Ok I have managed to make it work with the R2.72 in Windows Fall Update and ALC1150 on ASUS Z170. You follow the classic procedure by disabling Driver Signature and adding the registry value. All DTS interactive, Dolby Digital and Prologic enabled. You can find the driver here:
https://mega.nz/#!tQFzxCjZ!v0Y2wlkF0JBkdWXJnjQJO--CqqByS3WSLn6r7k_Ex8I
nothing much to work here as with 7 series of old driver it still works for me without any modification on my Z170A with official drivers form Asus , well known fact , the issue is 8 sries of driver which lost ASUS DTS I support . You could spare yourself with trouble and just use that , also explained on my page and even an active link pointed to the official drivers , but as you people cant read or just dont understand ..well have it your way :)
I had a very nasty and aggressive emailing with Asus ( pronounced ANUS from now on) and after some unpleasant exchange this is the answer they gave , obviously they are aware of DTS Interactive issue with ASUS motherboard and new series of drivers but are lazy as FUCK to do something about it :
"
Dear valued customer,


Regarding the below problem, we have forward this case to the responsible department of our Headquarters, in order to examine if it’s going to be a new release of the Audio driver with DTS support. We will inform as soon as possible."

Best Regards

Asus Help Desk"

And if you ASUS users would do some fucking homework and contact this idiots @ ANUS support it all could be over much sooner . ALSO an ACTIVE LINK PROVIDED ON MY PAGE ! Disappointing !

Hiya,

Was hoping for some quick input.

My general questions are:

1.) Is this working? ha.
2.) Should i try an updated driver?

My hardware is a GA-Z97X-Gaming 5 motherboard with a ALC1150 sound device.
Im running this into an old Onkyo AV unit, and im forced to do that multichannel because the unit is so old i think it may only do 720p which makes it so using the HDMI pass through a non viable option. The unit does support DST and Dolby among other formats.
It's a 7.1 system.
Windows 10, pretty sure up to date.

Anyhow, i went ahead and did the user Ngeo install "Ok I have managed to make it work with the R2.72 in Windows Fall Update and ALC1150 on ASUS Z170. You follow the classic procedure by disabling Driver Signature and adding the registry value. All DTS interactive, Dolby Digital and Prologic enabled. You can find the driver here:
https://mega.nz/#!tQFzxCjZ!v0Y2wlkF0JBkdWXJnjQJO--CqqByS3WSLn6r7k_Ex8I
"

That went smoothly and it did create both a DTS and Dolby tab in my audio speaker properties (5.1 though, but im assuming thats correct).

The only weird things are...

in the default Speaker audio formats it does NOT list DTS or Dolby. I expected something like this (this is not a picture of my setup, mine is 'missing DTS and/or Dolby)




and in the Supported Formats page, it doesn't list any of that either. I was assuming i would see something like this.



But instead i see something like this (sorry, this is not a screenshot of my setup, im at work). as you can see its missing the formats tab all together.





I also notice all those 'correct' settings ive run across on the internet are usually under optical or hdmi, and i'm looking under Speakers since i'm running multichannel. Maybe all and all that's the 'problem'. Maybe its all fine.


So, what do you think?

1) Is everything working fine since i do have a dolby and dts tab, its just that i lose some options since im running multichannel?

2.) im running the r2.72 driver. Should I stick with it?


Hope this all made sense. Thanks for any input.

Cheers.

your audio device is not supported or the INF file in the driver package is referencing a non-existent file. check the setupapi.dev.log file inside the \WINDOWS\INF folder and view the contents of that LOG file. also, what is the full hardware device ID of your realtek audio device? it should be something like this:
HDAUDIO\FUNC_01&VEN_10EC&DEV_0887&SUBSYS_10438576 (this is a realtek audio hardware ID on a certain ASUS board)

btw, the modified R2.72 pack does not support newer realtek audio devices made in late 2013 & later

hmm, a SUBSYS ID beginning with 1462 indicates you have an MSI motherboard. what is the model of your MSI motherboard?

