I have a few messages from people who own a device with ALC1200, where they expected much better sound, and still end up buying a discrete or swapping to GPU.
A good sound card doesn't need 1 million APO's to make it sound better, usually one is enough if the PCM hardware is a high quality.
Nearly every sound professional will use and say to use a high quality discrete card, never do they say use onboard.
I really doubt any Dolby or DTS mastered content is produced by using an Realtek ALC.
----
The only thing ALC will never have an issue with, is bitstreaming encoded content, this is because its encoded and not raw PCM.
Because the encoded PCM is not read or sent as PCM, there is no PCM processing until the receiver.
Note, transcoding such as Dolby Digital Live, DTS Surround (Interactive), count as PCM processing, input is PCM from device.
PCM (from ALC, other) > Encoder > DTS/DDL out
----
Both Dolby and DTS are better off making an app on the store that allows you to buy Atmos, DTS:X Ultra, rather than bundled with ALC.
====
Funny after thought, If receivers where programmed to unzip a .7z file, then inside it can be a wav file, that is played back.
In short, this is how encoding works, where you take PCM, zip it up inside a container, and sent it to receiver.
Inside the container can be anything, this includes data, pictures, so on.
----
Personally I am waiting for OEM's to stop going back in time, Toslink supports 125mpbs bitstreaming (as mentioned can be anything, even Internet).
HDMI is now almost mainstream, its 37mbps for audio, yes, worse. OEM's don't support modern formats and current standards for Toslink.
Toslink, at full bitstreamrate, can do something like 108 channels, in PCM, limited only by the device producing PCM (total aggregates, etc).
Decoding an encoded format and then playing it back on a device that has poor PCM processing, downgrades the experience.
With better support, and improved programming, we should be able to directly bitstream PCM, no processing.
Also note, you can bitstream lossless formats down SPDIF, but you wont find a supporting receiver that has been programmed to accept it.
----
My ALC 889 SPDIF from 2008, can process PCM up to 1,152 total aggregates, this is 6 x 192khz, it can also do 8x 96khz (768).
The analogue direct portion of my ALC can do 1,536 total aggregates, this 8 x 192khz.

After trial and error, and technical assistance via DM + talk about the "modern" called APOs - I agree one hundred percent with your conclusion!

I went from Creative X-Fi Titanium Fatal1ty, to ALC 889, to AMD R7 via HDMI extractor.
1. AMD R7, the extractor is also high quality, no loss.
2. Creative X-Fi Titanium Fatal1ty.
3. Reserved! Just kidding, ALC.
Also note, I have not used analogue direct, or stereo for about 12 years.
In all 3 cases I am still using DTS Interactive, still better IMO.
----
Just noticed, Creative are still utilizing SPDIF, not HDMI with their newest products.
Sound Blaster AE-9 - Ultimate PCI-E Sound Card and DAC
It can PROBABLY send lossless down SPDIF, if-when any receivers come out.
It should be using 125mbps Toslink modules, which are compatible.
====
Is it me or is the whole 32 PCM channels on HDMI a white elephant spec? I don't know any soundcards that have more than 8 channels (7.1) as an option.
I also don't know any EDID that has more than 8 channels (7.1), all the EDID producing programs I have only show up to 7.1.
I'm going to go ahead and guess that its the same for receivers, 8 channels max.
--
The only thing I can find, is the 32 is based off total aggregate, 1,536 / 48 = 32, well any device with 1,536 can do that.
It also means any SPDIF with 1,152 total aggerates can do 24 channels, 1,152 / 48 = 24.
Still don't know any devices that will directly output 24-32 channels PCM.
Also note, total aggregates can be upgraded at any point.
====
HDMI: Max bitrate ~37mbps, max aggregate sample rate 1,536, HDMI can not go over 1,536 aggregates, not enough bitrate.
Toslink: Max bitrate 125mbps, max aggregate sample rate, currently 1,152, maximum = 5,189 aggregates.
====
I have also found, SPDIF its self, does NOT have a bitrate limit, there is no set limit, however Toslink and Toslink modules do.
So, all we need, its better understanding, better support, and some improvement to SPDIF aggregates.
I am able to send both multichannel PCM, and lossless formats using SPDIF.
ALC does not allow me to send multichannel PCM, but it CAN send lossless compressed.
My HDMI extractor does both multichannel PCM and lossless on SPDIF.
1. AMD R7, the extractor is also high quality, no loss.
2. Creative X-Fi Titanium Fatal1ty.

Just get a good HDMI extractor, it will give you GPU to SPDIF, GPU to Headphones, and GPU to HDMI.
I have not yet found one that does HDMI to analogue direct (4x 3.5mm).
I recommend a HDV-MB01, and this driver I made for it.
----
I modified the device, and added DTS Interactive, and DTS:X APO4, due to my receiver (legacy mode).
I am using SPDIF out, and as normal, the receiver only supports 2 channel, DDL/DTS.

How to send-test lossless [HDMI, SPDIF]
This is a simple guide to show you how to bitstream all modern formats using SPDIF, HDMI, or an HDMI extractor (HDMI > Toslink), and Potplayer. Firstly, please note, nearly all receivers don't support more than Dolby Digital Live, or DTS Surround in terms of Toslink (SPDIF). Most devices...

