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

[Bryan Ü]

@drnick88101, with the Realtek driver installed I use 'DTS Settings' and FX Config. Open FX, and select the AMD, then select 'Copy GUID' on the right. Make a backup (also on the right), edit the .reg file and replace both {DEVICE-ID} points with the GUID you copied (paste it). Disable the device via Windows settings, apply the .reg, change the format (see this video). For Interactive, you select Interactive, disable, and repeat restore the .reg.

Its ALC285
Reinstalled the windows with orginal driver.

@Ferather
Hi, I've read all 26 pages in this thread. I learned a lot of information that I didn't need. I'm so confused, so bored and tired of trying. I need help.I admire your efforts.

MSI GS40 notebook
Windows 10 Home 20H2
ALC899
Logitech z906
Boom 3D 1.2.3 works fine on my system. (3D Surround)

I'm not interested in DTS:X, all I care about is that the Realtek equalizer works fully when DTS interactive is on. (My goal is to prevent the sound from being muffled when watching 5.1 movies and playing games..)

After installing DTS DCH 6.0.9205.1, DTS interactive works properly. however, the Realtek equalizer only activates on the front channels.
The equalizer has no effect on the center and rear surround channels. sound is heard unchanged on these channels.
In fact, the problem is even more complex. If I turn on the environment effects in the realtek panel, those effects are heard on all channels... the problem I mentioned only occurs in the Equalizer.

I uninstalled the drivers manually from the device manager in each installation and uninstalled the applications as described in the forum.
I use CCleaner 3 times in a row.
I did the detailed driver removal process with DriverStoreExplorer software. (You said don't use it, but I couldn't understand why.)

note: AAF DCH Optimus Sound 6.0.9205.1 In this package, I could not activate realtek equalizer while dts interactive was running in any configuration.

 

[ajf64]

its more apt to be muffled with equilizer on id turn off effects it really should not be muffled at all if installed right i run with all effects off and its crisp and clean just like normal dts

@Fx7, I have read your post, I will be with you later with a better response.

@Fx7

Thats how Realteks enhacements works.Limited. Better use then EAPO and peace eq.

 

[Ferather]

@Fx7, you are correct, the Realtek app only does stereo on SPDIF, it can also cause a bug, which you don't need to worry about (used to make Ultra go wonky).
So I went ahead and tested all my outputs on ALC 889, with the current release, Headphones, Speakers, SPDIF, I dont hear any muffle, however:

I have two audio devices plugged into my Z906 via SPDIF, My AMD GPU (HDMI > SPDIF), and ALC889 (SPDIF).

Using Potplayer I can play the same music file to two devices at the same time, and on the Z906 simply press a button to compare.
Both devices are programmed with the same APO's (AMD came with no APO's), DTS APO + Realtek APO + Interactive.

So directly comparing the two, equally, the AMD produces about 33% better quality and roughly the same for positioning.
As a bonus, on HDMI with Interactive, DTS-HD MA is decompressed to PCM, then Interactive (with APO4, DTS:X enhancing).

That's with the Sound Unbound app (decoders), the second part of the license, if you own a full one.

Edit: PS, its not really Interactive anymore, Its Interctive:X, yes you do want it, trust me, big upgrade.

----

@Aleksandar012, the Realtek APO is actually pretty good, even with uncontrolled defaults.
ALC devices are the problem, they fail to produce, re-produce good quality PCM.

====

Note: Having an ALC on the system, allows you to use Ultra (even on other devices), I still need it for a mic.

 

[Ferather]

Small change to 'DTS Settings', changed [Interactive] and [Multichannel] format keys slightly, and set a 6 channel point.
The Interactive edit will be present in the next full release, which will likely be when DTS core is updated.

