I2S DAC volume control
#2
All volume controls, analog or digital, generate distortion. The only thing that matters is whether it's audible.

With two volume controls in the audio chain its usually best to calibrate the system to minimize distortion.

1. Set the downstream volume control (on the Amp) down to 0
2. Set MPD Software volume to 100
3. Play a track that represents what you typically listen to
4. Gradually turn up the downstream volume control until the level is the loudest you would listen at

This calibration usually results in no audible distortion when attenuating the upstream volume control (MPD Software) to normal listening level.
