Error to reache the file on NAS

Hi to all!
I’ve got volumio on a Raspberry Pi 2 that stream music from a Synology NAS (USB station 2).
From some days ago I’ve faced with issue; the interfeca let mo choose and add musci to the queue, but when I pressa the START button it gave me back the following error:

If I try to reach the file on NAS form PC is ok insted.
What I can try to do to fix it?

Thanks,

Francesco

The error message is “complaining” about the output device, not a file. What have you changed (updated Volumio??) Do you have an output device selected in the settings?
