A:Answer To use your receiver as a surround sound device and your associated speakers you need to enable ARC. Depending on your HDMI cable you may or may not need to attach an optical cable. I've seen where an HDMI cable should provide audio, but I needed to attach an optical audio cable and mine works perfect. You'll also need to determine what audio setting to use. My normal all comes in on #1, but the Netflix with ARC and TV direct antenna comes into the receiver on audio 4. Hope this wasn't confusing.
