Sounds are not working properly

I know it’s not a big deal but when I install a mew cam shaft the sound does not change and same with the turbos. Just seeing if anyone else is having this same issue and if there’s a fix for it. I am playing on pc and I updated all my drivers so I don’t really know what else to do

Yes it happened to me as well. LOW AF sound. and Support isnt reaching out to me and mods here didnt let me post.
