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

[vsdfg]

I solved by installing dtsx with alan package and then your files in system32/dts, but any of the presets and effects are very bad. Considering I have an SS3 motherboard I should stick to that. It's bad but not as apps from alan's package (well except sonic studio but at that point I'm better served with mokichu's)

 

[pyuras]

@pyuras, yes, use 'DTS Settings' from the main directory, and apply 'Stereo' to the headphones, if its a USB device, see the second part of this post.

Actually, my headphones are connected to the front panel of my case, it's not a USB device.

I have a USB headset (the PS5 one) and it works perfectly.

On Alan's driver I can just select the phone on windows devices to switch to my front panel connected headphone. Is there a way to do something similar with your driver?

 

[Ferather]

@vsdfg, the presets are not great but the OEM ones are not generic, I have made my preset as generic as possible. Did you try my version? I am guessing you used AAF-Other?
@pyuras, normally I just separate headphones from shared to individual endpoints, using 'Device Settings' in the Realtek app, which does not need programming.

If I separate headphones from shared, the endpoint is already built according to the driver, which includes DTS APO4.

----

@vsdfg, some further thoughts, I am happy for you to use the 'OEM-Laptop' files, I would guess DTS stopped supporting those OEM configs due to programming and overheads.
However, if you are using AAF or another DTS preset, you should ideally complain to them so changes are made, for example Acer if its an original Acer preset.

You can thank @Bryan Ü, for testing and archiving those files, personally I am using a mainstream device with HRTF support, and more features.

As a side note I have noticed some of the newer Asus presets are almost identical to my own, I can also see which FX they turned off.
If you are lucky with whichever Asus models use those presets, you should end up with a preset similar to my own.

====

'DTS Settings' is to program third party devices (not Realtek), for example AMD GPU (HDMI), USB-Bluetooth Headphones, and some virtual devices (such as virtual audio cable).
All Realtek related endpoints are pre-built, this includes SPDIF, Realtek HDMI, Realtek Bluetooth, and so on, no programming or extra steps are required.

The 'Preset.reg' is more to quickly reset the APO registry data on that endpoint, DTS APO4 will already build this for you on each endpoint.
If for example a USB device is not working, even after applying 'Stereo.reg', it will need to be converted to 'HDAUDIO'.

'DTS Settings' can also be used to toggle DTS Interactive on-off on a digital endpoint such as HDMI-SPDIF.

----

Feel free to tune or change the preset, if you want to view or tune the one installed, open the .xml file, ideally tune it to your main device.
As mentioned I have made it generic as possible, focusing on both quality and speed (even stereo is instant with effects on).

For the better part use 'Music' or 'Automatic', the other modes are intended for their purpose.
Each mode is nearly identicle in setup, the major exception is the spatial mode.

====

Here is a quick guide to fully initialise DTS APO4 on digital interfaces:

> I Noticed a bug with DTS APO4 and digital interfaces (not officially supported), if you stop the service and then restart the computer, it forgets and does not fully setup.

I am using the 'External Speakers' optional on SPDIF, however, first switch to 'Speakers' (analogue), then open 'FX Config' and 'Regedit'.
Using 'FX Config' to get your devices GUID, in 'Regedit' navigate to: 'HKLM\SOFTWARE\DTS\APO\{DEVICE-ID}'

Set the 'initcount' count to 0, then switch from 'Speakers' to SPDIF or HDMI. DTS should now configure as 'External Speakers'.
This change is permanent unless you stop the service and then restart your computer, as mentioned.

Interesting.It is not even lauching for me

@Ferather it has lisence too.​

 

[MichiW]

Is the Realtek Audio Console in the package included?I have activated DTS Interactive but there is no Audio Console or something like that

you can just download it from microsoft store but he has the app in one of his download links under additional apps

 

[Ferather]

@MichiW, You can see the apps folder in post 1, or download it manually, see the manual guide in the same apps folder, as mentioned by @ajf64 (thanks for your post).
See the provided 'RTK Panel.txt' to modify your ALC policy* (policy edit tab, at the bottom) and add full support to the Realtek Console.

@Bryan Ü, noted, if you get it working lets us know if you find it better with your headphones, or earbuds.
Not all headphones and speakers (and even ALC) are the same, and vary.

i got your back buddy

 

[Bryan Ü]

i only see black background after logo.
even after deleting some files.

lets see which type of software dolby create after uwp being disappearated.

 

[Ferather]

Currently I am away from my main computer for another few weeks, but I will take a quick look at the official Dolby system and driver when I am back.
I would guess the license part you posted is more like a license service, which validates a license on the system.

Direct UWP manipulation is near impossible to do, its very well designed.

It came preinstalled on Surface Book 3 according to user.
unfortunately i cant download driver am low on data.
@Ferather
Use MSIX Hero to run uwp app manually/ from its entry point.

 

[Ferather]

I am still on a break from drivers and driver packs, however as you all know its not urgent, as there are no major bugs.
If you would like to update the DTS APO and tech files manually feel free (stop all audio services).

Also feel free to personalize the DTS preset .xml file, its unlocked on SPDIF-HDMI.

