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

Quick update link now here (some corrections). I did some MediaFire organization, and have moved it to a folder.

hey buddy im still on 6.0.9200.1 with windows 11 everything is working great i use interactive x though spidif 2.0 are there any improvments with the latest driver version to interactive that should make me want to update to latest version

 

[Ferather]

Not exactly, however any changes to APO4 effect Interactive. I recently switched back to Realtek SPDIF, and for me the current is perfect.
To compare it to 6.0.9200.1, I honestly cannot say, during that period I was using AMD HDMI as my main audio out.

Edit: The current package should be more responsive than 6.0.9200.1, as long as you reg clean after uninstall, I suggest CCleaner.

Why did you decide to return to the SPDIF interface?

 

[Ferather]

Currently I have Z906, which only supports 2 channel PCM, DTS Surround, Dolby Digital Live!, this has nothing to do with SPDIF hardware limits.
Directly, there is no upgrade, and my Realtek SPDIF can send all encoded formats (even ones Z906 doesn't support).

I only gain multichannel PCM, and only because OEM's are still catching up to SPDIF's full potential.

----

HDMI audio is 37mbps max, SPDIF + TOSLink 2.0 is 125mbps max, optical is more responsive than conductive circuit, and immune to EMI RFI.
Even the distance TOSLink does 125mbps is futher than HDMI can do 37mbps, There is also optical SMI @ 250mbps.

For audio only, the video feed the GPU has to make is wasted overhead, no advantages to HDMI.

In terms of Windows, neither SPDIF nor HDMI are properly supported, and the EDID is unused mostly.

----

As a side note, now that OEM's now how to implement the hardware for HDMI to do it's max 8 x 192k (1,536k), 37mbps.
They can put the same PCM hardware on SPDIF, it can even be done via HDMI + TOSLink 2.0, no SPDIF.

I suggest SPDIF, because at the lowest level (consumer), it supports 15 channels.

I can send my Z906 6 channel PCM via HDMI to TOSLink, it plays the 2 channels it was programmed to just fine.

----

Now in terms of Windows, my ALC supports quite a few different samples on SPDIF (not the full range though).
Windows fails to show various sample rates, and does not even have a playback test file for 192k.

Windows also has no way to configure the final number of channels on SPDIF.

The G in image 1 is a typo. Here is a slightly older spec JIS F05 cable.

====

@ajf64, I updated, changed the .inf files in the latest package, reducing file registrations and improving total response.
The current package has only 1 DTS bug (bass boost) for stereo, none for multichannel and Interactive.

On some devices you might get a power pop with 'Stereo Mix' after a shutdown, even when muted and volume 0.
I am using E-APO to upmix stereo, I also set 'Stereo Mix' to -80 dB, fixing the pop. This is driver related.

 

[Ferather]

Added SPDIF formats to the main folder. Enjoy! If you are using Win10, 'DTS:X Home Theatre' might not show.
Once you select the formats, you might need to repeat the disable-enable to refresh (EDID sort of).

If you intend to use a different format to Interactive, such as Atmos, you might need to set SPDIF to stereo.
You can use the provided 'DTS Settings' to change SPDIF to standard 2 channel PCM.

hi everyone but can someone please help me to install this

 

[Ferather]

@ClydeZa, The driver or the SPDIF formats? If the driver all you need is in post one, else if you still need help message me a good time to use TeamViewer, or post here.

----

Note to new users:

When using Interactive or multichannel mode, DTS:X Ultra will display its in multichannel mode, the buttons cannot be used, it's automatically configured to channel based processing.
When using stereo, 2 channel mode, this message will disappear and the stereo modes will become active, and usable. Sound Unbound also applies in stereo cases.

The Ultra and Headphones:X are spatial modes for stereo output, stereo headphones and stereo speakers, multichannel, again, is auto configured.

> Also note, you double click 'Install' rather than right click, following the guide in post 1.

Hmmm This Audio Driver want to say something but its huge 1GB. so i did not try.

 

[Ferather]

Same version as current, 1.10.1.0, still waiting for a new version, however its low urgency, only TBHDX to fix.

====

Something to note:

If I plug my 3.5mm jack headphones into the front port of my computer, not so great audio, from the back its ok, from the monitor terrible (DisplayPort, the monitor to blame).
Comparing 6 channel analogue (supposedly lossless) and 6 channel digital (DTS, lossy), from my ALC 889, analogue is -4 db, and a lower quality overall.

If I plug my headphones into my Logitech Z906, which uses TOSLink and with my ALC 889 using DTS Interactive, it sounds great.
My Z906 will also downmix multichannel to stereo, both from analogue and digital, even encoded audio.

Comparing my GPU (HDMI-Extractor-TOSLink) and ALC (SPDIF-TOSLink), they are very similar, but the ALC is preferred for a more direct signal.

Hola a todos, he seguido los pasos del primer mensaje pero no consigo que funcione, no se hablar ingles y uso el traductor de Google asi que supongo que algo hice mal ¿podrian ayudarme?.

Un saludo.

Hello everyone, I have followed the steps of the first message but I can't get it to work, I don't know how to speak English and I use Google's translator so I guess I did something wrong, could you help me?

Deshabilite las actualizaciones de la tienda de Windows, luego desinstale la aplicación Sound Unbound la actualización instalada. Luego instala el que tiene licencia, el del post 1 de este hilo.
También verifique que 'DTS APO4' se esté ejecutando, usando el administrador de tareas. Pregunta si necesitas más ayuda.

Si no hay 'DTS APO4', entonces un software VPN está causando un problema o el dispositivo tiene más controladores de los que debería, y hay un problema en cuanto al controlador.

Lo hice y no funciona.

No aparece en el administrador de tareas.

Entonces ese es el problema, ¿el dispositivo de audio se muestra como 'DTS DCH', como en la imagen de arriba? Si es así, revise 'pnputil' usando el símbolo del sistema, como en la publicación 1, para ver si tiene otros controladores que causan problemas.

Tambien hice todo eso, y paso a paso quite todos los de Realtek antes de instalar el nuevo.

¿Tiene tiempo para usar TeamViewer, entonces puedo ver. Envíame un mensaje al usuario y pasa.

 

[jose_luis]

Por supuesto, lo abro ahora mismo!!!!!

¿Por privado?

Creo que todo fue bien, no noto nada mal por ahora, y espero que sea asi .

Muchas gracias por la ayuda, sin usted no lo habria conseguido , mil gracias por ayudarme .

Y peor es si la guía se trata de parchear programas usando desambladores, debug y lector de código máquina ya que te muestran un programa que también en ingles avanzado xd
