AM GTE, BMW GTE sound problem at high revs

There is one problem - sound becomes irregular as the revs increase. Not completely, it just becomes "tattered".
Tried different numbers of channels, but the problem remains. How can I reset the sound settings? Or the settings of these particular cars?

 

Hello?

 

it sounded perfectly normal until you got to the end of the lap. It looked & sounded like you were hitting the rev limiter but the sound occured again after the chicane when you had not yet reached the limit. Could be the sound rpm/limit does not match the engine rpm limit.

 

Yeah, it's like the rev don't match. It's only on the GTE BMW\AM, all other content is fine.