If you use Interactive, you will need to repeat the process after selecting it on a device that has not used it.

hi which driver are recomended for asrock z390 itx, it have build in creative connect, but since i have usb speaker i cannot use it, i managed able to enable dts heaphone / dtsx but on sound cp taskbar (right click) but can only set dts profile when having dts audio enabled which uses 3.5 output,

btw have you tested sony audio driver / ms usb 2.0 audio driver i find Sony Music Center for PC quite good also it have dsee its like updated BBE pls check against wma / foobar, tks

 

[Ferather]

You will need to use the DTS Settings on the USB device, you may or may not need to trigger detection to use the panel.
Once setup it should continually load your settings, and-or chosen preset, let me know if it doesnt.

I forgot to mention, if you are using the alternative install to use stereo on SPDIF.
You will need to enable DTS Interactive for other devices (see below).

Found these online, the source file was probably an MP3 or AAC, so still lossy. I am using Potplayer, so no need to bypass 6 channels in E-APO.

Maintenance

 

[elpolaco_]

Hi people! I have an issue, I have a Sony Muteki 5.2 conected trough SPDIF to my motherboard (ASUS PRIME Z490-P), the cable it's bright new, the issue it's that when I do a fresh startup with my PC and I put music or videos or whatever, the sound beggins to cut randomly, but when I restart the problem goes away! I also have a GTX1080ti conected to 2 monitors (One HDMI and the other DP) and a TV with HDMI, and I have a Soundblaster ZX soundcard that I only use for my headphones, I disabled de NVIDIA HDMI audio and still the problem remains. I have an custom Realtek Audio driver installed for the Muteki (I think it's the 2.80 version) wich allows me to have coded audio trough SPIDF (that's why I connected this cable), trough HDMI with the graphics card couldn't get any encoded audio but I had 5.1 sound.

I don't now what to do, the options I think are:
-Get back to connect all through HDMI and have no encoded audio.
-Found a driver that make the problem solved.

If there's something that you think could solve this I would be SO greatful, I'm an audiophile and this issues gives me headaches . Maybe you guys know any way to get encoded audio trough HDMI or there's any configuration/driver/tip that you might know I am at your knees.

Thank you in advance! Sorry if my english is bad, I'm from Argentina.

 

[Ferather]

Hmmmm, that's a good question. I can offer 2 options, however there may be a chance Windows is buggy if there is an issue, but hopefully its a driver or a Windows update and config issue.

When it comes to Nvidia GPU, feedback with one of my packs, mentioned that the Windows driver allowed them to use all the formats supported by the device.
When it comes to a Realtek device, this driver will do it as long as the device you use it on is not OEM modified, most are not.

You have an ALC 887, the model below mine (ALC 889), and should be ok if not modified.

----

I suggest following the above guide and post 1 for a clean uninstall of all Realtek related drivers, original ones, modded ones, as much as you find with pnputil.
If your Windows is healthy and it was a removable issue (fingers crossed), hopefully it gets removed in the process of updating the driver.

Once you have the driver working, you can add encoded DTS out to HDMI and other devices.

Feel free to ask for support, I also do TeamViewer when I have time.

Main: DTS Interactive (48/24) out for SPDIF-HDMI | Alternative: 2 Channel PCM (48/24) out for SPDIF-HDMI.



----

Note: You will need to disable Windows Store auto updates to use the older self licensing Sound Unbound.
Else it will update and you will lose the license, Ultra can be downloaded from the store.

If you own Sound Unbound, you can download the store version, and set to 'none' for Ultra mode.

thank you

 

[Ferather]

I am still working on an improved service and controller, I have managed to fully unlock multichannel (anything above 2), stereo (2 channel) mode is tricky to work on.
DTS are very good at implementing licenses with their software, although it would be nice to buy Ultra, USB devices will likely not work yet.

Along with the latest maintenance I did, I set DTS APO4 to use automatic mode and external speakers, if detection fails.
In short, if for example a USB stereo device is setup via 'DTS Settings', it will load automatic as default.

This is pretty much the same as multichannel automatic, but as stereo.

Stereo mode on Realtek, and GPU's (HDMI) work, if you use the detection trigger, Realtek analogue (Speaker-Headphones) works by its self, you can control the app.
With the recent changes, and a USB headset, the Ultra app flicks into Headphones mode, which means detection is working.

