Ever since I have the White Noise update there is no longer microphone symbols in the scoreboard and the voice chat is no longer functioning. Fix this.
Hey Coppperneck,
One thing we'd definitely recommend is checking your HDMI cable and at most, flipping it around. So the side that plugs into your TV is now plugged into your Xbox and vice-versa. Outside of this, we'd recommend uninstalling and reinstalling the game. Give these couple steps a shot and let us know how it fairs.
