Is there a firmware update available?

Is your soundbar set to Dolby Digital mode?

Did you install Dolby Home Theater V4?

I just checked and my soundbar and tv are both the latest versions.

My soundbar doesn't have a dolby digital mode but I do have on the surround sound and 5.1 works with my apple tv just fine.

I did install Dolby Home Theater V4 and when I did this it gave me the option to switch to dolby digital in the advanced tab under all of the other quality settings (like 16 bit, 44100Hz and a few others).

u need a modified driver to unlock dolby digital over nvidia hdmi ( AlanFinotty driver mod)
then u go to audio settings > channel settings > choose DOLBY
now all the system will be encoded to dolby audio in realtime

BUT...maybe not make a 5.1ch output...just a stereo for the system itself

I installed that driver mod and whenever I try to open the sounds blaster x-fi app, it says the audio device is not supported.

So thanks to fatguy posting earlier about a different forum post, as that allowed me to install everything without a modded audio driver. He linked to a forum but it landed on a random page, so I had to search around the time he posted here, April 2020, and found the creator of the APO utility saying to install the FX Configurator and Dolby DS1 7.6.5.1 (as of this posting). I didn't need to install anything mentioning PCEE. Just set the device you want with the FX Configurator the way that fatguy showed with that imgur link (https://imgur.com/AK0MMko) and then run the Dolby Install from his zipped file. It took me way too long to get everything together that he did, so save yourself 30-60 min and download that from page 1 on this thread and get this up and running right away.

TL;DR:

Download the zip file from Fatguy
Unzip and install APO driver, selecting "FX Configurator" and "Dolby DS1 7.6.5.1"
Use FX Configurator to set the device you want to using Dolby Home Theater v4 (HDMI/SPDIF), illustrated here: https://imgur.com/AK0MMko
Install DolbyHomeTheater.msi from Fatguy's zip file
Go to your device in sound window (looks like old control panel, not modern settings page), click properties, and if successful, you should have a "Dolby" tab and in Advanced > Default Format, a "Dolby Digital" format.

Test surround sound via the 5.1 surround sound file Fatguy listed earlier via Windows Photos app (direct link here: https://www2.iis.fraunhofer.de/AAC/ChID-BLITS-EBU.mp4)

Thx you and mr., fatguy. Now I got 5.1 sound with my lg c2. Connection -> RX7900 xtx HDMI to LG C2 HDMI -> LG C2 Optical spdif pass through to 5.1 speakers with DD.
