How to change the step of volume scroll in VLC?
CTRL+P --> "Show All settings" --> "Audio" --> "Audio output volume step = 6,40"
With this, you get 2% volume step... (1% = 3,20)
Actually, by default it steps volume down by 5% with a value of 12.8. Changing this to 6.4 steps it down by 2.5% and changing it to 3.2 steps it by 1.25%. So to get it to step volume by 1% you should change the step number to 2.56. Just tested it and I get the gratifying granularity of 1% increments.
