Hi,
with Synology 216j and using minim-Server or audiostation I can find only a limited part of my music. The listing of library ends with the beginning with “L”.
What´s the problem?
What´s the solution?
Best regards!

Sorry, it’s not clear to me how you are using the extra software (know nothing about them) with Volumio. I take it you are not just adding your NAS as a network drive to Volumio. Please give as much information as possible when asking for help … you are very familiar with your system, the rest of us aren’t
