Sound audio ticks issue : car list and conditions when ticks occur [currently list in progress]

There is an issue related to audio that I ve noticed the very minute I ve driven the catheram during the early access in 2020, there are little ticks with diverse intensity for certain cars, a lot of them actually, its a audio loop tick related to driving at specific speeds and rev meter numbers, I should presume that its a game issue, not on my part, Project Cars 2 dont have those audio loop ticks issues for any of their cars. I hope I can give some help to devs by doing those long tests who are really time consuming but on the end good for the game.

Im listing all the cars of the game who even ticks when general car volume is at 20 and mark them full audio when its flawless regardless of the audio settings :
to sum up : *** Ticks on all cases ** No ticks on genral car volume 0 * No ticks at all.
Edit : no need to change general car volume at 0 since it only happened for the BTW GTR after test driving 30+ cars, basically it solved that issue for just one car.
