Sound Overlapping.. how to fix?

I have a set of 10 links, every link takes me to a especific keyframe, in the keyframe i have a sound that plays when the keyframe plays.. but i have a big problem here.. if a hit link1 that goes to frame 10 the sound begins normally and the sound is about 10 seconds length.. but if i hit inmediattly link5 it goes to frame 300 and a diferent sound begins, and it overlaps with the previous sound from the frame 10..

So my question is How do i stop the previous sound?... not alway i hit link1 and then link 5... i mean that i need to know which sound is being played for stoppin it and begin with the newsound..

Thanks in advanced!

use sound objects.

look in the ActionScript dictionary under Help in Flash. they have some examples that might be a solution to your sound overlapping problem.
