Will sound files in 2004 work in fsx? Right now I don't have any but I can get some and I have a plane that I would like to change to the sound it had in 2004. Will it work?Don

Yes, the sounds should work fine.I've had trouble with a couple of aircraft I've transferred from FS9 to FSX though, where the sound seems to distort when changing outside camera views, which eventually leads to FSX and the whole PC freezing.
