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

[Ferather]

They work on Win11, its just the FX Config that might not run on Win11. You just edit the files replacing {DEVICE-ID} with the one you get from FX Config, the alternative is the screenshot I provided.

Copy that to notepad, the highlighted bit is the GUID.

Also make sure you install C++ with Win11.

====

What device are you trying to add DTS-Realtek to? You may need some extra steps if its not HDA.

====

If you are missing the Realtek startup task (rare), you can simply add it with a .reg file.

 

[Ferather]

Post 1 updated slightly, added a note about Windows extract and files, added an image of SPDIF with 6 channel PCM mode and DTS Interactive, full multichannel mode.
I suggest 7-Zip, its free, widely used and supported, you can also right click and run its file manager as admin, and gain access to 'certain' folders.



You can also setup the context and file formats as admin.

----

Additional guide for expanding DTS-Realtek to another device, in most cases if its speaker-headphones it will show in the Realtek app.

If you would like to expand DTS-Realtek to another device, use 'DTS Settings' (Settings and Utility). You may also need the additional registry guide below:
Usage: Edit the relevant .reg file, replacing {DEVICE-ID} with your chosen endpoint in both locations, save, double click, restart.

====

Note, when I specify Realtek, you will be looking for DTS DCH instead with this driver pack.


I will use VAC as the endpoint to change (old images), open 'Regedit' and go to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\MMDevices\Audio\Render
Find a Realtek 'HDAUDIO' device on the system (left side in Regedit), it can be any Realtek endpoint that says 'HDAUDIO', I used Realtek [Speakers].

Find and copy the value of [ {b3f8fa53-0004-438e-9003-51a46e139bfc},2 ] from [Speakers], replace the value on the [VAC] device.
Next, change [ {a45c254e-df1c-4efd-8020-67d146a850e0},24 ], to 'HDAUDIO' on the [VAC] device, then restart.

VAC with the two above changes + DTS Settings (also shows in the Realtek app).

----

In some cases you might need additional permissions to edit the endpoint, use ExecTI to run 'Regedit', then you can edit entries and import .reg files.

DTS note, to change modes when using 'stereo mode', you need the form factor external-internal speakers or headphones.
When no supported form factor is detected, multichannel is as normal, stereo is in default only mode.

 

[Ricardo Fernando Ferreira]

When the DTSEnabledInteractive option is set to 1 in the registry, most applications and games work well in 5.1.
However, I can't set the DTS Ultra option as spatial audio, when I try, the box simply reverts to "Off."
In fact, I can't select any spatial audio option.
Several games, like Resident Evil 4 Remake, block the spatial audio option when none is applied to it.
Am I doing something wrong?

 

[Ferather]

No, spatial audio is for stereo only, not multichannel. DTS:X Ultra will display multichannel mode, and in automatic configuration.
You wont be able to select any stereo spatial modes, unless you disable Interactive and set stereo out.

It's correct that Interactive will intervene and switch back to multichannel (6, 5.1).

----



Entry 7 is created by DTS APO4, its optical in multichannel mode.

----

Optical: Spatial APO (DTS) > SFX APO (DTS-Realtek) > MFX APO (DTS-Realtek) > EFX APO (DTS).

Note that [DTS:X Ultra] is an APO system, PCM processor (12+ Ch).

kinda cool also kinda scary to share around as anyone could create a certificate to a application that can cause serious harm to a pc

 

[Ferather]

You don't need a certificate to damage someone's computer with software, how many times have you run unsigned apps as admin?
The certificate mostly just shows the user that it has not been tampered with, after signing.

----

An example is: Download Device Cleanup Tool - MajorGeeks (useful)

This .exe is signed by the author, if you right click the .exe you can see its signed, but not valid because the cert is not installed.

When you right click run as admin, you will get a yellow window with no signed author.
I resigned the .exe with my own cert, now its a blue window with 'Ferather'.