The problem with test mode/load unsigned drivers is that some games (for instance: Paladins) have an anti-cheat system that prevents the game from loading when signing enforcement is turned off =\
Is there any way to enable DTS or Dolby without modded drivers?

Good evening,
Sorry for my English.

I have a concern for years, and I understood why my games did not pass in 5.1 to my little decoder Creative DDTS-100 connect to the 7.1 creative kit. on my TV (42 ").
-> My analog PC outputs are already used on a 5.1 creative kit, if I play on the screen of my PC (24 ") for FPS.

I had the case with my old configuration, but on the current one too.
Motherboard: MSI Z87-G45 GAMING (MS-7821)
And GeForce 780TI graphics card.

But it does not use, by default, Dolby Digital Live. RRrrrrr

I just found the mod drivers, with Dolby Digital Live.

I did the procedure.
-Uninstall the old driver.
-Restart with unsigned driver installation.
-Install the Drivers
-Add the parameter in the registry.

I now have the 5.1 optical output on my decoder DDTS-100.

My problem:

I can not find the Realteck interface permitting to configure my speakers.
I tested, only from the configurators his Windows is very limited.

I said, my PC is with Windows 10.
I used the driver: Dolby Digital Realtek Mod Windows 10 Creators Win81_R272, which is only about 90 mega.

My questions:

1) Can I find my Realteck interface?
2) This is not possible in 7.1?

Thank you, for your work, it is unacceptable that it is not available by default.

still not working. Do you know how to fix this? Thanks in advance!

First you right-click the XFI MB5 icon and select Exit. Then you should go to the "%programdata%\Creative\SoftwareLock" directory and delete all the files in it.
Once this is done, open this file in 7z format and extract the executable into the same directory mentioned above (please disable your antivirus before this operation because it is only a false positive).

Link for 7Z archive

After the extraction, run it and it will regenerate the same files that were deleted. After the process is finished, delete the executable that you extracted in the directory you mentioned, and then open Sound Blaster again through the Start Menu\Creative\Sound Blaster X-Fi MB5.
Ready.

Hope this helps

Hahah good luck with that soon enough you will have requests for Linux, android, W95 and all sort of shit mixing virtual 3D audio and real multichanel from people that dont recognize diference btween their head from ass yet alone diference btween real multichanel audio and true one, mixing SRS, Dolby Atmos, DTS X and all sort of shit together possibly and presumably on W7 32bit oh! not to mention special idiotic requests to make a specific driver that will magicaly turn their cheap 2ch audio laptops in full hardware dolby atmos, DTS interactive, Dolby Digital Live no matter if they dont have optical out because "encoding" doesnt have any meaning to them and hardware capabilities... Wtf is that????? .. Just give me the magic. Like I said Good Luck

For those who don't know (or haven't tried yet). There are updated Realtek drivers that work as expected (at least for me and several others) in the below link. No fuss to install. Both DTSi and DDL! encoding + Dolby theater work great (nothing is missing) I'm using the official Microsoft Catalog driver 6.0.1.8302 officially signed and WHQL tested. This one includes the latest ASUS installer with the updated encoders (submitted by Asus to Microsoft). The only thing I had to do was uninstall my "hacked" unsigned Realtek driver (which had DTS missing), reboot, then install this driver.

Edit: No weird registry setting hacks necessary.

https://www.techpowerup.com/forums/...10-dolby-digital-live-dts-interactive.228612/

There are even newer drivers dated April 10, 2018. However, I preferred to use the latest WHQL tested drivers from Microsoft (which included the Asussetup installer needed for dts ddl encoding

That link you posted leads to this post. Just wanted to point that out. I hope you update the link soon I would like to see these updated drivers as I keep having issues with the EXTRA apo style ones.

