Added shutdown-restart safeguard. Set the .bat file wait time to 6 seconds, adjust to suit.

Re-uploaded: DTS DCH 6.0.9282.1 (Signed), changes:

  • HDMI-SPDIF no longer requires a form factor in order to use APO4 with Interactive or multichannel.
  • Fixed an issue where in some cases the service would stop when pressing off in stereo.
  • Fixed several crash points when no form factor is detected, or not supported.
--

In some cases if you press the off button in stereo mode, you might need to minimise then restore the app to refresh it.

Here is the speaker placement for DTS Interactive 5.1, with virtual side (you can also do this to Speakers):

If you need to adjust PCM (not bitstream, passthrough), you can use E-APO on SFX.

Have you tried to store version recently? If not, I will look into it, however I don't really want to steal DTS's profits, that's totally unfair.
You can't buy Ultra, its not possible, its exclusive to certain devices, the project was to unlock Ultra mostly.

A Full Sound Unbound license cost me about £16, on 10 devices, £1.60 a device (PC).

====

Why DTS don't retail DTS:X Ultra is unknown to me, and the combination of Interactive and APO4 on digital devices is outstanding.
Analogue is dead to me, and many of us use SPDIF-HDMI, so the form factor bit is rather annoying overall.

However, the main concern is audio quality, and if DTS make no profits, we get nothing.

----

If APO4 supported the form factors 8 and 9, Ultra could come bundled with GPU's, and also natively support SPDIF on Realtek.
With the Realtek APO, DTS APO4, DTS Interactive and E-APO, on multichannel I get what feels like 0ms delay.

If you want to edit the preset, copy the .xml file from C:\Windows\System32\DTS\PC\APO4x, edit it, then replace the previous one (original in the package).
Ideally you should use the Ultra EQ (top right, next to settings) to make several personal versions of each mode, or use Custom.

If you want to tune-enable a few things other than the EQ, and Custom, you will need to edit the .xml file.
You should find the .xml easy to read, although you will need to translate things like I3DA.

You will need to restart the audio service, endpoint service and DTS service.

Please note, audio quality (even with Interactive) will vary with the quality of the audio hardware.

Good quality audio device > HDMI-SPDIF-Analogue > Good quality audio out.
Bad quality audio device > HDMI-SPDIF-Analogue > Bad quality audio out.

This is also the same for a bad quality audio file, for example a bad quality mp3 or aac file.

DTS DCH 6.0.9285.1 (Signed) - See post 1 for the download links and guide. Updated the driver infs (will do more another time).
  • Moved the Realtek panel unlock to optional, see the included txt file (may change later).
  • Some polish and changes to improve stereo and delay.
----

If you get any delay or issues with stereo, due to past installs or other reasons (for me, Microsoft driver), rebuild endpoints:

Restart the computer once the rebuild is finished, and FX closed.

You may need to delete old devices, using FX > properties.

If you want extra DTS unlocks, and even 24bit recording, or DTS Interactive does not show on SPDIF, here is a pre-built policy, else, here is a quick video for making your own (with edits).
Normally if there is no policy file on the system (RTKHDAUD.dat), the text will start as green, after get policy, add your edits, then save and exit.

Copy location: 'C:\Windows\System32\drivers\', note, the policy file will remain if the driver is removed.

If you are doing the optional Realtek app unlock, register then restart, else just restart.

----

Note: I am pausing updates, until the two bugs I have noticed with the Ultra app in stereo are fixed, else there is little point.

Tested on 21H2, fresh install, I only got the endpoint issue, due to not uninstalling the Microsoft device first.
Note, even with all APO's removed, you will get delay and other issues if you don't uninstall.

----

APO setups, note the Realtek APO changes based on the device, policy and driver.

SFX: DTS - Idle (preset) | Realtek - Upmixing (varies). < I suggest E-APO for upmixing, gain and balance.
MFX: DTS - Almost everything (preset) | Realtek - Almost everything (varies).
EFX: DTS - Crossover and gain [multichannel], Idle [stereo] (preset) | Realtek - Encoding, other (varies).

SPDIF-HDMI with DTS Interactive (edit for above):

EFX: DTS - Crossover and gain (preset) | DTS Interactive - Encoding.

