That's true. It happened with XFR on Ky National. I couldn't hear my engine when driving. All the others sound fx were ok.I could hear the others' engines but not mine. The sound doesn't drop suddenly.
It seems that the volume goes down progressively,in 2 or 3 seconds,
and then it disappears. Most of the times, it happened just before the 1st corner, in the 1st lap of a race. But i noticed it also in free practice.
Does it happen to anybody else?
