I have a RP3B new out of the box set up and running(using it here to write this) and I have several Synology NAS drives in the house. I am a bit of a MS fanboy so have no problem getting the NAS to work with Windows machines.
I have tried several different sets of instructions online but all fail when it comes to reboot the RP3 it hangs up on the boot phase.
All I want is a folder on the Desktop mapped to my Synology NAS folder with my music. I can then use VLC player and my HiFiberry hat to listen to my music.
all you need to solve the requirements,
is found at runeaudio volumio or moode
try them all to see what type works best for your taste,
they are a little bit different in look and feel, but basicly they are all a super nice and easy to use music player,
sound media centre, if am super happy for playing with this.
