[as 2.0] load sound stores sound in movieclip?

Hello guys…

PLEASE HELP !!!

I am using 99 Movieclips and loads sounds using loadSound method.
Problem is that,even after I change the files in my sounds folder(from where I fetch sounds),the Movieclip still plays the old sound.

Does loadSound store the sound in the movieclip?.
If yes,is it possible to erase?.

Please help.

Thanks.