I didn't realize that I posted the wrong URL. Sorry about that! I didn't realize this until I just got a notification for this forum thread today. Here is the URL below... just download the official Microsoft Catalog driver (which also includes the latest real "working" Asus setup installer to install the appropriate licensed DDL/DTSi encoders). Youll have to uninstall any hacked/unlocked Realtek drivers, reboot, install Asus setup, reboot if necessary, install the official Microsoft catalog driver. You wont need to do any weird registry edit hacks or anything like that since these drivers are signed by the right people and work.

Keep the below URL bookmarked; since the latest working drivers get posted there. I wouldn't install any of the beta drivers that are newer than the one Microsoft Catalog driver package since they're not signed by Microsoft/Realtek.

SOUND BLASTER CINEMA 5 (Updated)
==========================

Link is below

http://www.mediafire.com/file/tbxdqlofgv7humn/Sound_Blaster_Cinema_5_%28Updated%29.zip/file

Sound Blaster Cinema 5 - Temporary tips of reduce high cpu usage by SBC5
----------------------------------------------------------------------------------------
Temporary hack to minimize high CPU utilization by 'Creative.UWPRPCService.exe'
----------------------------------------------------------------------------------------------------------


I think reason behind 'UWPRPCService ' high usage of CPU is because of it's high quality audio output with amazing crystal clear surrounding sound

Don't need to abandon SBC5, neither u need to use additional audio enhancer on top it, SBC5 is more than enough

No need to worry about this issue, just follow this simple steps, & enjoy using SBC5

UWP Service utilizes 25% of CPU, use sbc5 when required, see instructions below

Search for 'Services' from search box on Desktop, Open services, Right click on 'UWP RPC Service'

Select 'Properties', set Startup type to - Manual, apply & ok

When you want to use SBC5, Open Task Manager, go to services, right click on 'UWPService', click on 'Start'

To stop, right click on UWPService, click on 'Stop'

Someone in the Notebookreview forums created some recent modded Realtek audio drivers for Win10 (RS1-RS4) that have Dolby DL + DTS + SBX720 for those using Sager / Clevo laptop PCs {download link}

lucky them :)

I don't think I ever got around to posting in this updated/new thread. But if you just want Dolby and DTS working on Realtek Optical output again, here's my instructions that still work on (I believe) just the drivers Windows automatically installs, or Realtek R2.75 / R2.78 and maybe newer. A registry edit is probably needed (Might depend on your motherboard), but Test Mode is not needed. The modified R2.75 DLL is attached as a RAR that can be extracted with winrar since techpowerup won't accept DLLs as attachments.

This needs to be re-applied every time a major W10 feature update happens. It's easy after you've done it before. Also, I believe the "unblock" part in step 3 only applies when the computer still sees a DLL as being from a different computer. However, using a method to "unlock" a file that is "in use" (to remove your unmodified DLL) probably needs to be done every time.

And again, this might still work with whatever driver Windows installs for you, but if not - this was for Realtek R2.75 and some drivers after it.

Yes!!! The fix for Realtek surround on Windows 10 is now in the Windows Insider Slow (and Fast) Ring! And both methods still work!

I'll repost my instructions for the non-Test Mode method here.

2.79 drivers with the modified 2.75 dll. I rebooted after every single step (even if possibly unnecessary). If you follow the instructions exactly, it should work for you.


1. 2.79 installer -> uninstall, reboot, install, reboot

2. regedit -> HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows/CurrentVersion/Audio -> New DWORD (32-bit) named DisableProtectedAudioDG and set it to 1. Reboot

3. Delete the RltkAPO64.dll from "C:\Windows\System32" (Personally, I used a little program called File Unlocker to delete it while it was "in use") and replace it with the modified 2.75 dll (Make sure it's called RltkAPO64.dll Older versions are missing the first l). (Now, previously there was an important step to right click on the dll and open its properties and check unblock near the bottom. That's not there anymore and I haven't had an issue yet, but you might want to check for it.) Reboot


I'll attach the modified 2.75 dll with the proper name here in a rar, but you can get the 2.79 drivers yourself from the Realtek website.

If you've done this before on your computer, it probably only requires 1 reboot total when you're re-applying it after a big W10 update, but still needs that registry edit and file switch.
