So I have my new Denon 2313ci and loving it so far. My issue is with the audio return channel or "arc". My tv is Cec compatible, Sony xbr6, the handshake occurs when I turn the tv on to oth hd, triggers avr to "tv audio" and notes on tv screen "audio switched to external speakers" but can't get sound from avr. Nothing. Been through as many settings as I can find on both devices. Tv recognizes denon in "compatible devices" in hdmi control menu.... After a call to Denon, they advised to turn hdmi control off on tv but leave on in avr settings, still no dice. I am certain the plethora of knowledge here holds the helpful answer.
This forum has been very helpful in my quest for ht and amazing audio. Thanks for all contributors.
