I had a strange issue - I was adjusting the volume for my Windows 10 desktop, and when I pressed the Down Volume in-line button on my Logitech H390 headphones, something weird happened: The volume meter when from 0, to 99, as though it wrapped around and got lower than 0 volume.
After this, my maximum volume was wrong, as though the scale went from 0-100 to 0-30. In otherwords, the volume meter (the black windows 10 meter that shows up) had 100 listed, but the volume was much lower.
I attempted all fixes I could find(such as Loudness equalization, driver correction, and so on,) but nothing fixed it. Any suggestions?
