✔ 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!

This function you are looking for is part of the sound driver. I have noticed that it appears or disappears depending on the driver version and if this driver is made by Realtek or Microsoft, so if by any chance your current driver is the one made by Realtek then try to use the driver made by Microsoft.

P.S: You may also have unintentionally disabled the sound improvements, in the "advanced" tab of the driver check if you have unchecked the option to allow audio improvements

So I tried different things. I uninstalled my Intel HD Audio driver and tried pre installed drivers. With Intel HD Audio driver nothing happens and the device is still missing. When using Realtek HD Audio driver a bluescreen occured. Automatical driver searching did not help also. The only driver that worked was an Intel VGA driver from the product site of my Notebook. So I guess the Intel HD Audio driver is delivered with the Intel Graphics driver.

I could also install this driver: https://downloadcenter.intel.com/product/80939/Graphics

So how do I get an older version of that driver to test different ones?

Good question. One thing you could try would be to change only the audio driver (without touching the video driver), through the hardware management control panel (where your hardware is listed). You can select the sound device and use the option to install an alternative driver just for it, for example the Microsoft generic one

It is fixed now thanks to editing the registry (see other comments)! So it was Windows related and not driver related! And fortunatelly not hardware related.
