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

[Axel_Moore]

First image is correct if using SPDIF or HDMI, when in [multichannel] mode DTS is auto-configured. Else to use the modes and EQ etc when in [stereo], you need Speakers-Headphones.
Spatial is the same its for [stereo] only, not [multichannel], spatial takes [multichannel] and processes it for [stereo] (2 channel) speakers-headphones.

There is no such thing as multichannel spatial, certainly not via Windows. Everything you posted above is correct.

====

Note for everyone, If you unzip a package using built in Windows, files will get the blocked attribute, if you use 7-Zip files be as normal.
No idea why Microsoft has done it that way, but if you install, you will install blocked files.

In addition, you can run 7-Zip file manager as admin, and get access to certain folders without changing permissions.

It will also show hidden and system files by default, 5/5 app.

Thanks Ferather, let me ask you some more questions:

1 - Whats the difference, between, normal driver and alternative?

2 - Should i install Win CAudio?

3 - Should i play with DTS Settings zip?

4 - What does, the other .zips of the Settings and Utility folder? I think a mini guide would be nice.

5 - Can i send DTS signal, in stereo, instead multichannel, to my homecinema, to have this spatial options, available?

6 - How can i get my device id? I remember use FX Configurator in the past, but the new version in the folder, when i execute it, dont runs anything.

Thank you very much!

1: The ability to run on some devices, Main wont run on all devices.
2: That's optional, but I would, you get a better quality overall.
3: Not really, not unless you intend to use E-APO or add DTS to another device.
4: No guide, most of it is in post 1, the rest comes with a guide.txt inside.
5: You can send stereo, but its still set to 6 channels total (multichannel), not 2.

6: See below, sorry, I am told its not running on Win11, have not adjusted yet.



----

If you want to turn off DTS Interactive and use 2 channel PCM, set below to 0.
You might need to disable-enable the endpoint to refresh it after.

Thank you very much for your reply, actually im using 2 channel PCM bc my home cinema has lot of options, like convert stereo input to 5.1 that only works with 2 channels inpunt.

I was trying to install CAudio like you told, but when i try to add to reg the CAudio.reg it says "Cant add it bc registry key its in use or you dont have privileges" ... I just try to stop audio service and disable driver but nothing, the message its still the same.

Im missing to disable something? Thanks again.

you need to start regedit with the execti tool ( part of the caudio archive ) then import the regfile
Did you read the Guide.txt file?

Yes ofc, and i get this error... Thats why i ask.

Hmm that should work without any magic. Maybe your Internet Safe Zone settings marked that archive as possible dangerous. I dunno.
I use myself ( now since 4 or 5 years ) Powerrun from Sordum. That tool save every entry with custom settings which you have configured.

You can try this: Powerrun

Create a new entry like this:

and then execute.
Your Registry Editor should run with Trusted Installer privilegs. After that you can import the regfile like it is written down in the guide.
Maybe someone has an explanation which is easier.

Edit #1:

Here look at the different running user:

Thank you very much, now it works, can add reg keys without problem.

But i have a new problem, i cant use DTS in 2 channels stereo after install CAudio, only 5.1 DTS output... Any fix for this? Thanks.

 

[leveltrauma]

I'm sorry but why or who want's to use DTS in Stereo - that make no sense ( my own perception thats why I ask )
Because I never use it I have no idea. Maybe you can resolve it by using the Stereo.reg file @Ferather can you confirm?

 

[Ferather]

You can do it that way, if you edit the files and replace {DEVICE-ID} in both lines, then save it. You can disable SPDIF then double click to switch between Interactive or PCM out.

Sorry for the delay of the reply. I tought DTS quality 2 channels is better quality than normal signal. But looks that im wrong, bc you ask me that hahahaha.

You are correct, 2 channel [PCM] is lossless, 6 channel [DTS Audio] is lossy (not that you would notice), in both cases you get DTS audio processing (DTS:X Ultra), which is [PCM] processing.
To simplify, all audio processing hardware-software is PCM, the final output from an endpoint (in this case SPDIF) can be PCM or Encoded (e.g. DTS or Dolby Digital).

