I manage to mount the shared folder where I store my lossless music library from my Synology NAS (DS214, DSM 5.1) using NFS protocol through Volumio web interface.
I guess the folder is mounted properly as I got the green sign next to it. Unfortunately my database is still empty. I can’t see any of my folder.
I waited several hours in vain (I have only 80GB of FLAC so far, not that much I believe). Rebooted my raspberry a few time, I can’t get it work. Frustrating as apart from that it’s working very nicely already with the web radio with my external DAC!
