I have a RPI 3 + Allo Kali + Allo Piano 2.1
I have just downloaded Volumio 2.31, set output device to Allo Piano 2.1 and Dual Mono and in the volume options I have set Mixer type to None and also noticed that Max volume level is set to 100. I also turned audio sampling on to re-sample to 32/768
Out of interest I activated SSH and had a look at the alsamixer and noticed that the Master Volume was set to 46 (-20.00 db gain), the Digital and Subwoofer settings were also set to 46.
Is this correct as I understood that messing with alsamixer loses bit perfect reproduction (although I know re-sampling also does this). Or is this a Volumio setting?
