Connect Arc + LG Oled C3 + Apple TV 4K + Streaming box + 2-Era 100 for Surround Sound

My LG 3C TV has E-Arc (port 2). Some articles indicate that the Apple TV 4K should go into that port. Then I read that the Sonos Arc should be plugged in that port. Which do I plug in that E-Arc port? 
I need to start with that question as I’m having other issues.

Hi. I have another question with the above setup. Everything has been working well. But, tonight my Sonos app shows my Arc is on silence for 1 program. 
There is no sound on one show only in Prime going through on my Apple TV.  I can go to other programs on Apple or to my streaming box and they all have sound. 
So unplugged my Apple TV box and plugged it back in and now there’s sound. 
Can you think of a reason this happens? Actually this is the 2nd time it’s happened.

As a guess, the Apple TV or the TV set didn’t initialize the CEC ARC stream properly, and wasn’t sending correct data to the Sonos. It took a reboot to get that stream to initialize properly. Software is sometimes sensitive to power surges. You may benefit from putting all three devices on a surge protector device.

I will give that a try. 
Many thanks.
