Sound On/Off with Stream event i main timeline

hi
I have a (very) long flash movie (flashMXpro, Player7) with a number of stream sounds (in the same layer) (sync’ed with animation over 3-5000 frames at 36fps)

I want to have a On/Off button for the sound in general, but every solution i can find uses MC’s and i can’t do that.

HOW do i make a simple “all sound off”/“all sound on” [without calling MC’s or restarting the movie] - so the action can not be associated with a specific sound because the user may stop sound in one stream (lets say frame 100) and turn it on again in frame 400 (another sound) - theres only one sound playing at a time.
