All CONNECTED VIA HDMI and have bee working fine until I had The Arris DCX3600 installed. Lost CEC and ARC to all devices. Already had LG replace HDMI board to no success. I have no sound from TV apps. There are other topics about this but NO TWC solution or response. Why isn't there a fix without me having to break HDMI pins?
