PlayStation Sound Problems On Br146.2, Br143, Br185.2/.5

Dear Developers every time when I drive with these trains the sound sounds get wired after they get to a speed above 100km/h and the sound when the br146.2 gets from 0-60km/h sounds wired, not like TSW2020, it would be very nice if you would fix it.
Have a nice day and best regards Nicholas
