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

[ajf64]

GPU 12 w.

nice so we are about the same whats your cpu package power

 

[Ferather]

So, not as good as yours it seems, or HWMonitor is working differently, 48w mostly idle. CPU has a 360 AIO.



====

If you like the audio after installing the driver (I will fix the bass boost tech bug soon), buy Sound Unbound.
I admit the files are unlocked and have been improved, but are still provided by DTS.

Yes Sound Unbound should-will interact with the driver (last time I checked).

Note the Sound Unbound spatial modes are for stereo (headphones-speakers), not multichannel.

Here are some images after registering RtkApi64U.dll, see 'RTK Panel.txt' in the 'TOOLS' folder.






Some of you may need the extra policy options.

 

[Ferather]

The last image is slightly wrong, the amp shows on both endpoints after separation, independent speaker and headphones amp.
I suggest performance, although I am able to take DTS EQ's to max with extreme and 100% volume.

Make sure you restart after separation (Device Advanced Settings).

Realtek Impedance Sensing - Google Search, will look into it at further date, not finding much, or anything I can do about it.
Hmmm maybe its just me, thinking high ohms is an issue, apparently not, see here and here.

App packages updated, see post 1 for the link.

====

I am not using any policy edits, most of you shouldn't need to, also note my S1220A does not have DTS normally.

 

[Ferather]

I have not tried this, but for you analogue users, you probably can reduce the power amp to minimal, and increase audio in PCM (digital) using E-APO (+20 dB) or similar.
Power based amps suck to be fair (Digital > DAC > Analogue > Power Amp | vs | Digital > Digital Amp > DAC), preferably use PCM.

Reminder analogue is power in a circuit, digital can have no power (example optical).
No such thing as lossless analogue, will never exist.

----

@ Realtek, here is the technology you should be using: PowerDAC V2.1 | index (e1dashz.wixsite.com)
You should also consider adding dB detection, and not amp over a certain level.

----

With SPDIF-Optical at max volume (Windows) and Potplayer at maximum, I was able to do +28 dB using E-APO, although its max supported is +20 dB (software).

Anyone who is looking to disable the CAudioLimiter, I have attached a registry edit and required app to this post, here are the instructions.

Backup the current data (Regedit > edit > find > CAudioLimiter), right click the main key and export.
Use ExecTI to run Regedit, then import the .reg I have provided.

[Ferather]

Just noticed a mistake in the Class ID's.txt in the 'TOOLS' folder, package re-uploaded. No other changes.
I will do an update around 6.0.96XX.1 area, nothing to fix-change at this time.

 

[Ferather]

So far disabling CAudioLimiter has had nothing but a positive return for audio, even with DirectSound and 32-bit float.
I will probably add it to my package into 'TOOLS' at a later date. Even MP3 DAB sounds better.

I disabled all audio endpoints, applied the change, rebooted, then enabled.

50 dB PCM > PowerDAC > 50 dB PWM | 100 dB PCM > PowerDAC > 100 dB PWM



100 dB PCM > PowerDAC > 100 dB PWM > Driver > 100 dB SPL



DMAS for the Win! Also: 20Hz-20KHz(+) = 44.1/48k sample rate.

 

[Ferather]

Here is with the file registered (see tools), the newer Realtek app and DTS Ultra installed, clicking the DTS icon opens the app. Performance (amp) was the default-detected setting.

 

[ajf64]

is that for speakers only or dose it work on spidif for the dts ultra tab in the control panel?

 

[Ferather]

No Realtek have not implemented a shortcut from SPDIF to the Ultra app, you can just open it manually from start. APO4 normally only reads form factors 'Speakers' and 'Headphones'.
If you are using DTS Interactive on SPDIF, DTS APO4 will enter multichannel mode (which you will see in the app), without 'Speakers' or 'Headphones'.

With SPDIF in stereo, APO4 should still be active, but to fully use the app you will need the 'External Speakers' optional pack.

[brotherscro1]

Hey guys just checking after a while whats the latest working method to gets DTS Interactive / Dolby Digital Live working?
Planning on upgrading to Windows 11 so worried my old method is no longer gonna work
I'm currently using dvojinov method and 6.0.1.8059 drivers (only thing what worked ) I need this because of my Logitech Z906 speakers only way I can get 5.1 DTS over optical for games
My motherboard is X99 Sabertooth
Also to get same Realted HD Audio Manager as in screenshot
View attachment 295720

 

[Ferather]

If you want just DTS, this package should work fine with your Realtek ALC1150 (X99 Sabertooth), just make sure you fully follow post 1 to remove all previous drivers (clashing data).
I am using E-APO to do upmixing (no DTS Connect). If you need help installing the DTS DCH driver, message me and I can help you install it.

