have searched forum for this issue but cant see it: i simply cant hear the opponent engines at all. i used to get stuttering sound from the car ahead, but now i get absolutely no sound from the opponent. settings are all ok, even when i reduce player vol to zero i get nothing from the other cars. i get nothing in car, trackside or in replay. its fine on AC, PC2 etc, but i have always had this problem on rf2. i've never messed about with the settings so i havent broken a line in the .plr for example. its baffling, any suggestions?
Even if you haven't messed around in the plr file, I'd try to back it up, delete it and make the game create a new one. It might be old and the game has changed a lot lately. In fact, I'd delete the entire userdata folder.
