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

So, this is for headphones only, right?
I mean this is no good if you use a HT system.
My PC is hooked to my Denon HT system, so it is not going to do a thing.
 
This works with both headphones and HT but most of the time has gone in to HT sound quality so it should work very well with your denon HT system i used to run it with an onyko set up if your having issues you prob made a mistake setting it up.

Never even thought about installing it or any other application for my system.
Not sure that I would hear any "net gain". and if it messes things up, I would be so mad.
Never mess with a good thing.
When you used it with your system did you hear anything different?
There is just not enough information about this stuff on Google. It is like trying to find anyone that has reviewed the KD-51M Speakers.
 
Headphones, speakers, HT (multichannel) and stereo, with added bonus of the same on SPDIF. I pumped a lot of time to make sure the result is perfect as possible.
Will it mess up your audio, no the opposite, unless you are used to other enhancers (Nahimic for example), and have got used to them.

I'm told this is the best driver on SPDIF, due to my added support, and miles better than most official releases.

I use the driver myself, and I don't upload to get gains, simply to share.
 
I do not "Use" any of them Nahimic or the like all my "sound" comes from the HDMI channel.
Can you really make an app that can improve on the sound signal?
 
This version of the driver installs onto a Realtek (onboard) sound device, if you have one, you would install the package, then add the features to your HDMI (Graphics card).
The sound quality will improve, as most of the time HDMI is using the Windows FX system, which you will replace with the DTS FX system.

I have tested the changes on HDMI, and yes the audio quality improves (compared to Windows FX).

----

Download: DTS Settings (edit link updated).

Files: 'DTS Preset.reg', 'Multichannel [Interactive].reg' or 'Multichannel.reg'.

> Open 'FX Config' (Tools folder in the driver package), select the HDMI device from the top, then on the right press 'Copy GUID'.
> Right click and edit both .reg files, replacing {DEVICE-ID} with the one you copied from 'FX Config'.

> In Windows sound settings, right click disable the device, import the .reg files using 'FX config', then re-enable.


>> Use Interactive to get DTS Interactive on HDMI, or Multichannel to get the same but as PCM.

I suggest restarting the computer after you finish the changes.

If your receiver supports DTS:X, and you are using Windows 11, install Sound Unbound and enable HT on HDMI.

Some of those posts are a little old, and will certainly confuse you I apologize, I will adjust your steps to meet the much more simple current version.

1. Disable automatic driver updates -- I personally don't need to, but some hardware will auto-update.
2. Uninstall all current drivers and extensions -- Check 'pnputil' anyway, even with a fresh install.
3. After uninstalling, install my package then restart -- I added service terminate to the installer to make things easier.
4. Enable stereo mix (to avoid popping sound from speakers) -- My S1220A and ALC 889 did not pop *, but some other ALC's might.
5. Updated 'How to get the most from DTS Interactive' here, no preset .xml edit needed.

Not needed:

> Registry cleaning, I updated the driver files a while ago, they will unregister on uninstall, the installer will do the rest on install.
> Realtek policy or policy edits, only if you want extra features to show in the Realtek app (I don't use it myself).
> Applying SPDIF formats, not really required, unless your receiver supports Atmos over SPDIF.
> No DTS apps are needed for multichannel, they are for stereo, no need to install.
> "Do I need Nahimic, Boom3D, Sound Blaster or similar apps?" -- No, and I only use Equalizer APO to upmix stereo to 5.1
> Software dependencies, ignore this unless you have issues running the DTS apps.

Note for the older provided Sound Unbound (comes with license), disable Windows Store auto-updates.

* Start-stop pop.

Thanks for your help :) I did as you wrote, everything is fine :)

In my case the popping sound is terrible, so I have to use the "Stereo mix" trick, but that's not a problem ;)

I'm synthwave music addicted which sounds much better with your driver, so thanks again :)
 
No problem, some devices and receivers will have start-stop popping if you are using Interactive. Unfortunately I cannot fix that other than the stereo mix option.
You can get the same pop if you start-stop audio playback very quickly even with analogue, I don't think Interactive has a buffer.

Some people have said they get delays with some encoded audio, but not with Interactive.

----

If you are using Interactive on both SPDIF and HDMI, you can set 'Stereo Mix' to default playback device, so it works on both.

