Jeez, man, I explained that in my original reply.
If I may quote myself:
'On top of that most volume controls should then mark the ALSA 0dB
point as "base" volume on the slider, at what PA then calls -y dB.
That way we will expose 0dB as maximum hw amplitude uniformly on all
sound cards and have a special point on the slider that is hinted to be
the "comfort" point.
This is all explained on
http://pulseaudio.org/wiki/WritingVolumeControlUIs#BaseVolumes'
See? It's all explained there. We still show the ALSA 0dB point on our
sliders, we just don't call it "0dB" but "base volume".
