hmm, you don't seem to understand... unless i have an app that
constantly plays back something (game or music player) the role used to
play back my sound is never activated. in case of sound effects in an
app the volume control points 99% of the time to the main system volume,
not to the role your app uses to play back the effect. if your slider
adjusts "the active output role" it will always adjust the main volume,
not the volume of your sound effect.
to visualize what i mean, perhaps do the following:
* install the OMGUbuntu app
* turn the main volume down so that the indicator icon just doesn't show any of
the curved lines in front of the speaker icon (30% or so)
* open OMGUbuntu
* keep your eyes on the indicator icon and tap a link/photo/etc in the app
(that generates a sound effect)
you will see the volume jump to full volume the moment the effect plays back,
your role just changed.
if the app had a slider in its settings for controlling the effect volume this
slider would never control the volume you actually want to control, unless the
slider element has an option to define it (this element can indeed default to
the currently active role if unset, but unless you actually want the main
control or unless your app constantly produces sound you would want a way to
override this default to point to the correct knobs suited for the application)
