No sound from motors in split screen mode!!!😤

There is no sound from the motors in split screen mode, then shocks and brake give well and sometimes split screen before starting the race appears the regressive cutoff of 3,2,1, starts the race but a little later round of 3,2,1, gets confused and gets in the place of the map in half a race, I do ?, is a fault happens all or is only in me and I have to re-download?:cold_sweat::cold_sweat::cold_sweat::cold_sweat::sob:
