For DAC's based on the PCM5122 chip which includes IQaudIO Pi-DAC+, HifiBerry DAC+ and DAC+ Pro, the two sliders in alsamixer named "Analogue" and "Analogue Playback Boost" are for the analog volume controls on the chip. These controls have only two steps 0 and 100. I forget what the dB equivalents are.
IQaudIO recommends setting both volumes to 100 for their Pi-DAC+ board. HifiBerry recommends setting "Analogue" to 100 and "Analogue Playback Boost" to 0 for their DAC+ boards.
Moode makes these settings automatically during startup for these DAC's.
