Right now, in the audio settings, we only have the ability to adjust master volume and effects volume. I think it would be an amazing feature to be able to adjust different sounds individually. For example, vehicles are SO loud. So when you are driving with your audio up, the vehicle is basically the only thing you can hear. Or if you are playing a PVP server, you may want to turn up footstep sounds and/or gun sounds and turn down animals so you can hear better if someone is near you.
So having the ability to adjust all of the individual sounds would be a great addition.
