So, I've been having some trouble adding new horns to the SLI Amtrak locomotives. I know how to do it, and it sort of works. The game reads that I've installed the new horn, but the sound of the horn is very high-pitched for some reason. I've tried multiple horns and it does the same thing with each one. It sounds fine when I preview them, but when I open the game and blow the horn, it just sounds like a high-pitched squeal. Has anyone else had this problem with the SLI Amtrak engines? If so, how do you fix it?
