You can load your sound at level +9 and your buttons at level +1

This is the script to load a movie in a higher level :
Put that script on the buttons at your main movie level 0

on (release) {
loadMovieNum("yourexternalmovie.swf",1);
}


BUT sometimes that gives you a problem :

When the site works fine on your computer but it doesn't work on someone else his computer, this may be the cause :

You have probably embedded your main movie in a html file. Often it is embedded in the index.html file.
Click on CTRL H in swishmax (copy HTML to clipboard) and paste it into your index.html file. Paste that code over the already existing embedded code for your movie. So infact update your html file with the most recent code for your movie.

And the problem should be solved.

The problem is here that alot of them have embedded the main movie to the index.html file once. Then they are changing the movie and they don't update the embedded code in their HTML file anymore, which cause unpredictable errors.

Feel free to ask.

Cheers,
