Preloading attached sound

Hello!

Also, I am just beginning. I have read lots of posts with similar problems, however, my preloader is slightly different as it is a separate file altogether.

I have attached a sound on frame 50 of my movie using ‘attach sound’.
It plays fine. On my linkage I have ticked ‘export on first frame’. When this is not ticked it does not play. So I left it ticked.

My preloader is a seperate .swf that loads the movie that has the sound.
I can tell the sound has loaded as the preloader takes a lot longer. However, when the movie has loaded and begins to play the sound just does not exist. Or it is shy and does not want to talk.

I can’t do the thing everyone is suggesting (moving sound to frame 3 and unchecking ‘export on first frame’, then modifying my preloader script) because my preloader is separate to my movie.

Do any smart flash brains have a suggestion, because I am not yet a smart flash brain. Perhaps I am a couple of brain cells at the moment. Anyway, I would be thrilled to have help in conquering this irritating problem!
