Bug 490138

Description of problem:

When adjusting volume in different ways, volume changes by different step.

For example we can change volume by hotkeys (multimedia keys on keyboard), by mouse wheel above mixer applet in Gnome, or when slider of mixer applet is opened we can use arrows or mouse whell.
All this scenarios give different volume jumps.

I made table, how many addjustments one need to increase volume from 0 to 100%:
laptop multimedia keys     -  16
mouse wheel on slider      -  13
mouse wheel on applet      -  25
arrows when slider focused -  25
PgUp when slider focused   -  10

Particulary annoying thing is that both laptop multimedia keys and mouse wheel above slider give such a big jumps in volume. Once it is too loud, and after pressing volume down key, it is too silent.

I would like to have at least 25 volume positions for hotkesys, it is somehow minimal precision which is not annoying.


Laptop multimedia keys are managed by gnome-keybinding-properties (Keyboadr Shortcuts) with XF86AudioLowerVolume and XF86AudioRaiseVolume.

I know that in Fedora 10 same problem exists. Especialy with multimedia keys in laptops.


Version-Release number of selected component (if applicable):
control-center-2.22.2.1-1.fc9.x86_64
kernel-2.6.27.19-78.2.30.fc9.x86_64


Steps to Reproduce:
0. try to adjust volume to have music not too loud and not too silent
1. use multimedia keys to adjust volume and listen
2. use mouse wheel above mixer applet
3. use mouse wheel above slider of mixer applet
4. use keyboard arrows
5. listen how volume changes

Actual results:
volume jumps in big steps when using hotkeys and mouse wheel. It needs full focus and devotion from the user to adjust volume properly.

Expected results:
Adjusting volume is coherent and simple. No one needs to be worried of the outcome.
