I was using Volumio 2 but switched to moOde audio since Volumio too often wouldn’t work just when I wanted to listen to music. Well, seeing Volumio 3 is out, I downloaded it onto an extra SD card and installed into a Raspberry pi. Well, Volumio would not connect to my Raspberry pi NAS (I have two raspberries) even though my PC and moOde see it just fine. I went through the suggested CIFS options (vers=1.0, or 2.0 or 3.0 or 3.1) but no joy. I’m back on moOde and happy as a clam.
