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

[ToniM_8]

Crap
windows want to download audio drivers

same

 

[Ferather]

@Gil80, Do you have an older extension? It should only download two software components, one for Ultra the other for Headphones:X v1. I have no updates to download!

Edit: Hmm, never mind it must be part of the Realtek package, How to disable automatic driver updates on Windows 10 | Windows Central
Edit 2: Did I somehow unlock your PC, or do you normally have a DTS:X driver? It looks like its downloading DTS:X.

----

New Preset:

Optimized stereo and multichannel, its now a combined preset. Added 5.1 to external, for those who want to add EFX 5.1 to analogue (already present on SPDIF).
No more popping, or at least its very rare or unnoticeable. Improved performance, now almost instant in stereo mode, and faster with spatial on.

Altered 'Internal Stereo', keeping its optimizations, but changed to better suit performance, even with spatial on.

Is it possible to have BOOM 3D and DTS X Ultra app working ?

 

[Skylined]

@ Ferather

I tried your new preset - it's much clearer and very nice in spatial mode

many thanks

 

[Ferather]

You are very welcome, I just made one more final change (link updated), and added distortion protection and anti-clipping to EFX 5.1.
Slightly cleaner, slightly better quality. This preset will be part of the next driver update from Realtek.



Thankyou for testing, much appreciated.

I only have DTS drivers since I started to use your mod driver. I don't know what's going on.
I used gpedit.msc to disable driver updates for now.

I'm now a bit confused with all the files you kindly provided. I hope it's not troublesome to ask what should be installed and in which order.
That's what I currently have downloaded:

1. After following your OP to clean .inf / drivers, I proceed to install DTS DCH 6.0.9147.4 - correct?
2. Then I install DTS DCH Apps - I chose DTS Ultra and DTS Unbound - is that OK?
3. I then install DTS Preset for Ultra - is this OK?
4. Then I install DTS Preset - this was downloaded today - is this OK? Does it make step 3 redundant?
5. I then install Policy Install.
6. I didn't use DTS Settings - I don't know exactly what it sets.

I'm using only Stereo speakers and stereo headphones. I don't have multi-channel setup.

 

[Ferather]

Yes you did it perfectly. Let me know what well Headphones performs, I was thinking last night I might be able to apply changes there too, but they will be with the next Realtek update, unless urgent.
DTS Settings, is for those who want to modify SPDIF into stereo, or to add Ultra and Sound Unbound to HDMI-DP (USB, Bluetooth, and sometimes other sound cards).

I must have unlocked your device, I can see its downloaded the latest DTS driver, that's nice to know

 

[Gil80]

What does it mean?
How does one unlock a device? Is it a good/bad thing? Not sure what's going on

 

[Ferather]

My guess is Windows thinks I am an OEM, and tried to install a DTS driver suited to your chip. Its a good thing, its means you should ALWAYS be able to install a custom DTS driver, and be compatible.
Technically the OEM is DTS, with me as the digital signer, the driver has also been setup as OEM, although I am not 100% sure what unlocked the DTS download.

I suppose its a bit like an upgrade from ALC to ALC Pro, for example ALC 889 to ALC 889 Pro.

----

I was bored, so I decided to do the optimized headphones codes, should have more performance (even with spatial on), and better sound.

@Zonder, @Skylined

Welcome. I put an updated preset. Testing it. It would be great if it was written what exactly was changed. For Dts ultra in spatial mode is very cool.

 

[Ferather]

List (not in order):

Optimized effect points (SFX, MFX, EFX), activated-deactivated based on the preset and effects used *. < Increases performance, even with the Sound Unbound spatial engine.
Activated 5.1 end effects for any drivers using the EFX 51 class ID. < In the case of DTS DCH, this is being used alongside DTS Interactive.
Trimmed 'Internal Speakers' effects to improve performance, whilst maintaining internal optimizations.
Added distortion protection and anti-clipping across the board on all devices.
Enabled Ultra:X spatial modes, using SFX, MFX, (stream, mode).

* Headphones, Stereo speakers and multichannel outputs are all optimized.

----

Something you can try (will only work with Alans driver if he has registered EFX 51), from, to:





DTS_EFX_51_CLSID = "{1AAB27FA-5B3E-4CB1-9312-C66BD74FE739}"

Forgot to say thank you for the feedback.

 

[Skylined]

@Ferather

You are the man. You're really good at this, the preset keeps getting better and better - I'm using it now and the improvements are easily discernable. Thanks a lot.

 

[Ferather]

Lovely, thanks. So now I should have officially no changes to make other than update the files on new releases.
After the next release from Realtek, any further updates will be optional.

