If you log on the sound indicator works properly but I had a friend lof on after me in the same area and now my sound indicator does not work when I move but lights up and copies his movements.. So in other words my indicator goes off his movements and not mine for if he doesn't move and I move mine shows no sound but if I stand still and he moves it shows sound. but if I log out and back in it happens to him and mine is fine, so works properly for the last person logged in.
