[Flash 8] Sync sound, single frame animation

I’m working on an animation that’s all in one keyframe (all animation is done with the tween class).

How can I set sounds to play only at a certain time using actionscript? Looping is not problem, but having a sound play 5 seconds…or 10 seconds…or whatever time into the movie I can’t figure out. Mostly I just want a few sounds to play once at specific times in the movie.

Any suggestions?