E-APO VST Stereo Upmixer - By: @itsalic

 

[Ferather]

I noticed the other day, with analogue 5.1-7.1 (multichannel), and opening Sound Unbound, it will by default enable stereo spatial (Ultra for stereo).
Windows it's self has a coding fault, where changing to spatial from multichannel sets the device mostly to stereo, but not fully.

It sets the SFX, MFX, EFX correctly to 2 channel, but does adjust the number of attached speakers in the registry.
If you open the Ultra app, it will still display 'Multichannel' mode, and you may get audio issues.

I will post on the Microsoft forums, I have noticed it also happens on HDMI via the right click menu (system tray) on Win10.

 

[Bryan Ü]

any idea what this is?

 

[Axel_Moore]

I just test all kind of drivers to enable DTS 5.1 or DDL 5.1 and nothing works for me, except this DTS DCH Driver for Realtek [DTS:X] from Feather.

My hardware its:
ALC887/897 - Realtek 7.1 Surround Sound High Definition Audio CODEC* https://www.asus.com/Motherboards-C.../TUF-Gaming/TUF-GAMING-Z690-PLUS-D4/techspec/
Yamaha RX-V659 connected via S PDIF.
Windows 11.

My questions are:

1 - Its normal that i cant use spacial sound ? When i select it it backs to disable.

2 - I just only install the driver and nothing more. Should i use DTS Preset Installer.7z or DTS Settings.7z ? Anything from TOOLS folder too? To improve my audio?

3 - How can i enable DTS 5.1?

4 - Would be possible add Dolby in future release?

Thank you very much for this work, as i told you its the only driver in internet that works for my setup.

 

[emanresu]

Thanks to the brilliant @Ferather I have started a live web radio stream with a Universal (Re)Mastering Chain applied - you can hear it in action here: https://y.dog/yDog

Dat DTS:X Ultra. Also special shoutout to 2 other guys who enabled Ferather

 

[Ferather]

@Axel_Moore, sorry for my late response, I have been busy recently.

1 - On SPDIF, yes, DTS Interactive is 5.1 for digital out (SPDIF, HDMI)*, the Sound Unbound spatial modes are for stereo only (2 channel).
DTS:X Ultra will apply multichannel effects to SPDIF, HDMI (and analogue), the app will display that its in multichannel mode.

2 - To improve your audio, no, they are used optionally, you could use the 'External Speakers' package on SPDIF.

3 - Its already enabled on SPDIF if you have selected 'Main' as the install, else its set to stereo on 'Alternative'.

4 - Possibly, as a separate extension package, not part of the main driver.


* HDMI audio is SPDIF, just another type of connector, like coaxial. Extra note, you will hear 8 channels with 6 speakers (Interactive).

For best audio experience, and lowest possible delay, use optical, with the right modules it can do up to 125mbps.

 

[emanresu]

I think DTS folding is 1536kbit/s * 8 then? Should be something close to 125 mbps/s which is max, like you described

 

[Ferather]

It's downmixed to 6 channels pre-encoder, so DTS Interactive is still handling 6 channels as normal. Hardware spatial.
Also note the final bitrate of an encoder, and the final bitrate of SPDIF-TOSLink are not the same.

SPDIF - Sony/Philips Digital Interface

Decided to post some info I found. ---- S/PDIF (tech-faq.com) - "Although the SPDIF protocol doesn’t specific a max resolution or data rate, the equipment which uses the SPDIF connectors has to determine the data rate..." S/PDIF - Wikipedia - "...has no defined data rate. Instead, the data is...

Thank you very much for your response, yes my yamaha detects 5.1 dts signal and i can boost 2 channels stereo content with sorruound enhanced to make it 5.1 adding Dolby Pro Logic IIx.

Could you explain me what does DTS Preset.reg from you settings and utilities folder?

 

[Ferather]

That's not really needed at all, but its there in case you edit the registry. It sounds like you want to tune something, hehe.

You can edit and modify the preset.xml, found in 'C:\Windows\System32\DTS\PC\APO4x'.
Cut the file, then paste it on your desktop, edit it then replace, and restart.

In general, once you have installed the driver, there is nothing special to do, unless you want-can unlock the Realtek app.

 

[Axel_Moore]

Ok! Thanks.

Hello, i’m not a newbie since i already installed the whole driver a lotta times.
I need advice for what concerning audio configuration.
My purpose is to have a fully 7.1 setup on my headphones (AKG k612 Pro) + better sound quality through my Hi-Fi (Denon AVR-1705) 6.1 Receiver + Bose Acoustimass 5 series III (2.1).
What configuration you advise? I’m currently Running on 48000 Khz 24bit for having the Spatial Audio DTS:x Ultra , but i noticed that using Dolby Digital (supported by my receiver) The audio quality is better.
My problem is that i have to connect my headphones onto my Receiver, because if i set the Spatial Audio on the Headphones in windows 10 the volume is so low and i actually have not the money to buy a whole amp for the Heafphones .
Can you suggest me a configuration?
Thanks a lot for helping me . Bye

seems the head phone port on your pc has a low power dac most likley an easy fix would to just get a half decent usb dac and plug that in to your pc
