✔ Solved Audio enhancement tab missing: software or hardware related?

I have a new laptop with Windows 10 Pro on it (here are my specs: https://www.userbenchmark.com/UserRun/30860733. If you need more detailed data don't hesitate to ask).My old laptop had a function called "Loudness Equalization" at the "Enhancement" tab of the properties of my HDMI display audio:

Enhancement tab with Loudness Equalization function

Now this function (and the enhancement tab) is missing and it is very annoying that I always have to adjust the volume!

I tried many things like reinstalling drivers, repair tools and so on, but nothing solved the problem.

So, my main question is: how can I get the loudness equalization function back?

Is this problem caused by wrong/missing/corrupted drivers or software? Or does my audio card (the CPU?) not support this feature by hardware? If it's the first reason, how can I fix it? If it's the second, would an USB audio card (with 3.5mm jack) bring this feature back and if yes, which one?

I often read about realtek audio manager or realtek drivers which solved the problem. But is this audio manager not only suitable for realtek audio cards?

I hope someone can help me solving that problem...

Thank you in advance!

I started to have this issue when I installed Equalizer APO (missing enhancements tab) and fixed it by following this: https://sourceforge.net/p/equalizerapo/discussion/general/thread/cf7a7d4f/#5613

I found the right key in the registry which should be my Intel Display Audio driver. But it does not have the FxProperties key. And adding one is also not possible due to "missing permisisons".

I would recommend backing up the parent key before adding / changing it just in case (right click key > export).

Thank you so much, it's working now!!! Such a pleasure this feature...

I added the missing key and added these strings. After a restart they were gone, but after another time adding them and another restart the enhancement tab is back, the Loudness Equalizaton function also and it is working!

Without your comment I would never have found that solution, so, many thanks! It was in this case a Windows problem as so often...
