Realtek Modded Audio Driver for Windows 10/11 - Only for HDAUDIO

[pyuras]

@Ferather @Alan Finotty

Hi, guys.

Firstly, thanks for your continued work in this driver.

I'm having trouble with the lastest version of the driver (6.0.9137.1). I uninstalled the version I had previously (6.0.9129.1) using AAF uninstaller, rebooted the machine and then removed everything realtek and AAF related with Driver Store Explorer. Rebooted again then installed the new driver. It installs fine, but whenever I try to enable DTS I get this error:

Unticking "Audio enhancements" has no effect on the error. I went back to 6.0.9129.1 and everything works again (DDL and DTS Interactive 5.1). I didn't install any of the versions released in between. My motherboard is a Gigabyte Z390 Gaming M (ALC 892 codec). I connect the mobo to my Onkyo HT-R395 receiver via S/PDIF optical. Any ideas?

 

[Ferather]

Hmm, settings issue. And again ALC892. < I'm taking notes. For now can you do another cleanup and try the following guide and driver.
Dont use the other Driver app as it can break settings if the force feature is used, I ended up with restoring the partition.

DTS DCH Driver for Realtek HDA [DTS:X APO4 + DTS Interactive]

Thanks in advance. Note: You might need Alt 1, but first try main.

I've tested version 6.0.9132.1 and can confirm it has the same problem as 6.0.9137.1 on my hardware. Not only that, but it has no digital audio output at all (analog HP audio does work).

So, whatever changed between 6.0.9129.1 and the two newer versions broke functionality on ALC892.

EDIT: @Ferather I'll try the driver you suggested and report back.

 

[Ferather]

Taking notes. You might need to try 'DTS DCH 6.0.9137.1' first.

You can trigger 5.1 with VAC, and set its output (recording) to your speakers. You will need to disable windows audio service to apply some settings, see my screenshots above.
I have attached the full version of the app, fully unlocked, although it might not be the latest version, it works perfectly.

Edit: Dont forget to 'config' VAC to 5.1 or 7.1 when finished, the below screenshot is not VAC, as I removed it.

Edit 2:

You might be able to use my HDMI-DP setup files to trigger multichannel and perhaps stereo to your ALC892. You will need the 'RTK APO Tool', and my DTS-Settings files.
Open the tool, then change the device to your speakers at the top, change to 'MMDevice Registry', and on the right select 'EP Registry'.

This will open regedit at the device, right click the primary key, select rename, then copy it. Edit the .reg files with the info.

Now double click the registry file, then restart Windows.

I followed your steps and stopped before EDIT 2 because i don't use HDMI-DP speaker

with VAC and the DTSX Ultra shows yellow "external speaker" but i cannot hear any sound effect

if i stop the DTSXAPO4 service, the sound effect makes no different at all

if i change all my config to Stereo (vac and native realtek sound settings), the DTSX Ultra show "please connect to speaker " again

so it doesn't work for me....

 

[Ferather]

Programming around chip code is very difficult, although I am not 100% sure if its the chip bugs or other factors, always seems to be 892.

 

[pyuras]

@Ferather

I installed your DTS DCH 6.0.9137.1 with the M (main) option. Everything is working fine (I didn't have to untick "audio enhancements"), although I don't have the Realtek Audio Console installed (DTS:X Ultra and DTS Headphone:X v1 are installed).

EDIT: Found the UWP package for the Realtek Audio Console in the APPS directory. My bad.

 

[Ferather]

Then you're lucky with your chip revision.

 

[pyuras]

Then your lucky with your chip revision.

Should I try DTS DCH 6.0.9137.2 then? How do I safely uninstall your drivers?

EDIT: Is it possible to enable a dedicated Headphones output?

 

[Ferather]

That's up to you, to remove it simply follow the guide and aim for all 'DTS' drivers and extensions.
Yes, see here, you enable headphone via a separate stream, then restart.

