This all occurs in slow motion as the TV slowly powers up. It's the switching of the AVR's input to TV AUDIO that drives me nuts. So I've now disabled HDMI CEC and run a TOSLINK cable from the TV to the AVR for the rare times when I may actually need TV AUDIO on my AVR. So much for ARC. So much for HDMI CEC. Pfft!
So, I guess another required step is activating "HDMI CEC" on the TV:
1. Make sure your HDMI cable is "HDMI version 1.4-compliant".
2. Make sure one end of your HDMI cable is attached to the "HDMI 1" input on the Vizio E601i-A3 TV (that is the port that supports ARC).
3. Make sure the other end of your HDMI cable is attached to the HDMI output on the Onkyo NR 509 receiver (that is the port that supports ARC), and that the receiver is set to the "TV/CD" input.
4. On the Vizio TV, activate "HDMI CEC".
5. On your Onkyo receiver, set "HDMI Ctrl (RIHD)" to "On".
6. Turn off both the TV and the receiver, then turn them both back on.
If the automated input switching in that setup proves overly annoying, then go with the second option of just hooking up an optical audio (TOSLINK) cable between the TV and the receiver.
My receiver from 2004 does not support ARC (it doesn't even have HDMI), but I don't intend to replace something that works just fine. I have all of my devices hooked up to the TV and then only use the optical output from the TV to my receiver (the TV does the switching rather than the receiver in my setup). I use a Harmony remote to automate the process.
