There are Audio Extractors that claim to send the lossless audio to the receiver while sending the 4K @60hz HDR video to the TV. The one pictured above claims to do so and includes a selector for the audio of choice. What I think
@Maddtix wants is a splitter/extractor combo that all of their devices can be plugged into and have one HDMI video output to the TV and one HDMI audio output to the processor. This would eliminate the need to change input sources on the TV and processor and device selection would be done on the splitter/extractor. But, can't say I'ver seen anything like it. Again, if 4K@120hz is the goal, forget about it. Connect the gaming consoles directly to the TV and use ARC or optical to get audio to the processor. If you only need 4k@60hz HDR and want lossless audio, try connecting an Audio Extractor to each console. Results will vary of course based on the settings of all of the components involved and the spec of the HDMI cables in use.
