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

[Ferather]

You must have a nice and clean install (average 57%), most laptops are self nerfing. Not bad, 99th percentile. You will also be surprised how many drivers some people are missing.
Thankfully, I have all the AMD drivers I need in extracted form (.inf, so on), so in device manager, I go through devices, and search updates on my drive.

With this you can skip the analog noise. 3.5mm in - 3.5mm out.

I used to have a creative USB DAC. That was about 10+ years ago, I decided against it, because USB used more CPU than discrete, might be different now.
If you open task manager, and try and get and idle-stable CPU %, then move your mouse around at a fast rate, watch the CPU go up.

 

[emanresu]

No shit audio and video IS connected, thereby this analog jittery. But watch that task manager drop from 70% to 10% when you open it.

I ran benchmark twice cause my cpu max speed is controlled automatically.I will do clean install again when windows 11 22h2 comes out.

 

[Ferather]

@emanresu, it also depends what you are using the PC for, for example if its a dedicated media setup, with good CPU, it wont matter to you.

 

[emanresu]

So how do we cräck DTS Sound Unbound?
And 2 instances?
We have another part of the forum for CPU flexXxing.

So 32" is too big for my viewing distance, which is about 62cm (~2 foot), I would need more pixels at the distance *, and the curve is too curved, both mostly resolved at around 183cm (6 foot).
It seems I should not go bigger than 28", so I will probably stick to my 24" for the time being (still has a high spec, 1ms, so on), although it only does 75hz max.

Anyhow the DTS DCH driver is working perfectly on my ALC S1220-A, just install and go (I chose main, Interactive on optical).


* If you get closer to your monitor or even TV, the image quality will reduce on larger displays, further away produces a better image.




With Equalizer APO (SFX), upmixing stereo to 6-8 channel audio.

It just doesn't work on my system . installation runs fine and apps install right. Controls are enabled and so but it just doesn't make a difference. Should I disable driver signature enforcement or it won't make a difference with this version of the mod? Windows 11 latest insider build +h610m h. ALC892

 

[Ferather]

Is that analogue or digital? do you mean the DTS app or DTS Interactive? Can you take screenshots?

Yeah sorry. It is analog. Headphones. UWP apps install right and they actually works meaning all buttons and switch are enabled but have no effect on sound.
I can take screenshot of whatever you indicate me.
I will try later disabled Driver Signature Enforcement. I did not before because I was running insecure software ( games) . What takes my curiosity is that all sound seems to be managed or gone through Intel's drivers ? I'm attaching a picture of driver store, so you can check Also , the .csv export of driver list in case you have Driver Store Explorer 'round there.
UEFI audio related options only mention Enable or Disable onboard audio and maybe front panel disable or so.

[Ferather]

I see a few residual Realtek drivers, otherwise you will need to change the APO file to the older one, but I think its the residual Realtek APO and other Realtek drivers I see in the screenshot.

In 'device manager', right click the 'Realtek/DTS DCH' audio device, uninstall, when it disappears, open 'driver store explorer', and remove all 'Realtek' drivers from all sections.
Next open 'FX Config' (DTS DCH driver folder\Tools) and on the right select 'Rebuild All Audio Endpoints', once its has finished, restart the PC.



No Realtek files, only DTS, the Realtek stuff is included with DTS.

 

[Lucky8]

Alright. Followed your instructions and recorded.

How it was before ( as you saw in previous post)

After doing everything and restarting

And I will add the latest state of device manager

So it seems to be working - through DTS driver, but any of the effect or references are present on Windows sound applet, no UWP app ( this time they didn't install but I'm heading to your mediafire's appxs folder to download them.


Update: Headphone X and Ultra working as spatial sound options. Trying to get Ultra UWP to work now

@Lucky8, Good good, if Ultra does not work let me know, you might need the older APO files.

----

If own Sound Unbound, you can download both apps from the store, else only Ultra.

DTS DCH

Watch "DTS DCH" on Streamable.

streamable.com

If you are installing inf's manually, see the 'APPS' folder in the DTS folder.

Thanks you. I must add that driver only worked once I disabled DSEnforcement.

No, ultra didn't work and I'm a bit confused but you should be right about apo but ¿should I use an older driver package? It's Windows 11 and I guess that's part of the limitations all packages face. Also tried Alan's and Puresoft's bundles so far no luck. Trying disabling extra security layers now (Intel's one ) to check once again.

Edit: That's it. DSE must be out then re enabled. It seems any certificate used is invalidated by W11 and each driver may require individual acceptance. One time effort so no big deal.

Big thank you for your help.

 

[Ferather]

The installer (double click) will install the certificate you need, then you don't need to disable driver signing enforcement. If you manually install the .inf files, you wont install the required certificate.

Good to know you have it working, the older files are here if needed, disable windows audio service and endpoint builder, then replace the files.
You might also need to stop the DTS APO service, location: 'C:\Windows\System32\DTS\PC\APO4x', restart once replaced.

There might be an issue with Windows if the certificate does not install for some reason.

 

[Lucky8]

Thank you man.

I got a couple warnings of unsigned certificates once disable driver signature enforcement and trying to install everything. I'm not sure if I will call this an issue with Windows but I believe Windows actually blocks the cert install. I will check cert later. Also, please keep present I'm on an Insider preview build, soon updating to a new flight . There we'll have a clean environment to test

 

[Ferather]

Fair enough, and thank you. I have tested Win11 on my newer setup and on my old, both where working. Windows not working with installing cert's is rare but not unheard of.
In the past I have done fresh installs of Windows, and there be something wrong almost strait away or after an update, unfortunately it does happen.

 

[Lucky8]

Yeah. Usually I update often with clean installs of every new flight ( no in-place upgrade ) . But it it the first time I use Windows Secure Core. I need to get familiar with the full tech but so far I'm putting the blame on it . I'll have some news these days. it is good to know in case someone else experience the same issue
Thanks again mate

 

[Ferather]

You are very welcome, currently I am using an Asus Prime X570 Pro (latest bios), and have all security features enabled, UEFI only and set to Windows only, no issues installing the certificate.

Anyway regardless, you are very welcome, here to help (and bring you high audio quality).

Are you still trying to crack Dolby Access ?

That's an AMD platform right? May be different Intel side. Anyway I'm not discarding anything so I can be wrong and just not having the full picture.

You certainly did both mate. You did.

Edit: Thought I've posted this but gracefully awaited for me in edit. So ...

I just clean installed Windows. The latest public release. Same security stuff. Yeahp, driver certificate install is blocked by default.
In other news, I've cleaned dust from my DVD writer and seems ... ok, take a look:

That's my mobo's DVD stuff. I'm assuming "600" refers to Intel's 600 series chipset. Like my h610.

And this is the sub-folder content

Could I aim at natively enable DTS? Tried running installer . First time it took its time to install the driver and then a UWP app. Apparently it succeeded ( no errors en event viewer has no record of failed install process) but there is no UWP app present ( btw it is supposed to install Ultra ) and no change on system device name. Tried with HD Audio. Then later after installed Realtek driver ( from DVD too ) . That second time, seems to have failed. Driver install console open and UWP install kinda console open but closes immediately ( or maybe it just find record of already installed this stuff)

So, before attempting at screwing up, I wonder if there is a way to correctly install this using the given files and more important, monitoring the install process .

Maybe I should start a new thread also, and avoid hijacking this

What happens if you double click 'signed.pfx' in the /BIN folder (hidden).
