I only have two devices from xfinity. The internet device is CGM4140COM and is connected via coax in a room. I have the xi6 in the living room. There are no filters, amplifiers, or splitters. On a side note, I have a 2019 Samsung q70 and I downloaded the xfinity stream app. I get 5.1 on live programming while using the app. Thanks again for your help.
