If folks want the best picture from their TV or 4K Player PS4 Pro or any other main Video Harder its always best to have those plugged into the Once Connect Box or whatever 4K Brand you may have. Audio receivers seems not to handle video well and Again since there are so many some might work better than others. But usally the video and PQ takes a hit going through them the only time I would suggest using a Audio Receiver would be just for extra HDMI Ports is all. Folks should use the main HDMI Ports on the One Connect for their main devices and just use the Audio Receiver that just that to handle the audio. So the easiest and less headaches is just to run a Digital Audio to the One Connect back to the Audio receiver for sound. If folks want their other devices to have surround sound to work they might have to use digital audio cables hooked to those devices back to their audio receivers. At some point Samsung probably should have a list of Audio Receivers that have been tested for that specific feature to work. But it will take both parties working together to make it a smoother process.
I will agree HDMI ARC is typically hit or miss, considering you have multiple devices that all need to be working correct for it all to work. Anytime you have ARC issues, power everything down and back on. If that doesn't work - power everything down and unplug, then power back on. Seriously, sometimes things get messed up and fully killing the power to them is the only way to resolve the issue.
As for AVRs and running HDMI through them, I will have to say that modern 4K AVRs don't degrade video quality at all. They will passthrough 4K HDR just fine. Another thing to consider is Dolby Digital Plus. If you run devices into the One Connect box first, and use optical out - it typically won't send DD+ because of bandwidth issues. You will only get DD.
For me and the KS9000, the other thing I noticed was a lipsync issue with devices connected to the One Connect box and then out to the AVR via optical. This didn't affect the built in apps, but I definitely had an issue where there was an audio delay to the AVR. Tried all the delay settings I could, but I couldn't solve it.
For me, I have everything running into my AVR via HDMI and then out to the One Connect box. Only exception is my PS4 Pro. I have that plugged in directly to the One Connect so the TV can auto switch to that input which is set for game mode. Because of the optical delays, I'm using optical out directly from my PS4 Pro to the AVR.
I played with ARC, but I hated it. Don't like that you have to have Anynet on in the settings. I have a Harmony remote that controls everything. With the Anynet HDMI control, the TV wanted to control my other devices.
