The volume on normal using is just good. The problem come when in gaming, when the pc is using spatial audio. The volume turns down a lot when gaming. BTW i didnt find a good solution for my configuration. Im not a pro of Hi-Fi sound, im testing a lot of possibilities, but really cant find the right one for me.

@dongeg97, I would use the DAC in your receiver since you already own a high quality DAC. If Dolby Digital sounds better to you go for it.
Ideally you should output multichannel (5.1-7.1, based on receiver and encoder), and plug the headphones into the receiver.
In my case I am using Logitech Z906, so multichannel PCM and encoded audio is output to headphones (plug).

Hi @Ferather . I have done a fresh Windows 10 installation and since I can't get the same version of your driver that I had installed before, I got the latest one and is working with no issuses, except when I want to change the sound to stereo with your DTS settings (you shared me a couple of registry edit files with on and off for that purpose). I imported the registry but when I try to reset the default format via Realtek Audio Console, nothing change, and if I try in the device properties, I get a Windows error prompt saying "Format no supported by the device" and there is no audio at all.
Has anything changed with the new version? I hope you could help me with this as I need to set the audio on stereo for playing some games that won't work with DTS Interactive.
As always thank your for your work and support!

@Zitrish: https://streamable.com/4lsbny, not sure where my instructions went in post 1, sorry for the confusion.
@Bryan Ü, you will need to speak to Alan to get his files and instructions at this time.
He confirmed it should work with this pack, but some adapting is needed.

Thank you @Ferather. I have a couple of registry edit files that you shared me a year ago, named DTS Interactive [Off] and DTS Interactive [On]. I don't know if they're the same you are using in the video, but I have tried with these, following your tutorial and I get the error "format not supported by the device when I try to change the format.
Have you update the reg edit files?
By the way, do you still have the version 6.0.9159.1 of the driver? I try to downloaded it with the link I bookmarked but it's down.

The files have likely been updated, or I made them differently for your purpose, Can you send me a link to the files.
Some of the older packages are in the 'previous versions' folder, in the main directly in post 1.
Some have been deleted to due errors, issues within, or un-supported code.

Sure, here is the link with the two files that you shared about a year ago: https://www.mediafire.com/file/lze65umtueys20s/Ferather_reg_edit_DTS_on-off.rar/file
These files work perfectly on 6.0.9159.1 version of the driver.

I don't seem to be able to extract the .rar, but if it's the one that has 'Software/', its now 'Software/DTS/APO/XXXX=0', check using regedit.
If its the above version, you will need to reset all endpoints using 'FX Config', to reset the device.
After you have edited the original .reg files with the updated one, it should work.

yes his is more streamlined and focused on high quality DTS enchantments through spdif with less of the post processing apps for me its best quality sound you can get from spidf i have seen really the last step he has is full dts:x home theater support on spidf but his driver allows dts:x ultra enhancements on top of dts interactive so you get as close to DTS:X as possible over a normal DTS stream its one of the most light wieght driver packages out atm with some of the highest sound quality really cant go wrong

@gabsvm, What @ajf64 said, (thanks for the kind words), however some people do prefer Dolby and other enhancers, so is it better, yes and no.
For me it is better, and I have focused on delivering best possible audio quality and lowest delay, on both analogue and digital.
Someone who prefers for example Atmos, and also perhaps Sonic studio, would probably pick Alans pack.
Some people have mentioned they prefer the DTS Interactive:X version over DTS:X on HDMI, regardless of compression technology.
----
Some side notes for new users:
The older provided Sound Unbound comes with a license and in an 'as is' state, it will try to set the device to stereo on app open *.
You can use the retail version (purchased from the store) with the driver with full support, this is suggested.
The license you purchase also covers a large portion of the driver its self, and can be used on 10 computers.
If you mostly use multichannel, both apps are largely unused, and are optional, the APO's are still active.
* Can be an issue with analogue multichannel setups, and stereo (2 channel) spatial modes.

Yes, the DTS APO enforces 6 channels, you will need the optional files, and Stereo.reg (edited) to switch between APO's, and stereo.
Open 'FX Config', select the SPDIF device and then press 'Copy GUID', edit the .reg replacing both {DEVICE-ID}.
I set the base files as read only, so you will be asked to save another copy, give it a name.
https://streamable.com/4lsbny, once working, re-apply the reg to be safe.
----
If you have E-APO installed, you should also edit the .reg to add its key, or it will be removed, or re-add it via 'FX Config'.