Previous to [DTS-HD Master Audio] and [Dolby TrueHD], all compression was lossy, the latter two are lossless, but only present on HDMI (at this time).
I can compare a 32 bit DAC and DTS Audio output, both are lossy (no such thing as lossless analogue), cant tell the difference.

If I remember right when comparing 2 channel PCM mode and DTS Audio, there was a difference in volume, but could not notice much of a difference otherwise.


I notice the difference between FLAC and MP3, with the same output, much more than I do with any of the above.

Uhhh nice. Wasn't aware you're a Citizen too^^
Love that game. I keep myself away from it most of the time. Waiting for a point in time when it runs more stable and more optimized. But from time to time I totally get into it^^

Just so you guys know, DTS has fixed the license bypass on newer files, looks like some of the changes are related to testing here (improvements).
I can still bypass licensing with the newer files, but they have additional checkpoints (check device matches).

In short, you wont be getting any DTS file updates as of now, I can reverse files and patch, but not re-write them.
If you have any Realtek related issues, please post and I will do a Realtek update.

----

Given the changes made, you wont actually gain anything or very little from the newer files, as long as the ones I provide work.
The driver certificate is valid until 2480, and can be installed and remain valid even after that date.

Could we perhaps consider a quarterly/semi-annual refresh of the Realtek audio driver to keep up with the ever-changing Windows 11 environment?

 

[Ferather]

Yes, 1-2 times a year, although I can only test win10 without extra steps (drive restores).

Unless there is a specific issue.

====

This package will still accept the newer license files (.lic), if you have your own already.

DTS Sound Unbound and DTS:X Ultra .lic files, entitle you to both products.
Ultimately you buy an APO4 license, which is split into two products.

====

Software processing using cpu-ram, beats audio hardware components.



Example, SFX could be used for lookahead no buffer.

If you are trying to find another source for the above, there is 5mm, 5mm pro, 6mm and 6mm pro.
Make sure the ad specifies pro (6mm), not the standard core, they all look similar.

Visual C++ package updated (14.40.33810.0), official link, here.

 

[Ferather]

The next Realtek driver will have additional features, it also looks like additional wireless support and additional endpoints have been added since I last looked.
No promises on an upload just yet, I am waiting for additional bug fixes before I make a new pack. I will likely publish 6.0.98XX.X.

 

[nicegirl05]

do you know whare to get dts neo pc by chance?????

 

[Ferather]

You will find it as DTS Connect, which is Neo-PC and Interactive. Pretty sure the APO driver has it, you wont like it though, its stereo expand (pseudo surround).

I would support it, but its rubbish, so just no. Use stereo surround (cloned, 1:1 bit perfect).

----

With this package, Neo-PC is managed by Realtek, and only enables if your device has natural support for DTS Connect (comes with).
The Realtek version can be turned off, it uses SFX and can also be replaced by Equalizer APO on SFX.

thank you for letting me know i ended up finding a vst for halo upmixer that works amazingly only issue is im useing the free version of bluecats patchwork so it stops decodeing for 1 seccond every min lel besides that working flawlessly would reccomend halo for upmixing

 

[Ferather]

Just to reiterate, you do not need to do anything special after installing the driver, provided you have completely followed the guide in post 1 (clean driver install).
I suggest using 'Win CAudio' * as it fixes several hidden Microsoft APO's that degrade audio, else 'Clean Listen' (DTS Settings).

I am not yet 100% sure if its Windows or GPU's that adds the 'listen to' code to SPDIF.


* You only need to apply the changes once per Windows install (check after major updates), effects all audio devices (global).

====



====

Test results with 'Stereo Mix' set to 'listen to' default output device (muted), and DTS in default mode.

Latency multichannel, final out: 10ms buffer (Windows) + 0.0ms = 10ms.
Latency stereo, final out: 10ms buffer (Windows) + ~2.4ms = ~12.4ms.

Stereo has additional spatial processing.

====

Enjoy 32 bit float processing, I added Realtek protection which allows up to around 150 dB with 24 bit devices.

It would be great to have these .reg files working on Windows 11.
I tried to understand their logic to update them, but I would need a more detailed explanation.
