Hello, hoping someone can help as I'm totally out of my depth. I have an RCA model RLED4627 A-B. It has no optical connection. It has 3 HDMI outlets but none say ARC. I bought one of these HDMI converters https://www.amazon.ca/gp/product/B06VVTQY8D/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 and one of these converters https://www.amazon.ca/gp/product/B003O509PY/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1. I hoped one would work. So far I've got sound coming out only for TV using the HDMI converter but there is no sound for any of the other HDMI outlets that connect the Apple TV or the DVD player. And I can't bring up the Yamaha soundbase set-up screen. Could anyone walk me through what I should be doing?
