Turning the voice down to 0 does not shut them all up!
Same with me. Even with all audio sliders at O, there's still faint voice and fx.
Supposedly that's the echo effect you get in caves, etc. that's being triggered somewhere and never being cleared. The only place I can think of where you'd get an echo before entering town is the tutorial dungeon?
Whatever, +1 for me too, I can't talk to npcs near other people because I can't focus on the dialogue. I love the voices, I just can't stand to hear them say the same thing thirteen times consecutively. It's exactly like a broken record.
