> Sometimes you want the same thing in multiple places to help usability.
Not when those multiple things do very different and conflicting actions in very very non-obvious manners.
If you have:
1. Mozilla Browser volume control and mute.
2. Gnome Volume Control and mute (that ties into your volume icon and multimedia buttons)
4. Low-level Alsa volume control and mute.
5. Speaker volume control and power.
Now you open up a youtube video. You get no audio.
Tell me, with certainty, which control, or combinations of controls, you will have to use to make the sound audible.
There is a difference between having 3-5 different places to control volume vs having 3-5 different controls you have to use.
