Sounds No sound in some mods

[chbmxer]

So I've installed some mods, and none of them have sounds. Also mods I've been playing for ages stopped having sounds. Can someone please explain what's going on, and how to fix it.

..did you install any sort of "sound fix" you found on Facebook?

No

does the sound work if you use the car in question with no other AI cars on track?
