Tonight, I will finish running the analog audio cable to the kitchen and get the IR repeaters set up so I can get that ugly little pyramid off the island. If I have time, I will also pull out the rack again, connect the linker directly to the Roku and the TV, so I can sniff EDID settings while playing back HDR content without the receiver in the signal path. That should give me the most accurate metadata for my HDMI inputs and allow me to finalize the settings on the Linker.
