You may try app called Equalizer APO. It can be downloaded from official repository here: https://sourceforge.net/projects/equalizerapo/ After running the application all you need is setting Preamplification to 5-10 dB (marked red in attachment). I also use it to improve sound quality when using different headphones. That’s why I have several Equalizer presets defined.
Thanks. This work for my Mix Plus
Really superworks! For me it is a very good solution! 100%
I bought a super tempered glass, it is better than the plastic one. Fit perfect also with the keyboard, whit glass it is totaly eliminated the little free play between screen and keyboard
