Jens Struwe posted a link as a comment, it will help you with the duplicateMovieClip problem.

When you start playing a sound with mySound.play() it returns a SoundChannel-object, grab a reference to it and then use mySoundChannel.stop() to stop the playback. Also when you stop the sound playback, use var myStopPosition:Number = mySoundChannel.position to find out where you stopped. Then pass that position to mySound.play(myStopPosition) when you want to resume playback.
