I am having an issue where my Vizio E601i-A3 TV and Sony STR-DH520 AVR aren't getting along.(A quick search didn't present an obvious answer... but perhaps one of you can help.)
To make a long story short, when the TV turns on, it wakes up the AVR using CEC (a feature I want), but then 2-seconds later the AVR flips into ARC mode ("TV" mode [button 5 on the Sony remote]).
However, I am not using the TV in a mode where ARC is needed (for example, I'm not
using Vizio's Netflix client). All I want to do is watch TiVo (which comes into the TV through HDMI 1 (via the AVR).
This means I have to manually switch the AVR back to the HDMI 1 (press "BD/DVD" [button 1 on the Sony remote) to get TiVo's audio. Very annoying.
I want CEC enabled (for the TV to turn on the AVR) as well as System Audio Control (so I can adjust the AVR volume from the TV or TiVo remote). This way I can use one or two remotes (TV or TiVo) to do just about anything I want. It also allows me to use the pass-thru function should I want to watch TV after powering the AVR off (late at night, etc.)
The AVR inputs are TiVO (HDMI 1), Apple TV (HDMI 2) and PS3 (HDMI 3).
I've got HDMI output of the AVR going into HDMI 1 of the TV.
As I suggested above, the TV has CEC and System Audio Control enabled.
The AVR has Control for HDMI (CTRL.HDMI) enabled.
It seems this is an issue with the Vizio... since it is the one that issues the ARC signal.
I called Vizio tech support and Sony tech support... but both are pointing the finger at one another.
Vizio says, "The AVR isn't processing the TV's CEC or ARC commands properly."
Sony says, "The TV is sending ARC commands to the AVR when it shouldn't."
