Message:

the alsa volume number is soundcard-dependent, and may not be linear;
nevertheless, volume adjust now steps in smaller (yet still noticeable)
ramps of roughly +/-3dB as replicated on current hardware; this may
vary between hardware (check with 'volume-get'); if it does, one can
just grab the dB and ramp the dB linearly by going amixer set PCM XdB
where X is an *absolute* setting
