Tanatos are you using a translator? If so, please get a friend to translate it better for you cause I really don't understand what you're saying. Voice should work IF windows recognizes your microphone as the default device. Voice should work if you press and hold Z. You DON'T hear your own voice when you speak. Others in the server do. If you can't hear ANYTHING regarding Voice Chat, then your Voice Volume is off via MTA Menu.
