My Goal
To play my Steam games in 5.1 surround sound while enjoying 4k and HDR on my TV

My Setup
My PC has 2 GTX 980SC cards and I'm running Windows 10.
My TV is the Sony Bravia X930E and my AV "receiver" is a Sony STR-KS370,

The Issue
I haven't found a way to enjoy both 5.1 and 4K/HDR while playing Steam games in my living room.
My receiver is older and does not support 4K or HDR. My TV does support 4K/HDR, but I'm unable to get the 5.1 audio to pass thru to the receiver.

I know that surround pass thru works on my TV.
I currently have my PS4 Pro running direct into my TV for 4K, and with the TV outputting to the receiver, 5.1 is working in PS4 games.
The problem is when I run an HDMI cable to my TV from the PC, Windows 10 sees the device as the TV and I'm unable to select 5.1 as an audio output option.

If I run the HDMI cable to the receiver first, I AM able to select surround options in Win10 sound settings, but I'm unable to play games in 4K.
I can oversample by setting a higher resolution, but the TV will only display a 1080P signal.

Will probably wait until I buy the next gen consoles/build a new PC to get a new receiver, so was looking for a temporary solution to tide me over.

My Questions
is there a way to force Windows 10 to output surround even if it's not viewing the TV as a surround compatible device?

is it possible to run video and audio separate from a GTX 980, with one cable running to the TV and one running to the receiver?

or would I be able to purchase some kind of HDMI splitter to run the HDMI currently going into my TV into both TV and receiver?



I've been searching on this issue for a while now with no solution , so would really appreciate any tips or suggestions. :) Thanks!
