Recently (I am new to AC, hi everyone) I modded game by adding new cars like brabham super car and stuff like that yet Lexus LFA has no sound no matter which cam I am choosing, same that Brabham , Seat Cupra car and few others.
Where is the problem? I saw few videos on YT where those cars have their engine sounds...
Help please ?
