Nfs unbound car sounds are too low or quite

The car sounds in NFS Unbound are actually really good, but they’re too low or quiet. You can barely hear the engine even though it sounds nice, which makes the cars feel less powerful and less exciting. I already maxed out the car and effects volume in the game, and even turned my speakers all the way up, but it’s still too quiet. It’d be better if the engine sound volume was boosted so you can really feel the roar while driving.
