On this video
, there are three links to the sounds for the F16, F14, and FA18. I just tested one link and it seemed okay (the link).
No idea if there are sounds for any other jet though.
Edit: Actually, it seems those pbo include the sounds AND the Plane. Might be the reason you don't find them anywhere (i mean if that had been done without the author's consent. Just a thought though, i don't know anything about this).
