The Onkyo receiver has an ARC HDMI output. I HDMI'd it to the Samsung "One Connect mini" input labeled HDMI ARC. I am not sure if you are familiar with the Samsung One Connect mini hub. It is a device that is external to TV that I guess is utilized in switching all HDMI sources and allows the use of just one convenient HDMI connection to the back of TV. Is there any specific way I need to connect this? Samsung support was of no help when I attempted a live chat to troubleshoot this issue. There must be something that needs to be disabled/enabled for this to work properly.