@Alan Finotty should be able to do what I did with DTS:X Ultra, and compile a .reg file that will add the details needed to run Dolby Atmos on USB, or usually any device.
The files will be installed and active since its in the driver pack, this allows us to program other devices, USB HDMI so on.

I used to buy Sony tech when I was 18-25. Phones, players, DVD, so on. Later they changed to other OEM's making their hardware, with Sony specs.
No real complaint against that move, but more OEM's became available, and some are far better. That's my experience.
There is also a SONY HDA APO, not that its supported much anymore by the look of it.

PT: Olá a todos e @Alan Finotty, Eu instalei o seu Mod e funciona tudo sem problema, exceto não tenho o equalizador no programa da Realtek e outra coisa que eu reparei, é que o serviço Construtor de Ponto Final de Audio do Windows "consome" um bocado do Processador, como se observa na foto.
O meu processador é recente: Intel Core i5 9600KF.
O que devo de fazer para reduzir esse uso de CPU?
Obrigado e saúde para todos

Hi everyone and @Alan Finotty, I installed your Mod and everything works without a problem, except I don't have the equalizer in the Realtek program and another thing I noticed, is that the Windows Audio Endpoint Builder service "consumes" a bit of the Processor, as you can see in the picture.
My processor is recent: Intel Core i5 9600KF.
What should I do to reduce this CPU usage?
Thank you and take care

@BillTaozi, check DTS APO4 Service is running in task manager, Alan has renamed it, no idea why. If its not running its being blocked by a VPN or similar.
If the VPN blocks the license service, the main service will shutdown, it will react as if you tried to hack or change IP addresses etc.
If you are talking about just 'Sound Unbound', the older provided app COMES with a license, if its updated by the store, you lose that license.
Disable 'Windows Store' automatic updates, and update your apps manually, skipping Sound Unbound.
I have a legit license for SU, so I don't use the older app, I use the store app (updated).

Restart the audio service.
Otherwise you could create an exception in your antivirus program for the audio service. It may help.
If both not help, then deinstall the AAF driver (p.e. with BulkCrapUninstaller portable) and clean the rest with DriverStoreExplorer.

Don't let Windows Store auto update all of your store apps (p.e. DTS Sound Unbound).

That's some good advice, they only thing I have that's negative, is third party driver remover applications.
When I used AAF, and it got stuck, DriverStoreExplorer, force remove broke Windows.
I also had a similar issue with original Realtek drivers, its not AAF strictly.
----
I have not used any driver remover apps, in a few years, I just use Windows pnputil (although it takes time if there is many).
Since using just Windows to install and remove drivers, I have never had any faults, with any driver.
----
If you dont restart your PC after removing drivers, you need to stop doing that. WINDOWS loves restarts.

If you deinstall AAF driver, then you still have driver rests.
So don't use DSE as an Uninstaller, use it only for cleaning the rests of drivers in FileReposity after normal deinstallation & PC restart.
And yes - you are right, sometimes you could get troubles, if you do something wrong with such a mighty tool.
Don't clean or (force) remove a driver, which is still in use! Sometimes there's no problem, only a warning, but with force it could hurt.
On the other side. Without DSE It's very hard to clean out the rests from AAF driver.
Alan Finote too recommends to use DSE: https://github.com/AlanFinotty/AAFDCHDriverMod/releases

NEW DCH DRIVERS RELEASED IN GITHUB
DCH DRIVER VERSION UPDATED TO 6.0.9209.1
MORE DETAILS IN GITHUB
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.
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: This driverpack isn't eligible for USB-based Realtek audio chips.
RECOMMENDATION: 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", "Dolby", "DTS", "Creative" or "Alan Finotty" 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), select your decoder and deselect the rest.
If Dolby Atmos again insists not to install, here are the packages for installation.

ENJOY!!!

@Alan Finotty, with a script, you can stop the Realtek service, as task kill the Realtek task (both have the same name: Realtek HD Audio Universal Service).
You also stop 'audiosrv' and then 'audioendpointbuilder', at this point you can delete and replace files, using cmd code.
Essentially you can update the files without re-installing, if written correctly.

Hi,
First, this is an amazing work ! thanks a lot
I encounter strange problem while i am trying to install AFF on my new build :
First try = i got sound via SPDIF OUT but DTS Interactive was not activated
so i uninstalled everything and used also DSE + uninstall my VPN and disable Fast Boot
Second try = everything now is activated (DTS Interactive + Unbound + Ultra + Dolby Atmos) but no sound from SPDIF :/
When i am going to SPDIF properties, i can't even play the sound test and i get an error message "we couldn't play the test file"
I tried to uninstall NVIDIA sound driver in case of conflict but still the same
Could someone help me please ? Do i have to install Realtek in Legacy maybe ?
For you to know, i did activate the dev mode in settings and each time i'm trying to instal AFF i am starting my pc with Driver Signature Enforcement disable

Yes some VPN's and restricted internet services can block live licensing, and the DTS APO4 essentially turns off, its roughly like it reacts to wrong IP or location, or hack attempt.
@Mitras, that's sad to hear, I dont program Alans driver, but try changing the format, it might complain, but then hopefully fix its self.
