ATTENTION: You will need to uninstall the currently installed version before continuing with this installation. A condition has been imposed for this due to problems reported by some users.

ATTENTION: Before installing this modified driver, be sure to remove any and all residues from previous Realtek audio drivers or even if there are residues from previous versions of my mods, if they persist. For this you will need the DriverStoreExplorer (by @lostindark). Remove any drivers whose vendor is "Realtek", "A-Volute", "Dolby", "DTS", "Creative", "AAF Optimus", etc in the Sound, Video and Game Controllers, Extensions, Software Components and Audio Processing Objects categories.

Those who want only Realtek material, just choose the panel option (HDA or UAD) and deselect the rest.

You don't. The encoder endpoints don't do anything but encode. They're just a link to the working .dll in question that handles encoding the active audio streams. Dolby Digital Live and DTS Interactive each are pretty easy to make run without any actual audio processor programs.

But which Apps are working with this DLL?

The operating system is. Not any apps. When you tell Windows that your current endpoint's that all those {d04e05a6-594b-4fb6-a80d-01af5eed7d1d},XX keys are specific values that align with DTS processing or Dolby processing of whatever class? That's the only tether needed. There's nothing more needed as an input beyond that properly-configured key telling the system that that DLL is doing the work. No 'app' or program or process is doing it necessarily beyond Windows's audiodg.exe.

Hi Alan.. Thank you very much for your driver update. I'm just confused about your last driver installation process, why is there no more panel options for HDA or UAD?
By the way I've tried 3 times the various feature options available on installation. The goal is to install a Realtek HDA panel, but as a result I'm always presented with a UAD panel installed, which in fact can't open or operate (always force close) on my device's OS. (Windows 10 21H2 latest version).
I hope there is enlightenment from you. Once again, thank you so much.

Hey, I installed this driver on my MSI GL62M 7RDX (which uses Realtek audio drivers) and when I play any sound, I hear static at the end of it. Also, when I use the voice changer in Sound Blaster Connect 2, after I finish saying something there is massive feedback (like a big ringing sound from a mic). Final issue, if I plug the laptop up to both an HDMI TV and my headphones, the sound refuses to go through the headphones and only goes through the computer or the HDMI TV. Do these drivers not work for me or am I doing something wrong?

Edit: So after a bit of deduction the headphones work when I startup the computer but when I open Sound Blaster Connect 2 it refuses to work

Hi
Recent KB5016616 broke my audio mods I've been using long time. Finally fixed but figured I should learn how to get current drivers working before Win10 "feature" update forces me onto new driver.

I've been using RT HDA legacy driver 8899_FF00 + APO driver / fx-configuration. Patch for DDL 5.1. Also use Dolby home theater 4. I've played with other FX but always run into conflicts and issues. So I've just stuck with this config. The DDL 5.1 + HT4 makes my Yamaha receiver sound like it should.

Any new HDA driver version I've tried newer than 8899 the APO driver / fx-configurator DDL 5.1 patch (RLTKAPO64.dll) will not work.

I just tried Optimus HD AUDIO DRIVER VERSION 6.0.9384.1. Installed everything but sonic III.

DDL 5.1 works. But my trusty home theater 4 apparently doesn't want to work with DCH drivers? Gives driver error and won't open.

What is the modern equivalent home theater 4 Dolby app that would function with the Optimus HD AUDIO DRIVER VERSION 6.0.9384.1
(The Atmos in Optimus package doesn't want to run and then upon reinstall its now not present? Trying again...)

Edit:
Asus Maximus X Hero WIFI
CODEC S1220
SPDIF

Edit 2:
Uninstalling UWP atmos for gaming the Optimus installer would never reinstall it. I obtained it elsewhere. DolbyLaboratories.DolbyAtmosforGaming_3.30201.210.0_x64
Get black screen - not compatible with device. On last install I only installed patched driver + atmos thinking maybe other apps conflicting.
I guess its back to HDA 8899 drver + HT4 for now.

I uninstalled my old AAF drivers and wiped everything with DriverStoreExplorer as instructed. I installed the newest drivers and everything seemed to go OK but I have no volume control on my laptop. Even with the volume turned all the way down to zero and muted in Windows the actual volume is still very high.

Thanks Alan for the new update. Is in this new release option for realtek HDA panel menu already available? Maybe tomorrow morning I'll give it a try.

[Update]
It turns out that in the latest driver update release, I still can't find the realtek HDA panel option. Only automatically redirected to the UAD panel. But the UAD panel in this latest release can already be run. Even without the equalizer menu. Only the volume menu is available.

Will revert to the version where HDA panels are available. While waiting for updates/fixes.

Hi alan ty for the new drivers, i tried to install Sound blaster x-fi mb5 but it did not install

EDIT:
Hi alan mi again the REPACK SOUND BLASTER X-FI MB5 kaspersky detects something and deletes the file, I think that's why it doesn't install with the full installer AAF

EDIT2 : Sound Blaster Connect2 is broken in my ALC887, no work

Hello Alan, is there any solution for my problem mentioned above?

@TheRockZBK Use the original Sound Blaster X-Fi MB5 installer to see if it works. Link available on the 1st page of this topic (ORIGINAL INSTALLER)
