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

[Bryan Ü]

I dont like Headphones:X v1 its too loud for me.

i sometime hate windows update lol

 

[Ferather]

Yes sorry, the DTS OEM driver has that effect, apparently it can unlock your PC if your manufacturer has a driver for the chip.
Disable Windows auto driver updates, and switch to manual download and install, same for the store.

How to disable automatic driver updates on Windows 10

If you want to use specific drivers, you can configure Windows 10 to prevent drivers delivery through Windows Update, and here's how to do it.

Not long ago the extension would validate with Windows and install a default APO3 and 4....

Yo whats the use of amdacpksl.sys

Driver Reference Table (DRT) | AMDACPKSL.SYS (sysnative.com)

For AMD HAP audio endpoints apparently.

Hello @Ferather I would like to know how to import your preset to Potplayer (Potplayer preset file)

 

[Ferather]

Open Potplayer, go to preferences, then press reset, close PotPlayer, then double click the preset. @Hearick, if you have Z906 or other speakers, plug in headphones and play to SPDIF.
My Z906 will happily take the digital (and analogue) audio in 5.1-7.1 and rematrix it to headphones, using hardware, no apps or additional software.

The headphones out port is on the right side of the volume control unit, top port.

----

@Hearick, found a bug with PotPlayer and analogue devices, the preset will fix this issue, preset updated.



====

@Everyone, feel free to send feedback even in messages, all issues and-or DTS features will be investigated.

Interactive:X, SPDIF:



Reminder: You will need a stereo upmixer to get 5.1+ from stereo.

 

[Gil80]

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.

I'm still not clear what does this driver policy is doing and if I need it.

 

[Ferather]

You don't actually need one, the policy is built into the chip, it just loads and uses that, the file just allows you to change the settings as the file is loaded instead.
For example, the provided settings should unlock HD recording, the EQ and a few other DTS features in the Realtek panel.

It's best you make your own file, using your chip's policy, add the changes, then keep it.



====

With the updated PotPlayer preset, SPDIF (Interactive:X), and E-APO upmixing, play the following: Monstercat - MP3 Lossy, with noise [Stereo].7z
The only thing I was not able to find in DTS SRS was recorded pop noise removal, else you will hear defined channels.

Thankfully all distortion has been removed from the MP3's in playback, auto remastered.

I did 50% volume in Potplayer, and 3 full lights on Z906.

bro im getting some kind of dependency conflict or error in . net native 2.2 while installing dts appx via powershell

 

[Ferather]

Install the all dependencies from the folder then try again, I just double click them.

====

Reminder: Once you install DTS DCH 6.0.9155.2, further updates are optional, not essential, not required.

Enjoy your ALC Pro.

Optional Atmos and Creative for DTS DCH coming soon courtesy of @Alan Finotty.

 

[Bruhimnoob]

bro i dont have microsoft store some windows update corrupted it and i always install from powershell ,it issgiving dependency error any way to install the dependencied by exe files instead of appx.

 

[Ferather]

I see, sorry to hear that, have you tried (cmd as admin): sfc /scannow | Restore Microsoft Store application in Windows 10 - Super User

Note: Right clicking 7-zip File Manager, and running as admin, gives you special permissions to explore and delete.

Good luck.

dts unbound 2019 is installed and working but dts sound unbound 2020 is giving dependency error and any way i can run both dts apo3 and apo4 service in alan finotty's mod??

 

[Ferather]

You will need to ask Alan that, as far as I know, you will get the same issue. He is using the same 2020 app.

 

[Zonder]

dts unbound 2019 is installed and working but dts sound unbound 2020 is giving dependency error and any way i can run both dts apo3 and apo4 service in alan finotty's mod??

Dts apo3 is removed in Alan's mod because it causes a conflict with Sound Blaster. Works in dts ultra only apo4 in spatial mode.

 

[Ferather]

I am actually working on that, Alan has shared his files, but I adapting them fully for DTS DCH. The end result will be shared with Alan.

 

[Hearick]

How can I know if DTS Interactive is working on HDMI ? @Ferather

 

[Ferather]

I have programmed only the Realtek HDMI (from SPDIF interface), you will need to add the Interactive end effect key to the last point, on third party HDMI-DP (AMD, NVidia, so on).
As far as I know, HDMI and high speed Toslink can already carry lossless audio without compression (DTS and Dolby use compression to reduce bit rate).

 

[Bryan Ü]

@Ferather I would suggest to keep the appx file separated not in one 7z file cause if anyone appx gets updated whole 7z file have to be rebuilt and 7z file is huge.

Keeping the appx as it is will allow the users to check the version as well as the one appx will be smaller than compressed 7z file

By the way am hyped for Dolby atmos.

 

[Ferather]

Noted.

----

Edit: I am successful with a new package (still working on Dolby), the new package name is 'UAD DTS'. Its the same as before except the DTS branding, and DTS:X being optional.
I am writing it so that you can choose a naked Realtek version, the installer will ask you if you want to install the DTS pack and-or Dolby Pack (can be added later).




Same result as Alan, with the conflict and Creative, so no Creative at this time.

Hi @Ferather, my laptop is HP 840 G2 (ALC280), I can't use my earphone after I install your driver, DTS:X worked, Realtek Audio Console crashed, can you help me?

 

[Stone-D]

Thank you so much for this, Ferather!

I have a Realtek ALC1220P (MSI MAG B550 Tomahawk, board revision 2.2 - previous versions used the ALC1200 codec), output to Logitech Z906 with both analogue and digital.

After a week of lurking (first I caught up with 100 or so pages of Alan's thread, then the 17 pages here) I pulled the trigger and installed your latest pack, 6.0.9155.2.

It seems to be working.

First of all, a report:
A) With my ALC1220P codec, install option [2] does NOT work but the Main [M] option does. I did not try option [1].
B) Your initial post had this screenshot:

I do not have this DTS tab on either speaker:

Is this an issue? Note that I have not installed any of the presets yet.


Now a couple of questions from a super newbie in the world of DTS:

1) Spatial should be OFF for both speakers, correct?
2) What are the presets for? What do they do? Are they better versions of existing ones? Do I install both Ultra and Ferather packs? Do they apply to both Analogue and Digital, or Stereo only, or what? How will I know they are working?

 

[Ferather]

@giacuong2345, I will try, not sure at this time what can be the issue other than OEM settings you need that aren't in the driver, Laptops can be different.


@Stone-D

The picture from post one was meant to be removed, sorry about that, that feature was not working for everyone.

1: Yes, if off, then off for all speakers.
2: They are only if you want to change the one it comes with, and for sharing with other driver authors.

====

I will be continuing DTS DCH for some time, at a later date, I may bring out the UAD DCH, with Dolby.
Alan has shared Atmos for Gaming, whereas I was looking for more apps and code.

 

[Stone-D]

Ok thanks. I had a look in the Ultra pack and they seem to be device-specific and contained files that would be replaced by the Ferather pack anyway, so I skipped it.

Do these custom presents have any effect in multi channel mode?

 

[Ferather]

Yes, although it can depend on the preset.
