Having problems with jet sounds in cfs2

PROBLEMS WITH JET SOUNDS IN CFS2. I have installed a couple of jets in cfs2 with no problem but some have the sound of a prop plane, regardless of what i put in the sound file or even if it is empty the plane still has the prop sound. Where can it be pulling the sound from? How can I fix this problem?
Thanks,

I don't have CFS but I imagine it's the same as FS9, you have to make the change in the CFG file.
What it's doing now is aliasing the sounds from default aircraft.

Radarman,
Im not sure what to look for or change in the cfg file to create the sound I need, any suggestions,
Thanks,
Alan

As I said I don't have the game.
This is just a guess, check these two sites and if nothing helps contact MS here. cfssdkfe@microsoft.com.
