Can't find loudness equalization

Hi,

Thank you for writing to Microsoft Community Forums.

I understand that you are unable to get proper audio output levels on certain videos.

Ideally, the level of audio depends on the type of file that you are playing. As you have mentioned that you are unable to find Loudness equalization, I would like to inform that certain audio devices and audio card does not provide the Audio Enhancements options.

However, you may want to have a look at the Sound Control panel, and see if Loudness Equalization Enhancement is available. Refer the steps mentioned below:

1. Press Windows Logo key + R, to open Run dialog box.
2. Type mmsys.cpl and click on OK.
3. Under Playback tab, double click on the sound device that you are using.
4. Click on Enhancements tab.
5. Select the checkbox for Loudness Equalization.
6. Click on OK.

If the issue persists, you may want to try updating the Audio drivers and check. Refer the steps mentioned below:

1. Press Windows Logo key + X, and select Device Manager.
2. Expand Sound, Video, and Game Controllers.
3. Right click on the Audio device and select Update Driver.

Article for reference: Update drivers in Windows 10.

We can try to use an alternate audio driver and see if that helps. Refer the steps mentioned below:

1. Press Windows Logo key + X, and select Device Manager.
2. Expand Sound, Video, and Game Controllers.
3. Right click on Realtek Audio and select Update Driver.
4. Select Browse my computer for Driver Software.
5. In the next screen, select Let me pick from a list of available drivers.
6. Check the box Show Compatible Hardware and select High Definition Audio Device.
7. Click on Yes if you get any prompt.

If you do not see any change, you can use Update Driver option and Search automatically to revert to Realtek driver.

Let us know how it goes.

Regards,
