition,0);

register2 = new Sound();
register2.attachSound(“money”);
register2.start(myMusicPosition,0);

Any thoughts?!?
