I have downloaded some mods off of the beam.ng website and some of them don't have and engine sounds. For example if I download a whole new mods, like new model and style it has no engine sound, i can hear the tires but not the sound of the engine. If i download a mod that is just a different version of a car that is already in the game it just uses the same sound of that car. I dont know what is causing the problem with car mods that i have downloaded but if someone could tell me how to fix or something like that, that would be great. (sorry if wording is a little weird not good with these types of things)