Honestly the start stop pop should in most cases if you are useing just the driver with dts:x ultra should be super minimal i never really noticed it except in really rare occasions all those add on apps for me only seem to make the sound quality worse just stock interactive:x was always the superior option for me specially when it comes to an HT system with optical only. Tho 90% of my content was multi-channel

need some new cables :) https://www.kitsunehifi.com/product...s-1m-length-50times-higher-than-spdif-signal/
 
I agree, I am using 3 APO's in this case, DTS:X, DTS-Interactive and E-APO (to upmix stereo), and I don't get start-stop pops either.
Possibly it's the way some ALC's are built, and-or the way receivers are built. Either way 'Stereo Mix' fixes that one.

I use stereo mix because I prefer the decode light to stay on, like when I had Creative X-Fi Fatality.

====

If you get any audio oddities after installing E-APO, or any other reason, disable the DTS DCH audio device, then shut down.
Turn off the power at the PSU, or unplug at the wall, wait 5-10 minutes, then boot and enable.

It seems that Windows Audio Engine gets a little confused.

Q: What is the external speaker package for, and do I need it?

The external speaker package is for SPDIF-HDMI and to use stereo modes and features. It's not needed if you are using Interactive/Multichannel and never use stereo.
If you are using analogue, headphones or speakers, you simply install the driver as normal, that's it, no extra steps are needed.

----

DTS Settings - To add DTS/Realtek to any HDAUDIO device that currently does not have DTS/Realtek. To change SPDIF-HDMI between stereo and multichannel.
External Speakers - Bypasses the form factor check built into DTS APO4, essentially adding 'External Speakers' to SPDIF-HDMI, other.

----

If you are using Interactive/Multichannel always, you do not need the DTS apps installed.

====

Officially SPDIF-HDMI within APO4 is not supported, hence the extra steps (optional files). Multichannel is unlocked without form factor.

How to convert a Virtual-USB device to HDAUDIO (and unlock Ultra). In this example, I am using a virtual device.

> Open 'FX Config' and select the device you want, then on the right press the 'Jump to Properties Key', this will open 'Regedit' at the device.
> Find a 'HDAUDIO' device on the system (left side in Regedit), it can be anything that says 'HDAUDIO', I used Realtek.

> Find and copy the value of '{b3f8fa53-0004-438e-9003-51a46e139bfc},2', replace the value (same key) on the virtual device (USB).
> Next, replace the value of '{a45c254e-df1c-4efd-8020-67d146a850e0},24', with 'HDAUDIO', then restart your PC.

does this driver now supports Asus sonic studio 3 enhancer. My mother board is asus rog maximus Viii formula that is a alc 1150 with HDA driver with sonic studio 2. when i tried this driver in then past i never seem to get the same level of bass as i got with the stock (outdated) driver.Also i use analogue 5.1 audio so no HDMI and SPDIF for me
 
dts is much better it gets more level when you move to hdmi but for spidif dts is on codec to rule them all
 
We are at the point where updates are going to very little for audio improvements, almost no point updating the Realtek files other than new features.

I messaged a staff member to update post 1 to a more simpler guide.
 
Hello, I just came to say, thank you very much for helping me with the installation, I'm flying with the new sound!!!, thank you thank you thank you thank you very much !!!<33333333 from Argentina
 
does this work with realtek 4082 usb audio ?
 
No I don't think so, the 4082 will likely be USB interface whereas these drivers are for HDAUDIO, although I could be wrong.
 
Some of you might get Realtek updates from Microsoft updates, see here to disable it. In my case I don't bother as Windows never finds an update.
If you are using third party apps, they might have another source of files and also try to update (replace) the driver.

In these cases it will cause you to lose the current install, and also the DTS apps will stop working.
 
i tried your new driver with EAPO for 5.1 for my analoge system and i had to change my high pass to 80hz to hear the bass. Right now i am using 120 hz for low pass what is recommanded HZ for low pass filter?
 
It varies with the sound system, but around 40-180hz is common. An example spec below:

What is low pass filter I can't hear any difference if I change its value and should high and low value should be same? right now I am using two different value cause as 80hz on high pass brings back the bass for me but on low if I use the value 80hz the bass for is not sharp.so any suggestions?
 
The high pass filter section, removes the set frequency and below from the assigned speakers:

This removes bass from the satellite speakers.



The low pass filter section, removes the set frequency and above from the assigned LFE:

1670353032831.png

This removes all but bass from the LFE.


What is Bass in music and how it affects your music experience?

----

Use channel factor to increase LFE volume, 1.0 = 100%, 1.5 = 150%.
