I need help. I own both CS 757 & 767 aircrafts, however the sound files are way opposite.  The 757 sounds are perfect!  Sound great and in accordance properly with where you sit In the VC.  However the 767 VC sounds are horribly wrong!  With the entire cabin locked up it still sounds as if you're standing on the outside of the aircraft directly underneath the APU!

The APU in the VC is horribly loud, to the extent that it's about to blow my ear drum out!!  I can't even run it now because it's way too loud.

I've tried everything!  I've tried Aircraft.cfg merges between the 75- & 76- and still nothing.  I've tried opening the Captain Sim folder in FSX and directly copying and pasting the entire Sound File from the 757 including the Sound.cfg files and placing them directly into the 767 file while deleting the old 767 sounds.  Then when I start up FSX, absolutely no change, still loud as all hell. >:(. Third, i tried moving the APU.wav files directly into iTunes and manually turn down the wav volume then placing that new .wav file in the 767/sound file and still no freakin change!  And finally I tried opening the Sound.cfg file directly in the FSX/Captain Sim/767/Sound archive, then I tried editing the APU volume from 0.2 to 0.1 and even went as low as 0.01... Then restarted FSX, and guess what... NO CHANGE!!!  Still loud as hell!!!  How The hell do I get these sound files to match directly to how the CS 757 sounds sound????

Somebody please help me!!!!! :D
