Audio Mix options have generally been terrible in previous Halo titles. It’s ridiculous that in 2015 Halo still does not have seperate audio sliders. Players should not have to use 3rd party hardware in order to change basic audio options.
I have a really good home theater system that I prefer to use anyway when setting up my sound for games and what not but, not everyone has this so I think it’s a good thing to have in game for those who do not.