If you are using Stereo Mix with Interactive, and get a power pop from it after a shutdown (not restart), you can set E-APO to -80 dB:

----

As a side note currently I am back on Realtek SPDIF, the new version slightly beats my AMD GPU audio device (HDMI).
Bonuses: No video feed wasting GPU, SPDIF is much more stable than HDMI (with EDID override).

Note: After a fresh driver install, I usually need to turn off the PC for a few ours before the audio settles.

If your Realtek SPDIF supports 192k, you will be happy to know its utilizing TOSLink 2.0, 125mbps max, and the only change possible is the 2 channel PCM digital converter chip.
Consumer level SPDIF has a 'don't care' to 15 channel ability (44-192k), professional level SPDIF can be set with any number of channels, any sample rate.

You will also be happy to know, if 192k is supported on the Realtek SPDIF, it will also bitstream up to the rate of its TOSLink 2.0 module.
To bitstream any format using SPDIF, set the media player to WASAPI exclusive. Supported formats is technically an EDID.

1642394612446.png

Note: The receiver must also support the format on SPDIF.

Bitstreaming, aka passthrough, passes through.

====

In order to bitstream, the device must have a frame size of 768, both SPDIF and HDMI are using this frame size.
Interestingly, frame size is based on aggregates (8 x 96k), but does not reflect the devices total.

HDMI 2.0+ utilizes a total sample aggregate of 1,536 (8 x 192k), up from 768 (1.4-).
Note: Bitstreaming is not PCM, PCM settings do not apply.

If we was to use the full rate of TOSLink 2.0, SPDIF can do 27 (26.1) x 192k (124.4mbps).

If you are not using the Realtek panel (UWP app), you can safely disable the Realtek Task.
Keep the main service on, it controls the Realtek APO, and improves audio.

----

Forgot to mention, if you want to edit the preset.xml, stop the DTS service and the Realtek service(s), first.
Location: C:\Windows\System32\DTS\PC\APO4x, cut the file, then paste it on your desktop.

I like SFX as "Any" "Stereo", but with some devices-oem setups, you might get a small delay with stereo.

You can use the 'replace all' feature of the editor, once you select a line to change.
Restart once you have pasted the file back to its correct location.

3. install halo upmix,u will find dlls in C:\Program Files\Steinberg\VSTPlugins\NuGen Audio ......now add 32bit version of halo upmix.

Post 1 updated, if you are using a USB device, you may or may not need to convert to HDAUDIO.
I don't own a 'USB\' device myself and cannot test, it may also vary with the device.

Please note the driver does not support USB, the guide is an extension to the installed driver.

----

If you need a modifiable version (add your device) see here, intended use:

To install essentially this package, minus the Realtek, on a PC with no Realtek (hopefully HDAUDIO).
To install DTS and its features on a different Realtek driver, possibly due to OEM setup.

Hello Ferather, a side question about DTS - is it possible to purchase their license outside of MS Store as I'm on an LTSC branch of Windows hence no Store at all?
I mean, is it possible to order some key/license file and place it to the appropriate folder so that DTS detects and utilizes it?
Thanks!

Good question, I know Sound Unbound accepts codes, but they are probably for OEM testers. A while ago I had an issue with the store not allowing purchases.
I contacted DTS in regards to an alternative method of purchasing a license, but did not get a direct answer, just to try some fixes they had.

There is a license file (Ultra +), but you cannot purchase it as you want to (myself too), they come with specific devices.

Thanks Ferather, so at least they exist :) hopefully we'll find a way to buy one - I guess one may buy such a device on Amazon or its likes, even if it's broken as we just need an associated license.
So far I'm staying with your version which is already waaay better than anything I had previously.

I have purchased a full Sound Unbound license myself, after a fresh install a few months ago, and I would absolutely love to buy Ultra, with a good default preset.
You are not the first to say that my version is better, many have tried the original OEM presets and end up not liking it at all, hehe.

There is a bit more than the preset.xml, but regardless I don't charge for my time, I would rather see DTS get paid.
In case you are wondering, this pack is actually for myself, I am just sharing it with everyone.
