try chevolume might give you a little amplitude ,, also check all sources of sounds ,, video player ,, windows volume by the clock ,, and if you have a realtek software it will also have the volume control in there aswell ,,
Also if you right click on the volume by the clock , click on playback devices , go down to speaker or the hdmi ,, (where ever your sound is coming from )
Right click ,go Down to Properties .. Enhancements tab on top ,, check box with loudness equalization <<<<< That will boost it at leat 20-40 %
