Didn't mean to imply a separate cable would be necessary.
What the other poster was saying was that an HDMI 1.4 cable that supports audio both ways (can send audio in both directions) would work sending audio back to the AVR from the Elite. Therefore the Netflix sound would be sent back to the receiver from the Elite if you have the right cable and you change system setting in the Elite to send audio back. You would not have to listen to Netflix through the sets internal speakers which compared to a sound system is quite lame.
Now I can be completely misunderstanding what he said but thats what I got out of it.
You got it right. Before HDMI 1.4, if you wanted to send audio and video to the TV, but also wanted the TV to be able to send audio back, you needed 2 cables... an HDMI to carry stuff to the TV, and some kind of audio cable (optical, whatever) to carry sound back.
With audio return channel, a single HDMI cable will do it. What I found from researching all the HDMI 1.4 stuff was basically this... there's 3 major things in HDMI 1.4
Something that says it is HDMI 1.4 compliant is saying it can handle the handshake for any of the 4 major formats by which 3D signals get transmitted between components. Back in HDMI 1.3 you weren't guaranteed that a brand of TV could understand the 3D signal from a given source. If both are 1.4 compliant, they should be able to work together.
In addition, something may be HDMI 1.4 compliant with audio return channel (ARC), which is saying it'll send video one way over the cable, and audio both ways.
Then there's a third thing in the HDMI 1.4 standard called Ethernet Channel, and that is basically saying that using that same single HDMI cable, if one of your components is networked (wifi or hardwired), that another component without wifi can piggy back off the network via the HDMI cable.
Of course, the components both have to support whatever feature. The Elite is 1.4 compliant, and also is ARC compliant. I'm not sure if it supports Ethernet Channel. I don't think it is but I didn't check on it since I know my receiver isn't so it wouldn't do me any good if the Elite is.
There are also different HDMI cables out there depending on whether it is "just" HDMI 1.4, or HDMI 1.4 with ARC, or HDMI 1.4 with ARC and Ethernet Channel.
