Sound area rollover

Here’s the case, hopes somebody helps me on this

I’ve made my first flash movie, and I’m happy with it.

I would like to make it neat in such way that if user goes with pointer over certain area - sound plays.

This is basically what I want - when mouse gets over black area - sound plays.

Since my movie isnt “button” Im kinda lost what to do…

So - how could I accomplish this.

One important thing is that the sound doesnt play again if mouse gets “out of the area” and then back over. Because that’s annoying.

Sound clips is 5 seconds long.

So…any help…appreciated
