Car sound Issues/not working in Private Multiplayer


I have problem with car sounds in private multiplayer,
in the second race on the track as the first race, sounds/ noices of my car completly turn off, but I can hear everything else (even other cars)
doesn´t matter, if I have my own car or rented one. And when I change track, the sound is working only in the first race.

Hope someone know where is problem.