I have not tried a USB license just yet, however the system should load any license.

I purchased Sound Unbound, and have a full license on up to 10 devices. I download both Ultra and SU from the store.
If you dont have a SU license, you will need to use the older provided one, which contains a license.

You will need to disable store auto-updates, but it will work even on USB.

[envizion]

Does this enable DTS 5.1 live encoding through optical out (receiver doesn't support DTS:X if that matters)? I previously use the optical out with SoundBlaster Z and its 5.1 live encoding feature but its dead. I have a Asus Supremefx S1220A.

 

[zais]

hi thanks & on g560 usb speaker i find custom as these optimal, take care all

 

[Ferather]

@envizion, yes it has DTS Interactive, as long as the receiver supports it. I have it running on Realtek SPDIF, and AMD GPU. Your receiver does not need to support DTS:X.
I have programmed the driver so that the DTS:X enhancers are applying their effects to the audio before it becomes DTS Interactive, hence Interactive:X.

You can use 'Stereo Mix' to keep the encoder on with constant muted stream, or passthrough stereo to other devices such as USB headphones.

If you want to upmix stereo to mulichannel, I suggest E-APO (see here).

====

So I am finished with the service and controller, I have one more maintenance update, changes, but its not urgent and will be in the next driver update.

Stereo mode works on speaker-headphone pin config, read from the driver or registry, SPDIF-HDMI etc don't have pin config.
If the device is 'HDUDIO' pin data can be transferred via speakers-headphone to, for example, SPDIF.

Hi thank you for your answer. @Ferather
I don't want to use hdmi. I was able to run DTS:X ULTRA on SPDIF only in stereo mode.In my experience the sound change in stereo mode is a complete disappointment and It didn't activate in "DTS Interactive" mode. I've watched many methods and videos shown here, but it still doesn't work. I don't have vpn on my system either. dtsX ultra has been mentioned here for pages, probably this software is not working properly for me. I have the license for dts sound unbound software.

[Ferather]

@Fx7, when using DTS Interactive, it should display 'DTS:X is in multichannel mode and is auto configured', none of the stereo buttons-options will be usable.
For me the stereo processing is very good, but I have noticed the app needs to be reset in some cases, I am working on maintenance.

Ok I have finished my maintenance and testing, I am now moving onto stereo presets.

 

[Fx7]

@Ferather Thank you for the explanation.. yes, this text appears on the screen, but there is no change in the sound.I turn off sound enhancements to feel the difference as there is no turn off option. there is no difference in sound. That's why I'm confused. so it makes me feel like this: When DTS interactive is on, DTS:X doesn't seem to make any changes to the sound. (I also have the same experience with the AAF driver.)

How to cleanly install DTS DCH (don't skip steps), turn off your internet - unplug the cable or turn off wifi. DO NOT use third party software to skip steps.

----

First uninstall all Realtek, AAF, DTS or other installations from 'Apps & features'. Then restart your computer (it will probably ask you to restart).

View attachment 193207

Then in 'Device Manager', check for 'Microsoft Audio Device', If it still says 'Realtek' or 'AAF DCH Optimus Sound', you might have an issue.
Right click the device and select 'Uninstall', then tick 'delete driver', and restart your computer, repeat until the above.*

* If you don't see 'Microsoft Audio Device', you need to repeat the process until you do.

View attachment 193208
View attachment 193209

----

Now open 'Command Prompt' as admin (note, you can select screen text, and press ctrl+c to copy, and right mouse to paste):

Type the following command: pnputil -e , this will display all installed drivers, look through the vendor, device and signer list, copy the oemX.inf name.
Now type the following command: pnputil -d oemX.inf , this will delete the driver, however it must not be in use (uninstalled).

If a driver fails to remove, uninstall the 'Microsoft Audio Device', do not restart, and try again (it will now).
Make sure to remove everything related to your Realtek, including past installs.

View attachment 193210
View attachment 193211

Now run a registry cleaner (CCleaner) 2-3 times, and restart.

----

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

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.
