So I decided to go with an optical cable. I figure the physical work required to rout it is worth countless hours of frustration dealing with ARC. I tested it out and it works great.
Thank you all for your help.
Put simply: Less wires.
The setup is run behind the wall. I can run an optical line but as a temporary solution, it would be a single wire running down a clean wall. And as a permanent solution, I would need to resnake it through the wall.
Like I said in my original post, I'm not an AV expert...
I've tried every combination of settings possible that it allows for.
I also just remembered some issues I've had with this ARC connection in the past.
About a year ago, I had a Nintendo Wii connected directly to the TV using an HDMI converter. The sound would work *sometimes.* Other times it...
I know that ARC works as it is set up right now because powering the TV on and off will automatically toggle the receiver as well. Plus, the receiver has a small LED signifying that it has an HDMI ARC connection. This LED turns off if the ports change or ARC gets disabled.

I've been racking my brain around this for way longer than I care to admit and it's really frustrating me. I am no expert in this field, but I'm also not completely illiterate.
First, what I'm using:
TV: LG 65UH6030-UH
Receiver: Yamaha YHT-5920UBL
So, I have a setup with various devices...
