Uninstall and switch to "both decoders", this should fix your problem. I dont see the point of the DDL only option, and as mentioned it uses a different APO (seems to have issues).

@Romulus2K4, leongx

Nearly all of the apps are UWP apps, and uninstall very easily, Nahimic requires an additional driver, this gets removed in uninstall, the THX panel is an installed .exe, using an installer.
I also did an install at some point to test out the THX paneI, I used CCleaner to uninstall it, you can also remove any start-up entries that did not remove (which they did).

Try and follow the path of the start-up entry and see if you can find where it's located on your disk drive and delete the folder, then run registry cleaner.

I did not, but for good measure, unplug your network cable, uninstall AFF, restart, then in "Device Manager", right click "Microsoft Audio Device", uninstall and tick "Delete Driver".
If you don't get the "Delete Driver" option, don't bother uninstalling and cancel, if you do, repeat until you don't, then install AFF, restart, plug back in network.

--

If you want global (all apps) stereo to 5.1-7.1, follow the guide in my signature at the bottom of this post. Post 3 has the latest config files.
Post 4 is optional. E-APO will upmix stereo 2 channel into 5.1 and 7.1, it will also connect to DTS or DDL on digital.

Adjust the Bass-LFE channel to suit in the "upmixer", DTS-DDL and my Z906 = mega extreme bass.

@OneMoar

That's pretty common with Windows, that's why registry cleaners exist. Even official drivers and software can leave behind reg keys and entries.
Alan doesn't control registry entries made by software, that's down to the developer of the software.

You can install Sonic Studio from the store and get reg entries.

OR the installer should do what installers do keep a record of everything it does and undo it when the time to uninstall it comes else why even have a installer

That's possible, currently its more of compilation of 3rd party software (software suit), I do bare minimum personally (just drivers + decoders).

Idea for @Alan Finotty: Base pack (just drivers + decoders), and Software pack (other apps and components).
It would also be good if the software pack can be modified rather than re-installed.

Coming from an Asus DGX with the Uni Xonar drivers installed. I’d like to move away from using the sound card and use the onboard audio on my X570 Aorus Master, but I use the Dolby Headphone virtualization in quite a few games. Do these modded drivers allow me to retain that ability? Or am I better off just using Dolby Atmos for Headphones instead?

EDIT: I use headphones connected via 3.5mm connector for what it's worth.

As far as I know the Dolby Atmos app that comes with the AAF driver supports headphones. It should look like this (cant remember, not using it).

AFAIK \apo keys are read initially from the driver files, but can be changed, if the device is re-installed or reset, the apo keys (or lack of) return.

Right, and I was already able to use Dolby Atmos for Headphones before. But is it the same as the Dolby Headphone virtualization that I've been using on my sound card? Basically my understanding is that Dolby Headphone virtualization takes the 5.1 source audio and maps it to stereo headphones, giving the effect of surround sound. By using Dolby Atmos for Headphones would I be experiencing the same effect and at the same quality? I just can't find enough info about this stuff.

Yes that sounds correct from what I read also, I cannot say for sure because I don't use stereo, headphones or Dolby Atmos, sorry.

----

Headphone and smartphone implementations

Dolby Atmos also has headphone implementations for PCs, the Xbox One, and mobile phones. They work by using audio processing algorithms to convert the Atmos object metadata into a binaural 360° output using the usual two headphone speakers. This technique is an improvement on the previous Dolby Headphone technology, allowing for infinite channels of sound to be processed into a virtual surround experience.

Hello, thank you so much for your effort. I have one problem. Soundblaster is unable to detect my audio device correctly when using SPDIF. It only detects when I insert headphones in the front case aux. I've tried to run the KGAConfig exe but that didn't solve my problem. Any help?

I have a question: What's the difference between the DCH-UAD Version and the Standard Version?
DCH-UAD is geared towards Windows 10 and Standard is geared to previous systems starting with Windows 7.

Thanks! Another question. I have Equalizer APO installed (see pic). Do I need to uninstall it before installing the drivers?

Gentlemen! Question - It does not work for me - most likely the question is in your equipment ... I have 2010 - Yes! Everything works. You must first remove the traces of the previous sound drivers, and then correctly - SUPPLY ALL BY STEP - and there will be no problems.
Here are my screenshots, and here is the thread in Russian,
where I explain how to put it correctly (turn on the translator - and that's it!). There are also codes that need to be entered.
Alan! - write them on the main page!
P.S. - I do not argue, maybe something does not work with digital output or optics, this is different. But the mod itself WORKS EXCELLENT AND THE SOUND IS AWESOME !!!!
P.P.S - In the HDA version - add an equalizer - easy - you need to enter the code (reboot every time after introduction)
P.P.P.S- After the introduction of this code: Chip 889 becomes 890 .... and this is the equalizer ..I have Rampage III Extreme
I've been putting on Alan's fashions since May 2020 ... - so I know what I'm writing about


For whom it is difficult to translate:
Removal / installation looks like this: Net is disabled.
1.Revo unistaler - remove the standard Realtek driver .... in short, everything related to sound (create a restore point for everyone) Revo will also create it - we clean everything, delete it, WITHOUT RESTARTING, everything with sound ...
2. driver store explorer (on behalf of the administrator) - delete realtek, dolby, dts, Alan Finnoti (if any) - forcibly check the box on the right in the corner.
3. Grind CCleaner (Registry) - 2-3 times until completely delete - do not save - not found.
4. Reboot (preferably without the signature of the drivers - F7 - just for everyone)
5. Windows will install
HDA compatible device (There are sound improvements in properties here).
6. Program Data - delete folders (if any) A-Volute, Dts, Dolby. CCleaner - registry - do not save - delete (2-3 times). (I control, in the regedit registry, I look at the software - so that there is no dts, Dolby, realtek - if there is, I delete it, who does not need it, skip
7. Installing AAF (the choice is yours) Uad - simplified - nothing needs to be done - mood for yourself .. Hda - while I see more variations ..))) Good luck! Then post to the techpowerup forum ...
8. Include Net.

Oh you got APO4 working, very nice. Hope my files helped.
The version I introduced in the driver is more recent than the one you indicated.
