I am fairly new to flash cs6, and this may be a newb question, but here it goes.

I just received a flash .fla file at work, which I didn't create. It requires me to replace its audio with some new audio and sync its old animations to follow the new audio. The main timeline is just the audio and an action script layer. The animations are somehow being called up by the action script from the library. The movie clip with the animations in it has no sound in it.

How do you work with something like this? Is there a way to preview the movie clip, yet have the sound from the main timeline come through? I realize I could drop the sound file into the movie clip, but is that the most efficient way of doing this?

Thanks
