  1. APO Driver 1.0.0 x86 release on baytrail tablet.
    "Could not access network location \APO driver."

  2. After trying to apply any settings on 32 bit baytrail tablet:
    Error: Failed attempt to launch program or document:
    Params: <-on "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\MMDevices\Audio\Render\{7781b85e-e69f-4421-8910-16a51c9bbe32}" -ot reg -actn setowner -ownr "n:Users">

    Specifically: This version of %1 is not compatible with the version of Windows you're running. Check your computer...

    ---> 682: Run,%a_temp%\SetACL%ACLBit%.exe -on "%LoadPath%\%SelectedGUID%" -ot reg -actn setowner -ownr "n:Users",,Hide

    The current thread will exit.

  3. Fixed SetACL 32Bit problem - Version 1.0.2


  4. APO Driver 1.0.2 x86 release on baytrail tablet.
    "Could not access network location \APO driver."
    Note: Is it possible to chain SRS premium sound then Dolby Atmos on same endpoint?
    Currently using fxsound enhancer that has SRS APO applied and High Definition Audio that has Dolby applied.

  5. Redownload and reinstall APO driver 1.0.2
    Save the following file (pastebin link) into SRS_Dolby_UWP.ini on C:\Program Files\APO Driver\Config folder
    Load the config using FX Configurator

  6. 1.0.2 successfully installed on 32bit tablet.
    SRS_Dolby_UWP.ini tested, do not work (SRS premium sound does not load; checked whether it was used on any other endpoint, no conflicts.)
    Don't bother correcting it; I can manage without it.
    Note to other readers: SRS premium sound operates as a 32bit float audio processing. Thus it can go over the 0db audio limit peak. Using either Virtual audio cable or Fxsound enhancer driver requires you to lower down the individual app volume in the volume mixer to prevent audio clipping.

  7. Previously described (SRS_Dolby_UWP.ini usage) was on 64bit Teclast(台电) tablet。
    On 32 bit baytrail tablet, version 1.0.2, SetACL problem still there; nothing can be applied.

  8. Make sure FXConfigurator32.exe version is
    If the SetACL problem still exist, download setacl 32 bit
    rename SetACL.exe 32bit version to SetACL32.exe
    Turn off your antivirus and/or windows defender,
    Open FXConfigurator32.exe, copy SetACL32.exe to C:\Users\YOUR USERNAME\AppData\Local\Temp
    Select the endpoint you wanted.
    Load config SRS Premium Sound.ini and apply
    Since I cannot found 32 bit Dolby UWP API, only Dolby UWP App x64 work (x32 bit UWP App don't work)

  9. Successfully loaded SRS premium sound on 32bit tablet.
    Installer seems to have the wrong setacl32.exe; the temp folder had the setacl32.exe file, but was the 64bit version. Corrected it from the given link, and FXconfigurator32 worked.

  10. On 64bit device.

    The module "C:\Windows\System32\DTSAPOUI64.dll" failed to load.

    Make sure the binary is stored at the specified path or debug it to check for problems with the binary or dependent .DLL files.

    The application has failed to start because its side-by-side configuration is incorrect. Please see the application event log or use the command-line sxstrace.exe tool for more detail.


    This was done:
    Delete ‪C:\Windows\System32\DTSAPOUI64.dll, install again
    If error still popup, just click ignore and run cmd as admin -> type regsvr32 DTSAPOUI64.dll

  12. Disable driver for dts digital entertainment during install APO driver 1.0.5

  13. Proper solution for DTSAPOUI64.dll: Install Visual C++ 2008 x64.

  14. As reported previously:
    Copy pasting KGA files generated on your PC (which is now available for download on your site) over to %ProgramData%\Creative\SoftwareLock will only work on the PC the KGA file was originally generated on, and will not work on others. I'm afraid KGAGen is the only solution for the time being. You could create additional commands to delete unnecessary KGA files to determine whether you want 360 or 720.
    Sir, your kga files will not work elsewhere, except on your own pc.

  15. Hi Alan!

    Could you send me a inf driver which contains creative 720 with Dolby Atoms gaming?

    My email address is koubaisya@yahoo.com.hk


  16. It use to work for me, in the first week of june, but not anymore even in the DAX folder, i don't have RADARHOST Folder when i try to install it like i did before.. Every single time when i ever i try to install your apo driver with dolby atmos for gaming. I always get the error message"There is a problem accessing the dolby atmos for gaming driver.Please restart the computer or reinstall the driver if the problem persist". I install everything correctly, even the right run times and frameworks. I even reformatted my pc several times and use the audio cleaner tools. Please help me out if you can.

  17. hi. please help me install nahimic 3. I did everything according to the instructions, the application worked, but the sound remained the same.

    1. Nahimic 3 UWP app does not work on all hardware anymore as it only works on specific hardware similar to Waves Maxxaudio UWP app. need certain MSI brand motherboard or laptop to use Nahimic 3 as noted on these pages:
      Also Nahimic 3 may also work on certain new Dell Alienware laptops and maybe some new Gigabyte & ASUS boards/laptops. anything else beside these, the Nahimic 3 is not guaranteed to work.

      also the SFX MFX EFX entries in Realtek Audio Effects render INI file in APO driver applies to Realtek HDA (non-UAD) driver only; Realtek UAD drivers use "composite" and "offload" SFX MFX EFX entries as I checked its generic extension INF file. so APO driver can be improved for next version. perhaps include new Creative component version in APO driver for Creative SB Connect UWP app.

    2. a follow up: use latest Win10 version - build 17133 or 17134 (RS4/1803). Nahimic 3 from APO driver works best or runs correctly when running Win10 v1803 and not the v1709 or older versions of Win10.

    3. The kga file don't work on new Creative component. MaxxAudio file has encryption, and maxxaudio is bad: https://www.youtube.com/watch?v=7kZIn-uaoTM.
      Nahimic 3 should work on the lastest stable version of winodws 10 x64, no matter what your CPU or motherboard is.

  18. 請問一下電腦都說這有病毒怎麼辦????

    1. 電腦都說是特洛伊木馬

    2. 關掉防毒不就行

  19. I have a lenovo ideapad y700 and after installing the driver for dolby atmos the internal subwoofer stopped working... What can I do?

    1. Have you try use v2 api and v2 preset? If you still got any problem, replay to this thread https://www.techpowerup.com/forums/threads/making-audio-enhancers-work-on-windows.244309/.
