Okay, got a Denon avr-1613 at a stupid price, have a Vizio E320-A0 with HDMI ARC, a pair of huge retro speakers, and Time Warner is my cable provider.
Here's the flux. I first connected TW cable direct to Vizio TV, then HDMI (Hi speed with ethernet) cable from Vizio ARC to Denon ACR plugs. Left settings a default. Nothing pic, no sound. Changed some input settings but no go.
Then, I ran TW cable direct to set top box, ran same HDMI cable from TW box (btw no ARC) to Denon HDMI ARC and all is good. Why?
My concern is that I'm moving to a apt building soon that includes in rent internet and HD cable service. There are no set top boxes just an outlet in the wall to run the cable wire from. So I will run from wall to my Vizio and HDMI to Denon and it should work?
Trust I've made myself coherent.
