Randomly play sounds

I’m wanting to create a flash movie with the sole purpose of randomly playing sounds.

I’ve set up a supermarket forum and want to play sounds at random intervals to mimic the “tanoy” announcments in supermarkets.

There will be 10-15 recordings which must play at random times, and in random amounts. Say one time a user may log in and hear just one recording, then the next time they log in they may hear 3 or 4.

Is this possiable?