An invalid signature is the same as no signature.

i think your missing what im saying yes u can do damage without this just as well but if ppl see this it could trick someone into thinking its a untampered application when in fact it is tools like this are not widely available for a reason because if everyone had this every application would be certified safe basically causeing this to no longer be a effective form of security

 

[Ferather]

Its already not an effective form of security if the author has to install a certificate in order for the files to be valid. My point was plenty of authors self sign files, but don't install the public certificate.
I could sign a virus, but that wont stop your AV from scanning the code and flagging it, then take steps to remove it. Signing files wont make the virus work.

The catalogue used in driver installation has to be signed, this is just part of Microsoft system, else it wont install.
You can also disable driver signing enforcement and install an unsigned driver.


Also byte patching an original file, you can only change bits (r15 to r14), not re-write or inject code.

====

Both my packs run in code protected mode, if you install something like Equalizer APO, you need to disable AudioDG protection.
As a side note, the DTS:X Ultra pack is not a driver, it does have a software component, but its not a driver.

Out of curiosity would you prefer the driver was unsigned?

valid point of veiw and tbh id rather just use offical solutions if i can help it as most drivers are meant for older hardware which im no longer useing at this time its also safer lel as i did have a scare awhile back with a apo driver and windows flagging it as a tampered program however i do have to ask why do u call your solution dts if its really pcm with meta data dts needs dts hd ma as the bace to hold that meta data dolby uses pcm to hold meta data but mainly in vedio games with dolby mat

 

[Ferather]

All those digital formats are just compressed PCM, no different to 7-Zip or WinRAR, companies can call their tech whatever they like.
Also a good reason to stop using MP3, its lossy compression, imagine this driver with 'lossy' compression, lol.

Its also the same thing with analogue, no analogue system is lossless, even an analogue CPU is inaccurate.

Bit-perfect FLAC or don't bother

----

With upgraded SPDIF - TOSLink and a DMAS (digitally managed audio system), compression is optional, PCM is standard.



In this case the digital device (1st), can decode compression back to PCM.

RTN digital transmission is real-time bit-perfect (bitstream).

for dolby mat yes this is true but for true hd digital plus dolby digital dts etc thats not true starting with object baced surround codecs those do not use pcm unless its live encoded again useing dolby mat for movies music tv etc that is not just pcm with extra encodeing but actual dolby and dts tech we know this because pcm cannot transcode dolby or dts the only way to do that is with ieee float thats due to the encryption used to tell the avr hey im dolby or hey im dts aswell codecs like true hd and dts hd ma have way higher sample rates than pcm so it would be rather difficult to do this

 

[Ferather]

Nope, all formats decode to PCM in terms of audio. I will use 7-Zip as an example again, lets say you had a .pcm file and a metadata.txt file, you compress to .7z with max compression.
Now you send the .7z (bitstream) to the AVR, the AVR extracts (decodes) the .7z, resulting in a .pcm file and a metadata.txt file. PCM > DAC > Amp > Speaker.

All formats can already be sent down anything with the bitrate to stream, when in passthrough mode HDMI-SPDIF uses a PCM stream to send all data.

Representing Formats for IEC 61937 Transmissions - Win32 apps | Microsoft Learn

Now lets say you had the current consumer standard (updated) SPDIF, which is 15+ channels, it can set the 8 x 16b 192k PCM stream needed to bitstream (passthrough).
The legacy SPDIF, still used at this time, but now superseded by the current version, uses only a 2 channel transmitter, and can not set as 8.

----

If you played an MP3 or FLAC via a media player (which no doubt you do), its decoded to PCM and sent to hardware as PCM, same for Dolby-DTS (if you have decoders).

In order to get a 16 channel AVR, you need 2 x 8 channel DAC's, since I am not aware of any 16 channel DAC's, plus you need a 16 channel analogue amp.

----

102 x 24b 48k = 117.5 Mbit/s | 8 x 16b 192k = 24.5 Mbit/s (~ DTS-HD MA max rate) | 2 x 24b 192k = 9.2 Mbit/s | 2 x 16b 48k = 1.536 Mbit/s (DTS max 1.509 Mbit/s).

