Hi. I'm new to this site and hope someone can give me advice on what to do. My Denon AVR has 3 HDMI input slots. I have Time Warner cable and the coax goes from the wall to a Time Warner tuning adapter which is connected to my TiVo Premiere 4, which is then connected to my Denon AVR. A while ago, the audio in the lower input slot of the Denon quit (video is OK). A couple of days ago, the middle slot's audio also quit. The top one still transmits both audio and video. When I want to watch regular TV I have to plug into the top HDMI slot and when I want to play my Plsystation 3 or 4 I have to unplug the TiVo HDMI cord so I can plug in my PS3 or 4 into the top slot, which is a real pain. Is there anything I can do to get the other 2 HDMI inputs to work correctly?
