I took a different route with my LG TV and HD621. I bought a de-embedded that connects to the EARC channel on my LG TV and sucks HDMI audio from the TV and onto my HD621.
All of my UHD video devices connect to the TV. The HD devices to my HD631z
The de-embedded was around £45 from Amazon So if I understand that right.. you feed the HD621 with audio only on HDMI? So if you’re watching UHD via HDMI 1 (for example) HDMI 2 EARC feeds the audio into the HD621->pre Regards David
