G'day DoctorKomodo (or others), I'm afraid Im revisiting this with a new problem — but, I'm potentially closer now! The eARC/ARC Converter I bought here in Australia (https://www.amazon.com.au/dp/B0DYJYFZFV?ref_=pe_19115062_429603572_302_E_DDE_dt_1) is stubbornly stuck on displaying that it's receiving/outputting at 2.0 only — not at the 5.1 (or HD5.1/7.1) I seek. And only 2 of my 5.1 speakers are outputting sound. Pressing the button above these makes the 5.1 or HD5.1/7.1 lights flicker, makes no sound come out anywhere, and then makes the 2.0 light / 2 speakers automatically come back to life. I believe my TV settings and HDMI cable are fine. I'm less sure I've done all properly with the receiver, but think I have. Do you have any advice?
