On my Denon 4700 receiver, the inputs for the multi-zone are analog via RCA cables. My main zone is connected to the X-1 box via HDMI but the analog out does not appear to work on the X-1 box. I know that some devices disable the analog out if the HDMI is used. Is this true for the X-1 box as well? Mine is an Arris MX011ANM. If that is the case, is there a workaround to get the X-1 audio to my Zone 2?
