I currently have a tcl Roku tv and a Yamaha RXV471 I got from a thrift store and factory reset/fixed some ports. I am using optical because Netflix and other apps did not utilize the ARC connection, nor did CEC detect the receiver. Netflix I believe does do surround sound, but apps like science go and tubi don’t. I don’t have access to it the settings in the * menu because I disabled the TVs speakers.
edit: I have DD enabled instead of DD+ in settings
