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.
