Can any one tell me how I can fix a sound problem? I have been using FSX with various add ones for some time with no problems. Now when panning inside the cockpit some of the sounds go quiet or reduced. I have a 2nd older PC running which is ok sound wise. So I have copied the sound files from the working PC to my current higher working PC. This includes the main sound folder but also the sound folders for individual aircraft. It has worked for some of the aircraft but not for others. Is there any thing else I can do. To re-install is not really an option as I have too many add-onís to delete and re-install which I am sure will add more problems.
