I was using a RPI 3 B with volumio and a DigiOne card without any problem.
I just bought a RPI 3 B+, with the same DigiOne card and impossible to use Volumio.
After flashing I have access to the web interface or SSH, but as soon as I declare the sound output with the DigiOne, I no longer have access to Volumio by http and SSH…
There seems to be some sort of issue. I did a fresh Volumio install on my DIgione/RPI3b+ which was using Dietpi/Roon before without issue. After setup with NAS network access to 44.1/16 FLAC files, selecting I2S/Allo Digione for audio hardware and rebooting, am unable to play music. I can select a first song, tell it to play, song play timer runs but no sync lite on coax connected DAC. If I stop song, timer stops but pause symbol is not replaced by start symbol, can delete queue but cannot add music/resume 1st song
