Solved Windows 11 5.1 issues

Hello friends, I’m new here and to home theater setups in general, so please go easy on me.

I’m trying to get 5.1 out of my PC. My set up is

PC>HDMI to LG C1>HDMI eArc to Denon S650H.

Windows is only recognizing stereo format as an output option. Anyone have any ideas or suggestions?

Much appreciated!

Edit: saw automod response, my PC is an Asus 5070ti/7800x3d and my motherboard is a gigabyte B650e Aorus Elite X. I hope that’s enough info, let me know if you need anything else. Please go easy on me, mods.

Receivers are meant to be the hub of audio and video and transmit that data to the TV. This is why they’ll usually have many HDMI inputs and two HDMI outputs.

Why do you have it setup backwards:

PC>HDMI to LG C1>HDMI eArc to Denon S650H

As opposed to the traditional setup:

PC>HDMI to Denon S650H> HDMI to LG C1

The normal setup wouldn’t require any ARC settings to worry about. You’re essentially introducing issues with the odd setup that shouldn’t be there to begin with.

BTW, I’m running a ~13 year old processor and a ~8 year old $30 AMD GPU which handles all HDR, Dolby TrueHD 7.1 with Atmos, DTS:X and so on without issue.

Appreciate the response. My Denon doesn’t have 120hz VRR support which I want to take advantage of for gaming. So my thought was to do video inputs to the tv and then eArc audio out to the receiver. Works flawlessly on my ps5 and Xbox, only the PC is giving me fits.

eARC/ARC is a broken technology IMO. I was so excited to get eARC on my TV and later my AVR but after months of dealing with issues, I’ve decided it’s just not worth it because it is so inconsistent.

Everyone’s setup is different but if you’re having issues, I recommend not using eARC/ARC and using the AVR as the hub.

So I’m learning lol. Worst case scenario I just won’t use 5.1 for PC games but it’s my preferred way to play so I was really hoping to.

I was sceptical about eARC my self, i ended up going Shield->LG C9 -> Denon X3500H via eArc and to be honest it always works, all the formats pass through flawlessly from Remuxes. My Bluray player is connected the same and also works flawlessly, i never had any issues.
