@Zhukov211Frostbite has always had very "sketchy" audio. It sometimes works and often does not.
In BFV you could throw dynamite, turn around and detonate it without it making a sound.
Especially distance is totally off in 2042, when you hear vehicles it sounds like they are on the opposite side of the map, but in reality they are right beside you, I think the same goes for footsteps.
And footsteps above you are extremely loud, while many others are silent. Sounds from behind is just bugged in general.
The audio-system in Frostbite has some issues and while many of these are 'legacy-issues', but BF2042 is worse than BFV and BF1.
In BFV (and earlier versions), Frostbite could only mix 20 sounds at once, with 128 players that is not much...
