I'm really enjoying the new preset from @ador250 + my multichannel edits, enough bass to turn it down with a LFE (5.1), sounds amazing with the new drivers.
Here is a source for analogue 7.1 (PCM), if you play it over SPDIF, you will notice side channels is played as virtual sides (front-rear combo).

ALC887 rev. 1003, hmm try ALT1 driver rather than main.
tried with latest version for ALC 887, but same problem, I hearing music output through microphone.
Somehow problem is with this realtek setting with your driver, looks like ignoring this setting:

Now installed Alan's driver without SPDIF DDL/DTS decoding (because cant make it work) where is no problem with microphone with AEC on.

Using the provided RTK Device Tool, try the following, for me beam forming works best.

enable DrvCtrl 14
check 5-MicEffectStereoOutputForAECandNS

enable DrvCtrl 43
check 25-AecRefUseLoopback
check 24-ForceRtkMicEftV2

enable DRVCtrl 38
check 31-AecRefSupportSrc

@Kabal81, I might able to do something now I understand APO3 and APO4 more, I have been asked by friends. Sometimes if you stack APOs you get problems.....
This driver uses Sound Unbound and the Headphones:X (v1, v2) apps for spatial, it also has object processing, and works with Atmos encoded audio.

----

So I addressed APO3 fully, and re-mastered its preset, and set it up to not screw up other APO's, you can now use APO3 for stereo, or ignore it.
I managed to get the same latency stereo had without APO MFX, now with MFX. You will need to select Surround or 3D mode.

----

DTS DCH 6.0.9137.4 (Signed) - See post 1 for the downloads and guide. Various APO fixes and changes, moved apps to one package.

@Bryan Ü, you want ALT1 (HDXRT2.inf), I moved them around, but have now labelled them in the basic installer.

----

If you want to edit or tweak the preset's, or find better settings let me know:
Drag and drop any files to the right folder, then install (or edit first).

====

Forgot to mention, DTS Interactive (analogue > digital), has been upgraded into essentially Interactive:X, with DTS 6 channel endpoint effects and 6 channel object processing.
The sound quality for me is better *, however I notice a difference with high frequencies, nothing an EQ cant boost. Specs: 48 Khz, 24 bit, 6 channel.

* Versus analogue 6 channels, and the same speaker system, high grade cables in both cases.

Thanks for your answer. I will wait then and watch your updates. For now I'm happy and your driver does its job pretty well.
When you start your work with spatial sound enhancements like Atmos and stuff, I can do some testing stuff :)
You're doing an amazing job here!

Thanks for the feedback. I'm taking notes for the next Realtek release, and will add any changes then, unless urgent.
I am still investigating multichannel for SPDIF with some chips, such as 887 and 892.

Current release, with maximum performance, and high quality audio.

Yes and it has speaker-headphones selection. Very nice. I will be posting an optional update for 'RTKHDAUD.dat' with the AEC changes, and a setting I want to test on 887-892 for SPDIF.

DrvCtrl 43 -- 24-ForceRtkMicEftV2, is the only one I did not add, you might need to add it, I did enable RtkMicEftV2.

The preset includes stereo and multichannel, in fact 99% of it is stereo, either headphones or speakers.
When in multichannel mode you cant choose a stereo preset, or use stereo options.

1619446696368.png

That includes spatial modes, they are stereo for stereo.

----

Updated presets:
The Ferather one will be in the next update.

----

How to use the preset updater:

If you don't intend to modify anything, double click install. If you want to modify the .xml, do so first.
If you want to replace the APO4 preset (DTS:X), delete-replace the files in WIN10\APO4x\.

Make sure the folders are populated, else it will delete then install nothing.

Use which ever one(s) you like :)

----

Optional:

I just fixed an issue with noise and multichannel, by default SFX is being bypassed (APO4-Off), this causes popping.

Good to know, I cant see Zenith in the headphone list sadly.

----

Interactive:X is accepting 192khz 32 bit 6 channel input, output is 48khz 24 bit 6 channels (DTS standard).
To do 8 channels, I had to reduce the stream output to 96khz 24bit. Interesting results.

One more thing with this issue. Every time when start PC need to play around with realtek settings (change/reset default devices/communication) to start AEC work.
1619619199454.png

And maybe with headphone device adding/removing full range tick or maybe change/reset device format:

Should be fixed with the updater, the default driver has not got the extra options. Thanks for testing.
Edit: Just checked it, and it works for me without changing device after restart.

I did not enable DrvCtrl 43 -- 24-ForceRtkMicEftV2 in the updater, but are using it currently.
I have enabled RtkMicEftV2 in the updater, so I guess that setting is needed.

I will probably have to edit again the 'RTKHDAUD.dat', although as you said it's not important.

DrvCtrl 16 - 31-NoInternalSpkMic
DrvCtrl 39 - 19-NoInternalSpkr

Let me know if those changes make any effect.

I also found the above, maybe that helps with headphones.

Hello. You don't have this in the driver Inside the folder 'WIN10\APPS\UWP_Store\' you will find two .inf files, install them. How can I put dts ultra on Alan's mod? The link that you gave for the chipset 1200 is empty...

DTS DCH 6.0.9147.2 (Signed) - See post 1 here, for the download and guide. Added the above AEC changes, and SPDIF option.
Added DTS Settings, an optional download, which will disable-enable Interactive:X, and also setup HDMI-DP.

With Interactive:X off, SPDIF will enter 2 channel PCM mode, you can use spatial, so on.

----

@Zonder, See post 1 for the downloads, Alan should already have DTS:X Ultra working, no?

Can't you hear me? You have no path in the downloaded driver file-Inside the folder "WIN10\APPS\UWP_Store\" What files should I install there and how? Check it yourself
At Alan Dts ultra works but with an error - and it is necessary without an error.