Windows Update downloaded some "DTS software" and now the audio doesn't work.

 

[Ferather]

Do you mean the Windows store? If so disable store updates and uninstall the app, then re-install the provided one.
Else I am not quite sure what you mean by DTS software, the components don't have drivers.

Windows Update downloaded some "DTS software" and now the audio doesn't work.

check Update History in the Update & Security settings window and see what kind of DTS software was installed by WU (DTS APO3x? or DTS APO4x?)

NEW DCH DRIVERS RELEASED IN GITHUB
DCH DRIVER VERSION UPDATED TO 6.0.9132.1
MORE DETAILS IN GITHUB

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.

WARNING: There is also an update for Nahimic on the Microsoft Store to version 1.5.4.0, but it is very likely that once installed, your enhancement will stop working.

Those who want only Realtek material, just choose the panel option (HDA or UAD), select your decoder and deselect the rest.
GO TO 1st PAGE

ENJOY!!!

regarding recent Nahimic UWP app versions from MS store - v1.5.4.0 is no longer offered from MS store.
MS store recently offers either 1.5.7.0 or newly released 1.6.5.0 of Nahimic UWP app

 

[Ferather]

I'm hoping that's what he means. I can now confirm the ALC892 that refused to run the service is now working as intended with my DTS DCH driver.

Which service?

 

[Ferather]

APO4, It would run APO3 but not 4 or 1.

 

[AAF Optimus]

APO4, It would run APO3 but not 4 or 1.

I asked her why my PC's motherboard is a Gigabyte GA-880GM-UD2H and it also has an ALC-892

 

[Ferather]

Told you that chip is strange.... I can only think of the driver store app issue, but I don't how the two are related.

Edit: The two friends I have with 892, in working state, are using Windows 20H2.

@Ferather No. After I installed your driver, Windows update downloaded 3 "DTS - SoftwareComponent" the first time I checked for updates (see screenshot below).

check Update History in the Update & Security settings window and see what kind of DTS software was installed by WU (DTS APO3x? or DTS APO4x?)

@erpguy53 @Alan Finotty

After that, the driver stopped working and no sounds could be played. I uninstalled everything and am back to AAF version 6.0.9129.1 for the time being as it's the last one that works correctly for me.

I'm also on Windows 20H2.

 

[Ferather]

I will check this tomorrow. Thankyou for the feedback. Edit: Issue fixed.

@P_G19

E-APO doesn't support composite, and it can only make 1 composite with another effect. If I enter for example DTS-SFX into APOTool, then add E-APO it will use existing apo (DTS-SFX).
Due to the composite limitation with E-APO, you can only have 1 other active APO (DTS, Dobly, Nahimic, etc) at a time with it

Ok
Thanks for the info.

Love my Z906 even more when I can plug headphones into the head unit, and get 5.1-7.1 over a standard pair of headphones, via Toslink (optical) to unit.
Even DTS and Dolby encoded content plays all the channels over headphones via Z906, similar to this wireless, but not wireless.

Checkout this bitrate and DTS-HD passthrough, not normal DTS: https://streamable.com/302a0c < Turn up speakers.
My guess is the Z906 actually receives the full rate, but probably only plays the core.



SPDIF - Toslink (optical). Av it Dolby!!

In that middle window, under ”Mixer settings” what are the “Expand stereo to centre/surround” options? They were on by default for me, even for non-headphone use. Should they be off always? (I didn’t notice a difference when toggling).

 

[Ferather]

Its stereo expand rather than surround, that's up to you. It will only take effect if you set speakers to say 5.1 and stereo audio is played. Exactly like Neo PC.

Ok, so it probably wasn’t working because I’d set the speakers to ‘match source’ or something like that within PotPlayer settings.

Which is good because I don’t want stereo playing across more than 2 speakers.

Just thought it was strange that those were ticked by default...Maybe I’m better off unticking them.
