Acer Swift 3 (SF314-43) – Problems with DTS Audio Processing

I bought a new Acer Swift 3 a couple of weeks ago and I installed Windows 11 (legit, not pirated). First I struggled a bit installing DTS Audio Processing, but then I somehow managed to do it, and it worked flawlessly. Then two weeks later it showed me an error saying "Settings are unavailable as audio service connection lost". I read a lot of articles and topics about this, but nothing really helped. I deleted all the devices and drivers, then I reinstalled them, deleted DTS Audio Processing, installed a few different versions, but nothing. Yesterday I downloaded the newest drivers and DTS Software Components from Microsoft Update Catalog, and updated all of them. Now DTS Audio Processing shows no errors, yet it doesn't work, it makes no difference in the sounds. I spent a lot of time trying to download the exact same drivers, so I think it isn't the root of the problem. Any idea what should I do?

If it happened less than a month ago, open Control Panel. Search 'restore point' Click 'create a restore point' in left pane. If System Protection is turned on, click System Restore button. Click next. Do you see an automatic restore point with a date stamp about when it first happened?
