Is there any way to change the volume increment or ticks? With the default settings, the ticks are way too broad for my taste - one "tick" changes the volume by a large amount, I'd prefer finer control with each tick only increasing the volume by 1-2%. I found in Ubuntu 16.04 documentation for setting in dconf '/org/gnome/settings-daemon/plugins/sound/volume-step' but that doesn't seem to change anything.
Worse case scenario, I can create a custom mapping to change the volume using amixer, but I'd prefer to have the slick UI volume bubble pop-up. Any suggestions?
