Preloader - blank page, shows up too short

1

I have a simple preloader that has to preload a movie with attached sound.
This sound is “exported for AS” on first frame. Problem:
preloader does not show up at the beggining of the movie, instead i have a blank page, and then a second only of preloader , and then movie and sound start to play…

Could you please tell me how to fix it? is there sth about that sound into a first frame?

I use that kind of code for attached sound:

x = new Sound();
x.attachSound(“music1”);
x.start(0, 5);
