I am looking for direction on disabling "system audio control" feature. I have an AVR connected to HDMI 4 EaRC input, and every time I power on TV it triggers the AVR to power up. I dont want this. I found that there should be an option to disable system audio control when enabling EaRC feature in menu. I do not have that option appearing. Only other item I have connected is a Zvox Soundbar via optical out. How can I enable/disable the system audio control?
Having the same issue with my 8 Series and Sony AVR. Looking for a solution too.
