We can try to use an alternate audio driver and see if that helps. Expand Sound, Video, and Game Controllers.If the issue persists, you may want to try updating the Audio drivers and check.

Select the checkbox for Loudness Equalization.Under Playback tab, double click on the sound device that you are using.However, you may want to have a look at the Sound Control panel, and see if Loudness Equalization Enhancement is available. 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 Ideally, the level of audio depends on the type of file that you are playing. I understand that you are unable to get proper audio output levels on certain videos. Thank you for writing to Microsoft Community Forums.
