Certainly not blaming AFM for this one, but figured I would bring it up in case anyone knows an easy answer.
I am using the Cessna 172 combined with REP and the SimAcoustics FMOD experience sound pack. Adding the AFM in to that (or possibly more accurately, adding FMOD into the AFM G5 aircraft) with REP causes the sounds to go strange). So, definitely a conflict there somewhere. Only fix seems to be uninstalling the aircraft entirely, then reinstalling, installing REP, and sticking with the default 172 sounds.
Any thoughts anyone? As soon as I find a board for SimAcoustics, I will send a note to SimAcoustics with the same to see what they say