The DTS DCH pack contains a UAD-DCH driver, so the Realtek app is different (see above). I am using Z906 and Optical for everything, music, movies, games and so on.

====

Easy read version of post 1, with additional instructions for the optional extras (else just install and go). Post here if you have questions or issues.

 

[ajf64]

works the same on windows 11 as it dose on windows 10 for the most part i have never really had any issues with it on windows 11 tho that control app is super old may work in compatibility but not sure how well that will work on 11

 

[Ferather]

It's because the driver that brotherscro1 is installing to unlock features is a HDA version, the newer version is UAD-DCH. The older HDA indeed should still work, there is no enforced changes with Win11.
I would encourage him to update to a suitable UAD driver, in some cases the older HDA version might not support more modern features you have available.

The only thing is getting the exact features that are requested, I can only offer DTS, no Dolby.

 

[Ferather]

Fixed the power off button in the updated preset, I apologize, I forgot about save last used mode.

HDA average execution time is 2us (9/10), 1 out of 10, 48us. HDA, DPC less than 54us (cant see).

Found this interesting: Why your audio is bad and why you can't do anything about it - YouTube

Makes we wonder how many of you got used to THD (and supposed warmth).

====

If you want to disable DTS FX processing without disabling enhancements in Windows, use the power button (Ultra app).
If you want to change the default mode (also used for multichannel) edit the DTS preset (example below).

> Go to 'C:\Windows\System32\DTS\PC\APO4x', and cut/paste the .xml file to your desktop.
> Edit the .xml (notepad), change 'APO4-Operating Mode', save, cut/paste back.



> Open 'Regedit' and go to 'Computer\HKEY_LOCAL_MACHINE\SOFTWARE\DTS\APO'.
> Delete all the endpoints but not the APO key, then restart the computer (x2).



You can do the same if you are making/tuning your own modes.

 

[ajf64]

God bless you sir

 

[Ferather]

Reminder:

To reset all endpoints (Realtek-Windows can be weird), disable all endpoints (recording then playback), restart, wait a few seconds, enable (recording then playback), restart again.
You can also disable the HDA bus and do it that way if you find it more convenient, I'm all out of general tips at this point, xD.

EAPO upmixer updated (see here), downloaded flac test audio here (not perfect but gives you an idea of expected quality).
You should notice specific rear audio even though they are stereo files and don't have rear.

Also note DPC tests where done with optical in HT mode (6 channel), full config, not legacy method.

----

Added 'Win CAudio' to 'Settings and Utility': https://www.mediafire.com/file/4atyjj2310eivvo/Win_CAudio.7z
Disable all endpoints, apply the reg, restart, enable endpoints (as above), enjoy the audio.

 

[Ferather]

Currently I am on a break, but I will do an update around the 6.0.96XX.1 area, new Realtek files are not exactly urgent at this time (for me at least).

----

I am aware of two small blips with DTS APO4 when using custom mode:

• The bass boost option has attenuation and can sometimes act a bit odd when turned on, but not after.
• Switching between wide-front spatial modes can sometimes not refresh instantly, and act odd.

I will look into it at a later date, however custom can still be setup and used, so its not too big a deal.
No issues with Realtek (other than default analogue amp mode) or DTS Interactive.

----



Enjoy!

 

[DreaminquE]

Can I use DTS DCH with your drivers when I connect my speakers to the monitor for digital audio?

 

[Ferather]

Sort of, DTS APO4 natively only supports some form factors for stereo modes (Speakers, Headphones), HDMI and SPDIF are not supported (multichannel only).
You can use the 'DTS Settings' to program a GPU, but to get app stereo control you need the other package or switch devices then back.

Guide here

 

[DreaminquE]

Bir nevi, DTS APO4 doğal olarak yalnızca stereo modlar (Hoparlörler, Kulaklıklar) için bazı form faktörlerini destekler, HDMI ve SPDIF desteklenmez (yalnızca çok kanallı).
Bir GPU'yu programlamak için 'DTS Ayarları'nı kullanabilirsiniz, ancak uygulama stereo kontrolü elde etmek için diğer pakete ihtiyacınız var veya cihazları değiştirdikten sonra geri dönmelisiniz.

I already have a stereo sound system. What driver is required for me?
