Sorry nothing I can do about it, I have tried now for days. I guess you will have to wait for another driver pack.
The only thing I could try, is if you sent me a link to working drivers, and I add it to that.
This being said this will cost me time and effort, just so you know.
====
Just diagnosed a friend with ALC892 with exact same problem, now its working. I will write a guide shortly.
The problem was other drivers, previously installed, and apps used to remove drivers.
====
DTS DCH 6.0.9116.1 is a driver fully written by myself (except the base files that come Realtek), with no other direct influence on any code or time spent by third party sources.
----
Main directory:
https://www.mediafire.com/folder/9yrokjhyh2slx/DTS_DCH_Drivers (note, the Ferather preset is different to the one installed).
Alternative link:
DTS DCH 6.0.9116.1.7z - Anonymous Files (no tracking, logs, and so on,
https://anonymousfiles.io/).

How to cleanly install
DTS DCH 6.0.9116.1 (don't skip steps), turn off your internet - unplug the cable or turn off wifi.
DO NOT use third party software to skip steps.
If you have used my drivers previously, you will need to delete any files in 'C:\Windows\System32\DTS' after uninstalling the device.
This issue has been fixed in the current release, and you will not need to take any additional steps in the future.
----
First uninstall all
Realtek,
AAF,
DTS or
other installations from 'Apps & features'. Then restart your computer (it will probably ask you to restart).
Then in 'Device Manager', check for '
Microsoft Audio Device', If it still says '
Realtek' or '
AAF DCH Optimus Sound', you might have an issue.
Right click the device and select 'Uninstall', then tick 'delete driver', and restart your computer, repeat until the above.
*
* If you
don't see '
Microsoft Audio Device', you need to repeat the process until you
do.
----
Now open 'Command Prompt' as
admin (note, you can select screen text, and press
ctrl+c to copy, and
right mouse to paste):
Type the following command:
pnputil -e , this will display all installed drivers, look through the
vendor,
device and
signer list, copy the
oemX.inf name.
Now type the following command:
pnputil -d oemX.inf , this will delete the driver, however it must not be in use (uninstalled).
If a driver fails to remove, uninstall the 'Microsoft Audio Device', do not restart, and try again (it will now).
Make sure to remove
everything related to your Realtek, including past installs.
Now run a registry cleaner (
CCleaner) 2-3 times, and restart.
----
In some cases, active third party audio software can cause bugs with registry entries, example Viper, I have only tested Equaliser APO (E-APO).
----
Double click install, wait for Windows to tell you to restart, wait 5-10 seconds then restart. Read the proved Readme.txt, now configure your sound setup.
If you are using the APO3 entry (ModeFX), please remove it when not needed, in order to use Ultra and other effects.
----
Inside the folder 'WIN10\APPS\UWP_Store\' you will find two .inf files, right click and install these to get Headphones:X v1 (APO3) and DTS:X Ultra (APO4).
DTS Headphones:X (v1) -
https://www.microsoft.com/en-us/p/dts-headphone-x-v1/9pfndb3vh40p?activetab=pivot:overviewtab
DTS:X Ultra -
https://www.microsoft.com/en-us/p/dts-x-ultra/9n0h1m8j1308?activetab=pivot:overviewtab
====
Fully functioning 6 channel balance for SPDIF, digital optical in this case.
====
When in multichannel mode (4, 5.1, 7.1), Ultra will use a multichannel preset, for 4+ speaker and effects.
If you require additional effects either use the Realtek Audio Console, or E-APO (ignore digital format).
If you need the old DTS Connect system, follow the Readme.txt for the property key.
I recycled the above screenshot, I'm lazy at times.
====
How do I get Ultra on my HDMI-DisplayPort GPU?
You have the Ultra mod working on your Realtek device? Open the provided tool: RTK APO Tool, at the top select the HDMI device.
Input the following, and press only write,
NOT write default (will make it permanent), you can reset if needed.
Stream: {07531B73-E4CA-4B94-9D0E-D3C9A7825FE5}
Mode: {FCDD3010-BB3F-4B24-8074-A18FC7D558F7}
Endpoint: {599C2638-CC15-4FFE-B16A-9246260D2DF7}
Now restart the 'Windows Audio' service, or restart your computer.
====
You can also try and add-unlock features (perhaps your device supports DTS UltraPC II) use the provided 'RTK Device Tool'.
If you make a mistake copy 'RTKHDAUD.dat' from the drivers to C:\Windows\System32\drivers.
Don't press the flashing text, it will delete the config file.
In some cases you may need additional files.
====
Make you store E-APO's key in case you need to change it at a later date.
Stream Effect Clsid: {EACD2258-FCAC-4FF4-B36D-419E924A6D79}
If you want the DTS APO1, you will need to remove the E-APO line.
Note: DTS APO1 doesn't support WASAPI shared mode.
====
Below is an additional tool (cleaned), which contains 'Effect CLSID's.txt'.
