I just discovered by chance why "Options > Stop: Fade (slow/normal/fast)" was refusing to work in my setup: disabling volume also disables fade on stop!
Is this a wanted behavior?
I would prefer to keep volume disabled but, at the same time, be able to use fade on stop: stopping music would result in an
abrupt and unpleasant change in volume with that function disabled. Strangely crossfade on track change works when volume is disabled.
