I'm not sure why, but I no longer hear any engine sounds when I look in the cockpit straight ahead or 45 degrees to the left or right. Am I missing sound files? I haven't touched them. The problem exists for these aircraft:

YP-80
F-84G's
F-86A-5
MiG-15(bis)

I do, however, hear them for the rest of the aircraft in game.
