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

Bit of trial and error, some chips (and sometimes Windows) have bugs, I suggest main first, check SPDIF playback in sound unbound, if it plays you're good to go.
Else your chip (or Windows) does not like the settings, you should then use the alternative, it will make SPDIF more generic, but should work.
Okay thanks. I selected Main, but following the instructions in POST 1, I didn't get prompted to restart Windows

"Double click install, wait for Windows to tell you to restart, wait 5-10 seconds then restart."

So I waited about a minute then restarted, should I have waited longer? It said click any key to continue .... Then it closed the command prompt


After restarting I couldn't find this path. 'WIN10\APPS\UWP_Store\' to install the two .inf files.

"Inside the folder 'WIN10\APPS\UWP_Store\' you will find two .inf files, install them.
They are required to install the relevant app, example Ultra."

I did go to DTS DCH 6.0.9172.1\APPS and installed dtsapo4xultrahsa.inf ... Let me know if that was the right step.

Then I went and installed DTSInc.DTSXUltra_1.10.1.0_nuetral.......AppxBundle

But I feel like I might be missing something. My PC is still offline. When can I safely bring it back online?

DTS DCH 6.0.9172.1 (Signed, Rebuilt)

Added an alternative inf, for ALC's that don't work well with programmed SPDIF and HDMI interface associations (some chips have bugs, and-or issues).
Enabled mode specific preset equalizers, changing modes with ultra is more noticeable, updated the configuration properties.

If you prefer another driver version, the Ferather preset, DTS presets and updater can be found here.

----

Here is a much cleaner way to install-update the drivers, right click uninstall in 'device manager', tick 'delete driver', pnputil to remove the extension (see post 1).
In 'device manager' again, in 'system devices' disable 'High Definition Audio Controller', I have two and its the first one, restart, install, enable.

So here is the summary version of the pop we all get with abrupt stop or starts of audio.

Audio [with pop] --> Audio rendering device --> Speakers [with pop].

What we need is for Windows to manage audio better before it reaches the device.
Alternatively, an SFX, MFX or EFX that specifically addresses the pop.

====

I have attached a bonus list of SSTPPCfg, as seen in 6.0.9172.1 (if you are interested).
If you have any issues with speakers or headphones, please post.

The ';;8' comment is an edit, it suppresses pop in some cases.

This file what use? In a Inf file?
 
Yes, that's for other driver writers and-or modders. Tomorrow if you like we can do Teamviewer and I will unlock DTS:X with your mobo driver.
 
No worries, I can unlock DTS:X on Windows drivers, and probably other devices such as Creative or Conexant. Using the DTS DCH.zip I provided and edits etc.
 
What options in my uefi? Mo Bo asrock h310cm-dvs for DTS and other APO? I using modded and unlocked UEFI
 
Thats fine, just download but dont install TeamViewer (can be used without installing), and make a restore point (or partition backup if preferred).
 
Well I updated the pack I posted, I will look into an inf file, however if you know what to do the pack I made above will work.

Ok so here are the instructions in the easiest form, double click 'install', job done, now in /TOOLS, you will find two .reg files.
You need to modify the {Device-ID} bit, here is a video to help, then restore the registry entries.

Using FX, you will most likely need to move the SFX, MFX, EFX, keys to composite.

For non-Realtek, you will need to edit the preset.inf:

[AzaliaManufacturerID.NTamd64]
%Device.ExtensionDesc% = IntcAzAudModel,INTELAUDIO\FUNC_01&VEN_10EC
%Device.ExtensionDesc% = IntcAzAudModel,HDAUDIO\FUNC_01&VEN_10EC

Then disable driver signing.

So keen, alright, I will make you a special inf next update.
 
I can confirm the DTS DCH Ultra pack works on MS drivers (no EFX, not supported), With my GPU I was able to copy the processing mode key into EFX and it works.
Also working on X-FI, it uses LFX-GFX, so you need to move the SFX to LFX, MFX to GFX, EFX is unchanged.

ill give new driver a try this weekend see if it fixes anything
 
I have a friend with an 892 that cant use the latest Realtek drivers, but can with MS drivers, or older Realtek ones, so you might have the same issue.
If you do, you will need to stick to versions that work, where updates may or may not work for your ALC.
 
i dont use realtek but instead using hdmi via nvidia hdaudio. i am unable to install dts ultra as per instructions on the main page. is there a way to install only the hdmi as i am connected via earc and i cant get it to work

You need to install the Apps .inf file located in /APPS/

My ALC889, Z906 (5.1 speakers) and Interactive:X (5.1 encoder) - [SPDIF - Toslink]:

[ALC889, Z906] - PCM, 192Khz, 32bit (not float), 8 channels, +50mbps - Sent - Received - Not processed by my Z906, essentially turns off, confused.
[ALC889, Z906] - PCM, 192Khz, 32bit (not float), 6 channels, +36mbps - Sent - Received - Z906 only processes 2 channels, stereo mode enables.

[Interactive:X] - PCM, 192Khz, 32bit (float), 8 channels, +50mbps - Sent - Received - Not processed properly, noisy.
[Interactive:X] - PCM, 192Khz, 32bit (float), 6 channels, +36mbps - Sent - Received - Fully processed.

the 1st step i install the main dts dch drivers which is for realtek, after that i did the installation of dtsx ultra app(sucessfully). upon completion i did the registry edit for hdmi and restart. upon restart my nvidia hdaudio still detects dolby atmos for home theater. there is no dtsx for selection. not sure why but doesnt seems to work for me
 
Use the HDMI-DP files on your Intel SST, follow this video but with Intel SST. Check it uses EFX, remove EFX line if not. Make a restore point.

 
Yes, just disable store updates, the app will self license, the updates wont:

You will also need to use the HDMI-DP files, and guide.
 
The one above (MediaFire), 'DTS Settings', make a restore point first. Once done, in the the driver install folder is /TOOLS/ with FX config.
My GPU can use EFX, some may not, some cards may also be using LFX-GFX and not SFX-MFX (swap).

Restart the computer, then switch audio device to speakers or headphones, then HDMI for Ultra.
The multichannel version will enable freely without the switch trick.

Edit: See the posts above for more info.