首先，卸载所有以前的 Realtek 驱动程序，包括任何过去的安装。使用 pnputil（请参阅此处）扫描系统以查找残留的驱动程序和扩展。
使用 pnputil 的快速方法是两个命令，“pnputil -e”和“pnputil -d oemX.inf”，X 代表您在屏幕上看到的数字。
您可以检查“provider”、“class”和“signer”来识别任何应该删除的驱动程序。

Nice work on the policy unlock, some of the steps you could have skipped, simply installing the driver then the policy edit would have been enough.
Set the Realtek panel to separate stream for headphones. https://ibb.co/ZG3cC4S | https://ibb.co/L0gD9Q7.
Note, simply double click 'Install', it has been programmed to already run as Admin.

It should already be showing headphones, I guess you have restarted the PC after the changes?
If not, it can be converted to headphones in the registry, but its a bit complicated.
You can use the 'External Speakers' package, converted to headphones, which is 02, not 01.

Its a bit complicated to explain, for what you need, you would need to modify the 'External Speakers' package.
You will also need to make a duplicate, to switch back, which is easier to do than explain.
Speakers is a whole lot of 0 then 01, and Headphones is 02 in terms of Registry ID.
The package comes with a guide for its intended purpose (SPDIF).
----
The package edits the registry on startup, changing SPDIF to speakers for 'External Speakers' in the app, then back to SPDIF.
This tricks DTS into detecting speakers (01) instead of SPDIF (08), without breaking anything (switched back to 08).
----
In terms of multichannel (DTS has two operating technologies), you don't need 'External Speakers' to show in the app.
That includes multichannel SPDIF (DTS Interactive), to use the stereo tech, you do need 'Speakers'.
I use the 'External Speakers' package anyway, in case I want to switch techs.
----
An example of the two technologies can be seen in the 'preset.xml' (feel free to edit), where there is EFX-Eagle, EFX_51-Helios.
EFX is used directly with the stereo tech, where EFX_51 stands for multichannel (5.1 minimum for multichannel).
I have re-programmed the files, to increase quality and reduce delay, all you need to do is edit form factor.
Note: EFX_51 currently supports up to 12 channel PCM (5.1, 7.1, 11.1).
----
A side note (driver selection: Main), SPDIF specifically has been setup with EFX_51, and set to 6 channels (5.1).
It also supports 7.1, over 5.1 (2 virtual side) using the front to rear setup (not front and side setup).
In games and audio applications, you can output 7.1 if the audio is 7.1.

感谢你的回复！听起来很复杂，我只是音响发烧友，但并不专业，我们需要的是实现小白更完整的效果教程，第一步，第二步，第三步，同时附加屏幕截图操作，它会让我们更容易理解，您可能需要花一些时间来教我们如何操作，感谢您的工作，非常希望收到您的效果！

Quick install guide:
1. Remove all previous drivers, use pnputil (see post 1) or other, make sure to remove all extensions (look for Realtek, A-Volute, Sonic studio).
2. Make sure the device is 'missing' (not there) from 'Device Manager', there should be no Realtek devices.
3. [Optional], run a registry cleaner 2-3 times, to cleanup residual registry entries.
4. Double click 'Install' (not right click), Main: DTS Interactive:X on SPDIF, Alternative: Stereo on SPDIF.
5. [Optional], install the provided 'DTS Full Policy' or 'No Panel Policy' (see post 1), if needed.
6. Reboot.
----
You only need to install the policy once, once installed, you do not need to re-install it.
----
Optional files:
DTS Settings: Used to program other audio devices (not Realtek), on the system, such as GPU (HDMI), or to swap SPDIF to stereo (video).
External Speakers: Used to program SPDIF and also HDMI with the form factor 'Speakers', in order to use stereo.
DTS Settings: Once working, repeat apply the .reg file to make sure.
In some cases, open Regedit with FX, then import then .reg.
----
I will make a guide to convert 'External Speakers' to 'Headphones' soon.
