(PC) No engine sound from my car mulitplayer

So for the last 2 or so weeks whenever iv played multiplayer (all i play these days) every 2nd or so race my engine noise is not conning through. Sounds like its still stuck in the menu.

System is
I7
1070gtx
960evo m.2
16g ram

This is not an issue with my setup. Why cant turn 10 fix the game instead of making more problems. Also want split screen on pc.
