Sound control problems [renamed]

I’m creating a presentation.

It is set up as follows

I have an fla that contains several scenes.

Each scene has a different voiceover.

In this presentation I would like to have a control
panel that allows you to go back and forth between
scenes, stop and start as well.

The problem I am having is that I cannot get the audio
to cooperate. When I click the the next or previous
buttons the voiceovers over lap. i tried adding a
stopAllSounds action but that stops the sounds
entirely even when in the new scene.

I would like to be in a scene that is running
(animation, sound, etc.) and be able to pause/play the
action and sound as well as jump to a new scene or
previous scene and have the scene and all it’s
elements start up.

Any advice, suggestions would be greatly appreciated.
