Features: DTS:X Ultra (APO4), DTS Headphones:X v2 (Sound Unbound), DTS Interactive:X (APO4).

Apps: https://www.mediafire.com/folder/tk7ola8b5j6xt/DTS_UWP_Appx

----

First, uninstall all previous Realtek drivers, including any past installs. Use pnputil (see here), to scan the system for residual drivers and extensions.
The quick way to use pnputil is two commands, "pnputil -e" and "pnputil -d oemX.inf", the X represents the number you see on screen.

You can check the 'provider', 'class' and 'signer' to identify any drivers that should be removed.

----

To install-update the drivers, right click uninstall the device in 'device manager', tick 'delete driver', pnputil to remove the extension (see above).
In 'device manager' again, in 'system devices' disable 'High Definition Audio', I have two and its the first one, restart*, install, enable.

* Make sure you run CCleaner registry cleaner a few times, and remove any apps before restarting.


----

See '\TOOLS\' for extra steps to unlock more features, settings, via the Realtek policy editor (RTK Device Tool.txt).
Enable 'Stereo Mix', mute the stream, then set it to play to the device, to keep the encoder always on.

Note: The Realtek Neo-PC option can cause noise in some cases, use only if needed.

----

To use the provided Sound Unbound package (which contains a license), disable Windows store auto-updates.
You will also need to uninstall any updated version, before re-installing the provided one.


----

How to setup USB-HDMI (non-Realtek devices) here, for HDAUDIO devices, you need only need 'DTS Settings'.

----

Known issues: Some digital output devices are not detected properly with Ultra when in stereo output mode.
Workaround: Switch to speakers-headphones then back each startup (or use VB cable, other).

Some VPN's software may block the APO4 service, and need configuring.

@popm, you have a conflict as mentioned, most likely a VPN, some VPN's or security software can block the license checks. Why is the inf edited?
@tuanh2202, try the following command via admin command prompt, then restart:

regsvr32 "C:\Windows\System32\DTS\PC\APO4x\dtsint64.dll"

Does DTS:X Ultra only work on the device named "Speakers"? Whenever I try to use it with the SPDIF device I get the same problem as that previous user. The app comes up but I cant change anything. It also dosent work on "Speakers" if I have the output set to anything other than stereo. Is it meant only for stereo audio? If im using SPDIF output and have DTS Interactive enabled for default format do I even need to use the apps for anything?

@drnick88101, if you see the image below, Ultra is in multichannel mode and auto-configured, there are no buttons (they are for stereo).
The same for the spatial modes, they are also for stereo speakers and stereo headphones, not multichannel (which is auto).

DTS Interactive is 6 channel (8 with virtual side), the same for any speaker setting above 2 channels.
I am using Equalizer APO to upmix stereo audio to multichannel (8 channel) audio.

Ok thank you for the reply. I was just doubting it was doing anything because the on/off button dosent work either so i wasnt sure it was doing anything. Sent you an optional question about the stereo upmix, too. Ive learned alot from your posts, thanks for all you do!

I just downloaded that stereo upmixer along with this driver and it sounds so good! I had so much trouble setting it up though because after checking out other threads with similar drivers i expected there to be some config involved. Like having to use that realtek thing or policy editor or that fx program and i didnt know what options to use for them. After alot of uninstalling back and forth it turns out i didnt have to do anything. The driver install did everything (well i guess i did have to install the policy it came with). I wasted alot of hours figuring it out but i learned alot so its ok. thanks for this easy to use package!

I had problems with another modded driver, not working properly and essentially breaking the computer with heavy mods.
Had to re-install Windows to fix the problem produced by the other modded driver, then made my own :p
