DisplayPort for audio only?

So I'm trying to get 5.1 sound from my PC to my my sound bar. However, I keep having a bunch of issues:
1. Using my TV as a pass through works except no surround sound as the computer doesn't "see" the sound bar.
2. Using the optical out on the motherboard also doesn't provide 5.1.
3. Using an HDMI port for the TV and a DisplayPort to HDMI via my GPU to the sound bar gives 5.1 but the PC thinks the sound bar is a monitor and restricts the TV to 1080/60hz.
I've searched for a bit and while I've seen people with the same problem, no solution is ever offered.

Do you have a sound card, or is it on board on your motherboard?
Has ARC but not eARC. Has a "digital" input that might be 3.5". Does have a USB though I think I remember it saying it was only to play music off of.
TV is TCL R635 and has both ARCs.
PC is onboard audio. It's based on the RealTek AC1220 chip.

Have you checked that your HDMI cables are 2.1? Also, if you're not using the TV as your monitor, your PC can probably do sound out to USB and video through hdmi to your monitor. If USB is sound only, but you only want sound, that seems right?
ARC is audio return channel, is an HDMI 2?/2.1 spec that does audio only through hdmi, but then you would need a tv/monitor that does ARC output along with 2.1 Hdmi cables. If your TV does ARC output, it seems like it would work fine, if your cables are the right format
Edit 3: I don't know much about displayport stuff
I don't have a USB cord so I can't check that.
If the TV would just pass through the signal it would be fine.
All the HDMI is 2.0 outside maybe the sound bar.

With the current setup, your TV would have to be your monitor to do the pass through, I believe.
A quick search says ARC was a part of the HDMI 1.4 standard, so if your cables are 2.x they should work.
Also, the optical out should just work, as far as I know. Optical is capable of 5.1, for sure. Not sure what that option isn't working for you
Might be worth it to get a internal or external sound card for the PC?
No option in Windows 10 to change to 5.1.

From what I'm reading, optical only has enough bandwidth for compressed 5.1 audio.
What's weird is the PC can do 5.1, the PS4 can do 5.1 (through the TV), the TV can do 5.1 through the Roku apps.
Yet passing through PC to TV to sound bar doesn't allow 5.1. The option is there but greyed out.
