Hi, I tested my Tone 2 using USB and it works fine.
I have an Allo Digione with Volumio, using the SPDIF out to the Tone 2, can’t get it to work. using both input set to “Auto” and also SPDIF on the Tone 2.
Tested the Allo with another DAC and I have good results.
Totally Agree! Just an FYI, I have a Logitech Squeezebox Touch with SPDIF output which I plugged into the Tone 2 Pro and it works fine. Clearly there is something different about these digital output hats. I’ve been meaning to try something other than Volumio. Perhaps Roon or Rune, or whatever it is!
