DTS:X Ultra Not working

UPDATE: I do not know if this is just temporary, but I may have seemed to fix the issue on my DTS: Ultra app.

What I did before my DTS: Ultra app worked was to download and install the following updates that were due on my PC, namely: 1) Windows 10, version 21H1; 2) NVIDIA GeForce Game Ready Driver Version No. 496.13; and 3) AMD Driver Update No. 21.8.2. Note: I downloaded and installed everything simultaneously before restarting.

What really fixed the issue, I think, was the installing of the Windows 10, version 21H1. I believe this update has been made available to Windows PCs since May 2021. It's just that I only installed this update today because I thought that it was not necessary for my PC, being considered by Windows itself as an "optional update" only. But hey, look where it got me.

For those who still have this kind of problem, and who prefer not to install Windows 11 yet, try downloading and installing the Windows 10, version 21H1 update. It's safe, and so far, will not give your PC complicated bugs (based on my research). As for the 2 other drivers (NVIDIA and AMD), I think these driver updates are irrelevant in fixing the issue on my DTS: Ultra app since these driver updates pertain to the graphics card of my PC.

So, that is all folks. I hope this helps everyone who may have not have fixed yet the issue on their DTS: Ultra app despite having successfully downloaded and installed the "DTS APO4x" and "DTS APO4x Service" drivers. Also, I would like to thank everyone here who took the time to help the people who are having these kinds of problems, including me.

Hey,
Earlier I had KB5001391 installed, and my DTS :X Ultra app was not working. So I reset my Windows  using the cloud install option, but unfortunately the DTS app is still not working. I thought may be the mentioned KB was causing the issue, so I tried uninstalling it using command wusa /uninstall /KB:5001391 but it says the mentioned KB is not installed on my machine.

I am not sure what else could be the reason.

I have reinstalled audio drivers several times, reinstalled DTS X and DTS Sound unbound app several times, nothing is fixing it for me.

Do you have any suggestion?

I have simply ran Windows Creation tool and used the upgrade option available it it. After Upgrade was completed DTS:X Ultra started working and Paused all the future updates after it.

I don't know how it is related to issue. I was trying to install app from Microsoft Store, since DTS:X Software component was not at latest I was not able to download the app.

Windows 10 apps need either FAT32 or exFAT format.  NOTE: reformatting permanently deletes any pre-existing content.
