I was at my parents place and I found an old Onkyo TX-SR800 receiver they are no longer using just sitting in the basement. It was a great receiver back in the day and I took it home to see if it still works with modern equipment.
The speaker connections are fine and there no issues there. What I'm struggling with now is getting it to connect to a modern TV and other components that use HDMI with no analog. Instead of purchasing a bunch of converters to plug components into the receiver, would it work if I were to plug in all the HDMI components (Roku, cable box, PS4 etc) into the TV and use a digital optical out from the TV into the receiver? That seems to be an easier route but I'm not sure if that would work.
