Brand new user, have current version on Pi3 running Volumio’s own Pi Linux OS.
Got it working, using hotspot for the moment, connected to my windows machine, copied a few music test files to /data/INTERNAL.
Rebooted the Pi. Made sure permissions were 777, and ownerships of the INTERNAL folder and music folders were volumio/volumio.
I have tried settings → Sources → Scan many times, re-booted, etc. Volumio is not scanning the local folder on the SD card. There are .mp3 files in the folder.
Any tips please? It’s not permissions or ownerships.
