https://wiki.ubuntu.com/Sound#Sound_menu discusses the behavior for scrolling on the volume menuitem and scrolling on the title:
> Whenever the volume item is highlighted: > > The Left and Right arrow keys should instantly decrease or > increase the volume, respectively, to the nearest 5 percent step. > > The “-” and “+” keys should instantly decrease or increase the volume, > respectively, to the nearest 5 percent step. > > Rolling a mousewheel up or down should increase or decrease the > volume respectively, 10% per click. and > As a hidden treasure, when the pointer is over the title, whether > the menu is open or not, clicking a mousewheel up or down should > increase or decrease the volume respectively, to the nearest > 10-percent step. By my count, the volume menuitem seems to be correctly following the spec, requiring 10 mouse nudges to go from 0% to 100% volume. The title takes something like 16-17 nudges, so the IMO the right way to make scrolling consistent between the two is to make title scrolling follow the spec. There is a second bug here that intersects with bug #1226931: the left/right and -/+ keys don't follow the spec at all, so there's currently no simple way to walk the volume in smaller steps. -- You received this bug notification because you are a member of DX Packages, which is subscribed to indicator-sound in Ubuntu.
