I had the same problem on rocket league with that ps4 controller with no sound and i know why! It may be wrong what i say but its the best answer i could find , however the main problem is that the controller is connected to a ps4 soundbox and since your PC/laptop has a Pc/laptop soundbox the controller cant connect into the Pc/laptop soundbox! but thats just a theory no one knows what the problem really is.... just play with mouse and keyboard.
