I posted this some time back but wondered if anyone else has this issue In cab sounds on the class 20 and 47s introduced with Blackpool DLC have heavily distorted sound on acelleration that is so bad the locos are as good as unplayable. Normal sounds when on an external view with no problem but when in the cab driving postion and particularly when acellerating hard are extremely distorted/clipping very similar to wind effects on unshielded microphones outdoors. I changed my amp and speakers and still the same issue, this occured when the otherwise excellent Blackpool branches was released and extends into other routes ie the class 20 on its orgional route that used to be ok now isn't. I have tried uninstalling Blackpool dlc and the class 20 and reinstalling the class 20 only but didn't fix the issue. With the 47 seems to be the later ones only ie the preserved one is ok.