Not 100% sure of the PCM stream for DD Plus and DTS HRA, but [2 x 24b 192k] would cover both.

----

Both DTS and Dolby offer compressed storage, and smaller bitrate to do more channels, bits or samples, however with a DMAS, DTS-Dolby are just PCM processors.
Not saying a DMAS can't support decoding like other AVR's, but with 102 channels, and the right bitrate, why send compressed at all?

There is no DAC or analogue amp in a DMAS, you can totally blame your speakers for any loss.

----

Side note, 2x frequency = sample rate, human hearing max ranges are 20Hz to 20kHz, which translates to 40kHz sample rate, above 48kHz digital is not worth it.

52 x 48b 48k = 119.8 Mbit/s, TOSLink high-speed modules: 125 Mbit/s (NRZ-PAM2). BMC is bitrate heavy (and old), RTN is bitrate light.
102 x 24b 48k = [117.5 Mbit/s] | BMC: [235 Mbit/s] required, RTN: [123.3 Mbit/s] required, RTN fits in [125 Mbit/s].

CPU/RAM (Device) > SPDIF (RTN) > TOSLink (125) -- TOSLink (125) > SPDIF (RTN) > CPU/RAM (DMAS).




Example: 100% power (bright, 1), 50% power (dim, 0), 0% power (off, -), return to nil (-).



The upgrade should be called SPDIF 2.0.

Reminder, buy a Sound Unbound license to support DTS, and DTS PCM processing technology.

Optional:

I have edited the current release, in preparation for 6.0.98XX.1, and to make things more tidy. I have set all relevant capture devices to 24 bit default.
Please note, Realtek seems to add 24 bit to capture formats after default endpoints are built, meaning 16 bit is selected.

[Ferather]

Here is a backup of Potplayer and configuration (.reg) files. Its set to decode all supported formats (MP3, FLAC, DTS, Dolby, so on) to [PCM 32 bit-float 48k].
The 32 bit-float PCM audio will be processed by DTS:X Ultra + Realtek, then output as PCM (or encoded then output via SPDIF).

Float decoders are prioritized, KS devices are detected. Use WASAPI exclusive if needed (passthrough).

[Ferather]

Currently I am working on a full DTS APO4 update (all files), no promises as they have changed a fair amount, and some of the changes make no sense.
For example the newer APO4 service sets 'Internal-Speakers' instead of 'External', which seems like a bug but they all do it.

I am also using a new IDA Pro, I have found a viable update, and are working on it, but its not the latest.
The newer service I can modify to set 'External', but I prefer not to over mod.

----

Autodidact, machine code reverse engineering.

 

[Ferather]

Unlocked and fixed, I also have set 'External Speakers' as the default used when a non-supported form factor is detected (SPDIF-HDMI).
No idea why DTS keeps setting '5.1 Surround' as 4 channels, I set it to 6 correctly, plus some other fixes I found.

Just need to change the 'Internal' to 'External' in the service, when I find the direct code for it.





----

Don't worry, all the fixes are in the current release.

----

I would vouch for DTS running on a DMAS.

 

[Ferather]

Be wary of speakers that go beyond 20kHz, and charge more money. I have seen 40kHz speakers, which are a waste of time, money and bandwidth.
There is so far no proven information as to why you would want audio played at beyond the human hearing range (20Hz - 20kHz).

Aside from not being able to hear a single bit of it past 20kHz, you would need audio sampled at 88.2-96kHz.
This is a waste of processing, waste of bandwidth, and a waste of money in whole.

Most sound systems (DAC, Amp) are rated at 20Hz-20kHz (or around), good luck getting 40kHz in the first place.


Over 48kHz sample rate, is a white elephant spec, unless we are talking analogue to digital aliasing.

More fidelity from bits and high bit depth processing.

