If your network drive is mounted but My Music shows 0 items, Volumio is not finding any music files in the configured folder.
Go to
Settings→Sources→Network Drives, edit the drive and check that the path points to the folder that contains your music.If you're not sure the settings are correct, remove the drive and add it again.
Restart the device from
Settings→Systemand wait for the library scan to complete.
If the library still shows 0 items, send us a log and contact our support team.
