See my comments above. I've had my TV attached to my home theater for 7 years now....just have an optical cable from the tv to dolby surround receiver. If the input to the tv has dolby encoding, it goes out to reciever, regardless of the source (tuner, blu-ray, PC) . By your thinking I don't need the Dualsense controller, because I can run it from my remote(which I can't). Nor can the Dualsense actually control the TV. As far at the PC, all I need is a wirelsess keyboard and mouse, which I can't replace with the TV remote either. TV remote works regardless if I want to watch something other than the PC, which will go to sleep with no use of the keyboard or mouse.
I've yet to see any remote that replaces EVERYTHING,