 

[Kabal81]

@Ferather
Since the thread is grown to 15 pages now, I think you should bring the initial post up to date. With all these little tweaks hidden in 15 pages...
I think a little step by step installation guide would be useful? Something like Gil80 did in #364
And of course to cover the presets and stuff.

 

[Ferather]

Sure, here is an up to date guide (edit rights have a timer, I am sorry):

Follow post 1 to fully remove any current, and past installs of audio drivers, this includes any bundled apps.
When using pnputil, look for class: audio devices, signer name: DTS, Ferather, Alan Finotty, Realtek.

Once the driver is installed, you can install your driver policy if already made, install the one I provide, or create one.

[Gil80]

So based on my previous comment, do I need to wipe and start from scratch? Or can I override existing stuff? What should I install now?

 

[Ferather]

When I update, because my only past install its DTS DCH, I just right click uninstall, in 'Device Manager', I tick delete driver, as say no to restart, I then pnputil just the extension.
After that, and still before the restart, I run CCleaner to clean the registry about 3 times, until the results box is empty, then I remove apps, and restart.

Also unplug your internet, and-or disable automatic driver updates from Windows, and apps from Windows store (manual download and install).
Also note, as of DTS DCH 6.0.9155.1, if you install a driver policy, it will not be removed, and does not need to be installed again.

If you install another driver which uses a policy, your one will be overwritten and removed on uninstall.

Great mate. Thx for this

 

[Ferather]

Make sure you just double click 'Install', it has codes to remove past install data for DTS and also any added presets or files not included with the default driver.
You will notice you can turn off Ultra without it bugging, it will turn on at the last preset you selected, all working as intended.

----

I forgot to mention in post 1, that if you want the digital decoder to stay always on, enable stereo mix. Set it to play to digital, and then mute the stream, this will make your receiver stay on.



----

If you DONT get 5.1 audio when playing 5.1 or 7.1 audio with SPDIF and DTS Interactive, you can try the following setting using the tool.
Be aware this setting can cause BSOD on some ALC's and setups, its not needed if Interactive is already working.

DrvCtrl14 - 27- CHConfigWithSpdifOut << Channel configuration with SPDIF out.



Both analogue and digital need stereo upmixers, such as E-APO.

Multichannel 7.1 and 5.1 Wav Test Files

----

@Hearick, sorry I somehow missed your post, without trying it, I would say yes, it should hopefully be like Equalizer APO in the way it adds its self in setup.
If setup correctly, both DTS:X and Boom 3D should work at the same time, again I have not used the app so I don't know for sure.

----

The new Ferather preset which will be default in the next update is approved by a few audio remaster's, and driver authors.

----

Updated, added additional options to EFX 51 (special edition).

Nice work the driver worked for me too. By the way driver was working fine for me without the policy. But i copied your policies and driver stopped working. Later i used policy maker tool to create my own policy. By the way has rltkhdaud.dat is still flashing.

And the driver are well configured i felt more comfortable/effective with your driver + HP settings than NON DTS HP driver + HP settings + DTS extensions.

 

[Ferather]

You are welcome, the policy I am using is totally optional, I suggest making your own as it will use your OEM settings, which you can then add to (see the .txt file in /TOOLS/).
I suggest testing the new Ferather preset, you can view (well hear it) before I release it as default with the driver, and send feedback so it can be tuned.

For SPDIF, if a format is not supported, it will transcode to DTS-HD HRA.

 

[Bryan Ü]

I dont think i will be able to compare your settings cause i dont really have good headphone. But i think you have focused on the voice and surround sound.
I usually listen to music and play shooting games.

Personal preference
Music Mode: It should be warm and it should pop out the details a bit.
Shooting Mode: Sound separation should be the high priority with good sound stage.

 

[Ferather]

Noted. To be fair I use 99.99% Interactive:X (SPDIF). But I do have headphones, HDMI-DP.

 

[Zonder]

@Ferather . Welcome. The fresh preset has become even better. The sound is clearer - especially the small details of the background. In music, in games-just fly away. But do not forget that the Dts X Ultra is for me like a finishing chord in conjunction with other amplifiers from Alan. I listen with headphones ( professional Beyerdynamic mmx 300 2 gen) and with speakers.
In any case, once again, a huge respect for your work! Keep up the good work.

 

[Ferather]

You are welcome, I will keep the preset available to be used with other drivers. Thank you for the multiple feedback.

@Bryan Ü, try the Surround or 3D modes in Headphones:X v1 (its actually studio sound + headphones:X), you can then use the boost and EQ, so on.
Another option is to use the EQ in the Ultra app, you can mostly likely tune the audio better to suit your setup.
