Sound drops if you change camera to "door" position (external)

[dis0nored]

Hello, I love listening to the wagons and locomotive moving across the rail and rail joints, they are pretty nice so far. I did however note that if you change the camera to the one where you are either standing at th door of the wagon or rear of the car all the way back, the sound volume drops drastically which ruins the experience. It should be as loud as if you were in 3rd person view close to the wheels bottom layer of the wagon whilst it's in motion. More opinions may be need it but I am sure this is a bug.
