I have a Samsung Q60 series TV connected to a Yamaha Receiver which feeds 5 speakers and a woofer. They are connected by two HDMI cables which originate at the receiver HDMI out and at an HDMI in (I believe). I would like to be able to transmit sound to the receiver from whatever is onscreen, whether that's a video game, Netflix movie, or Hulu. I have read that I need at least a HDMI 1.4 cable and to enable the HDMI-CEC protocol in settings. How can I tell whether the cable in 1.4 and is there anything else to consider here?
