I don't know whether I am mad or what. But since Arma 1 the rush/roar/sound of the ocean drives me crazy when I am near the coast (I also don't like that sound on TV). It is such an annoying and terrifying sound that can not be turned down without affecting other sounds. Using "enableenvironment false" is no solution since it also disables wind and birds.
A separate slider for the ocean volume would be really great.
