So the standard response is "don't do that then" :)
That's why the base volume is shown to the user via GUIs so that they
can gauge the best point on the slider to use. Currently there is no
indication with alsa sliders at which point the 0dB "sweet spot" lies.
IMO this is a good improvement for usability.
