Hi, i think this question or similar have been here before, but i dont wont to mess things up.

is there a simply way, to get DDL DTSI or Atmos through the HDMI from the GPU to the TV and per ARC to AVR ?

i know ARC cant pass uncompressed Surround Sound.

The LG C9 seem to have eARC, which does support uncompressed Surround Sound.
Check your receiver for eARC support.
If it doesn't have it, you will need APO Driver to add DDL on HDMI out.

Basically you will need to install APO Driver, select the below one (The one I have selected)

then open FX Configurator, select your HDMI endpoint then apply using Product Config Tool the proper software for enabling encoding.

Finally you go to the sound control panel and change the format support to HDMI (In your case it will be only "Dolby Digital")

For me the only way I can hear and see my computer is if I turn my amp on. For music and daily driving I set two channel audio in the audio control panel. For multichannel I go back in and set to my multichannel preference in the same control panel. That way the bass is where it should be, and same with all other sounds..

I am feeding my amp through HDMI via my GPU. I am only running 5.1.

Are you using ARC?
ARC has no support for uncompressed multichannel audio, and requires DDL for that.

Are you sure? I get True HD and DTS MA lit up on content that has it. Not for everything of course..

You might be using eARC, or you are using passthrough (PC>receiver>TV).
OP has a PC>TV>Receiver.

I have my pc hooked up to a denon x4200h which has no earc but using a 2nd hdmi out from my gpu, which has 3 hdmis and 1 dp , it sends fully compressed dolby atmos to my avr which the avr uncompresses, which is why you see atmos on the avr screen. I have a 7.2.2 with 2 inceiling speakers and 2 subs obviously , and it sounds freaking glorious, even gamesz which dont support atmos get the overhead sound because of dts neural x
