I have Acer Predator Helios 300 [ I5 / 1650 TI / 144HZ ] model no. PH315-53. I got DTS X ultra pre installed from company but after the update to Realtek semiconductor crop.-Extension-6.0.9054.1 . I am unable to use it while I have plug-in my headphone in the laptop but DTS X ultra always showing message "please  connect headphones to use DTS X audio console ".  while I use my headphones properly in Realtek audio console.
 on the left side there Realtek audio console and at right side there is DTS X ultra audio console  as you can see in Realtek audio console the headphones are pluged-in but in the DTS X ultra is still showing "please connect  a headphones to use DTS audio controls.

    Hiya I found the solution for this problem. It took me 4 days of troubleshooting to solve it. I'll rephrase the problem again. 
    Problem: 
    1. Unable to select Content Mode in DTS:X Ultra
    2. DTS:X Ultra shows "Please connect external speakers to use DTS audio controls"
    3. 2. DTS:X Ultra shows "Please connect a Headphone to use DTS audio controls"
    4. DtsApo4Service service in services.msc is not running despite force start. 


    Possible cause (NOT SOLUTION):
    Updated DTS APO4x Service Component, DTS Audio Effect Component, DTS Audio Hardware Support Application, Realtek Audio Effect Component, Realtek Audio Universal Service, Realtek Hardware Support Application using Driver Easy. 


    Solution 1:
    1. Uninstall all DTS related (DTS Sound Unbound & DTS: X Ultra) using RevoUninstaller 
    https://www.revouninstaller.com/

    2. Delete all DTS registry and left over files using the RevoUninstaller 

    3. Restart your PC / Laptop 

    4. Reinstall latest DTS driver from Acer site 
    https://www.acer.com/ac/en/US/content/support-product/8376?b=1 
    (Search your own model) 
    XPERI DTS Utility (sound) - DTS Sound Unbound 
    XPERI DTS Utility (DTS Console) - DTS: X Ultra

    ------------------------------
    If it still doesn't work, try these: 

    1. Reinstall Realtek Audio driver using the old version (Which can be found at Acer Site as well) 
    https://www.acer.com/ac/en/US/content/support-product/8376?b=1

    2. Redo Solution 1 above. 

    ----------------------------- 

    Before I was able to use DTS:X Ultra again, I did an optional Update in the Windows Setting 
    (Windows > Update & Security > View Optional Update > Check Insyde Firmware update > Update) 

    If you check for Windows 10 Update, it might update the DTS and Realtek version, refrain from updating them to prevent from possible error.

    After struggling a month for this problem. I am coming with a solution will %99 work for everyone.

    It's all about outdated Dtsapo4service.exe and dtscnt64.dll. DTS:X uses these services in order to be working. You can see error reports in Windows Event Viewer.

    1) 
    Download Revo Uninstaller Freeware Portable - Free and Full Download

    2) Uninstall Realtek Audio driver and remove all leftover files and registries.

    3) Uninstall DTS:X Ultra and DTS Sound Unbound from Windows Apps tab. (Remove all leftovers too)

    4) Reboot and do a windows update. Allow Windows to detect and install Realtek driver itself. "DON'T" install the Realtek driver in Acer Support.

    5) Reboot.

    6) Download the Realtek Driver from Acer Support page and "DON'T INSTALL". Just extract the files to a folder.

    7) Go to "(Extracted Folder)\Win64\Thirdparty\20200210(This might be different)"

    8) You'll see folders named like "DTSXULTRA" and "DTS4APO", right click the ".inf" files inside of these folders and press "Install".

    9) Reboot after installing all ".inf" files.

    10) Download the "Latest" DTS drivers in Acer Support page and install them with using "Setup_APP.cmd" inside the drivers.

    AND THIS IS WHERE EVERYBODY GOT STUCK. DTS:X WILL NOT WORK AGAIN UNTIL YOU DO THE STEPS BELOW.
    After researching so much hours, I have found the most up-to-date "Dtsapo4service.exe " and it's ".dll"'s

    11) Head over to 
    DTS other devices drivers download for Windows (32/64bit) (drvhub.net)

    12) Press "Download Driver" inside of "DTS APO4x" and "DTS APO4x Service"

    13) After downloading both drivers, right click the ".inf" files in both of the drivers and install.

    14) Reboot and thank me.

    :)

    Few days back some Realtek audio drivers updated.
    Now, DTS app is still works as per visual. Though I don't get any sound difference when I off/on DTS from app or check different presets.

    Not sure if I should restore back and hide these drivers too or not.
