Volume attenuation whether its digital or analog adds noise to the signal. The goal of high quality volume control is to make the noise inaudible. ESS has an interesting presentation on how their on-chip digital volume control works.

If you use both an upstream digital volume control for example moOde's Software or Hardware volume control, and a downstream analog or digital volume control you should calibrate the entire system for lowest noise when attenuating volume.
1) Set downstream analog or digital volume control to 0 (no volume output)
2) Set moOde volume to 100%
3) Play a track that represents music that you typically listen to
4) Raise the downstream analog volume to the loudest level you would ever listen at
This generally results in a configuration where noise is inaudible when attenuating volume using moOde's volume control.