----

Note, some AVR's use 32 bit processing (fixed, not float) then a 24 bit DAC. Would be better if it was float, but regardless, better processing.
The difference between 24 bit fixed and 32 bit fixed, is not as obvious as the difference between 24 fixed and 32 float.

My DMAS design uses 32 bit float, and 32 bit float speaker out, speakers utilize 32 bit float.

----

If you own the Logitech Z906, there is no DAC, its Class-D 48 bit digital (digital input, SPDIF). DTS 24/96 is supported. 110 dB SPL.

 

[Ferather]

DTS Settings, updated. You only use them on devices that don't currently have DTS-Realtek, or to switch SPDIF-HDMI between DTS Interactive and Stereo.
Use 'Clean Listen' if you need to remove the added code some GPU features add to endpoints, disable > apply > enable.

 

[Kabal81]

Will the new driver bring some new features or benefits with it?
Anyways, keep up that great work!

 

[Ferather]

Bug fixes no new features. I doubt there will be new features tbh. I will look at the latest files once I am done with the ones I am working on, to see if there is new features.
The main bugs I am aware of are in Custom mode, spatial mode is missing a refresh on change, bass boost can be odd 1st time use in some cases.

Using the newer service alone, seems to have fixed the spatial change refresh, but not the boost 1st time use.

For those interested: https://www.mediafire.com/file/q4l7mf0g3d63bbo/DTS_DCH_APO4.7z
Should only be Internal to External Speakers in the service to do.

Also note, if you are interested in making your own Realtek driver pack, feel free to use this one for reviewing (learning).
I have moved the updated optional (#1,964) to the main directory and replaced the previous version.

[Ferather]

If you need file sources, use the Microsoft Catalogue, you can use year in the search if needed (and sort by date), examples: DTS 2024 | Dolby 2024

I will get back to looking at the service soon, I might try a newer version to see if its external by default, and test it.

 

[Ferather]

Ok, so if you are searching Microsoft Catalogue, use the search terms 'Vibranium XXX Year', for example: Vibranium DTS 2024.
The package will be listed as 'Vibranium and later', so Win10-Win11, instead of just 10 or 11.

Also I will play around with the latest version linked above.

----

I successfully unlocked the latest 2024 version, all features working, same issue though, 'internal' instead of 'external'.
The registry structure and data has changed a fair amount. Hopefully I can post an update.

Just created a private, but sharable, unlock video for those interested in other files (Dolby for example).

Message me, if you want the video download link.

----

 

[Ferather]

Ok so general testing passes (DTS APO4 2024), it should be a case of everyone can use main from the installer, but that is not yet tested fully.
Based on my preset, and without change, SPDIF is supported as 'External Speakers' by default, (DTS read my feedback).

I will still remove the unknown section in the codec, they also still set 5.1 as 4, so I will have to email DTS directly.
The only change to make, is to change the new default of internal, and some further testing.

----

Note, in the event Realtek update SPDIF to current consumer, and some Windows updates, DTS would support 15+ channels (12, any).
In the event of the update, you will be able to passthrough all formats, up to 62.5 Mbits/s BMC (125 Mbits/s TOSLink).

The will be a new model (if any), since the current ALC's have 2 channel transmitters/receivers (hardware).

----

 

[Ferather]

Ok so all working, the newest version is so far the better coded version, I wont explain in detail, but reading through I can tell you they have improved their coding.
The service no longer comes with libs, and based on the size difference DTS are using their own code, and not libs as much as previously.

The DTS services loads more into memory, but this is due to the code changes, the audio engine is using less resources.
Not really sure why they have defaulted analogue to 'Internal', initially it runs as 'External'.

SPDIF is working as intended without any code changes. The 'Internal' to 'External' as default for analogue is the only thing for me to change.

----

Latency has improved with stereo, and also SPDIF but I cant really tell with SPDIF, audio quality is also a bit better (DTS DSP improvements).

----

The registry data store is structured very differently, with isolated SFX, MFX, EFX, entries.



USB is supported (in code), but not yet fully tested.
