Simple Sound

I’ve looked in the forums and I can’t find anything on this - I think it’s because it’s so simple.

I want to play some sound effects at certain moments in my time line. How do I do this with actionsript? I don’t want to attach it to any buttons, just simply when the movie reaches this point, to play a sound effect once.

What’s best? Do I import the sound files and just put them on the timeline? I think this looses quality though.

Thanx in advance.
