Hello! I just got a Samsung smart TV and want to output audio over HDMI to my older Yamaha RX-V1800 receiver. It doesn’t support 4K passthrough so I need a direct HDMI passthrough to the receiver. Is there any way I can use the HDMI ARC and direct audio directly to my receiver? Optical output only supports 5.1 and I have a 7.1 setup so I want to use HDMI which supports 7.1. Thanks!
