Sound control help needed MX question

hi everyone I am working on one project where I stuck on one little sound question:
I have two scenes; loading and scene1 where my main movie is located :O), so
in my preloading scene I have a basic 15 frames- animation where the sound is in the first frame the animation ends so quick but sound is still playing.
what I wanna do is to make animation play until the sound ends playing and then jump to scene1. its kinda hard to explain if u need a better explanation plz let me know.

thx so much
