Advertisements My base Roamio outputs audio and video to a Yamaha Receiver. This decodes the DD5.1, remaps the center dialog channel to the front R&L and outputs the signals to 4 monoblock amps and an amplified subwoofer. Video is sent, again via HDMI to an HDMI multiplexer and on to Slingbox and my projector. No pops, squeals etc. Did have trouble with my previous Premiere until I replaced my old Integra receiver. Your Roamio and the Sony Tv are not getting along on HDMI. Good luck trying to convince either brand they are wrong. You just gotta find what works and go there.
