Hi,

I’m creating a flash game where all of my library symbols, including my sounds, are contained in an assets movieclip on the second frame. The first frame is a preloader and it works fine, however, when I uncheck “export in first frame” for my mp3 sounds in the library I get the error:

1046: Type was not found or was not a compile-time constant: mySound

I have all of the sounds on seperate layers and they all have class names defined. I’ve seen quite a few threads that bring up this issue, but none that solve it. So, how do you preload a hefty mp3 from your library without exporting it on the first frame?
