Video to flash

I'm trying to make a flash file out of a video clip I have. I import the video with flash as an object to the library and i'm able to put it into the video with ease. But the problem is there is no sound. How do I get the sound from the video to come with it when I import to the flash file? Thanks.

Split the video prior to import as video and sound.  Import both respectively and sync them.  Profit.
