I am attempting to set up a music library to use on my wifi based Sonos system. I have moved a copy of my iTunes music collection to an external USB 2.0 drive (Seagate FreeAgent GoFlex Drive) which is attached to the USB input on my AirPort Extreme (ac version).
On my MacAir, I can see the drive as a shared drive, and I can access all the files, including the music files.
In my Sonos setup, I have tried to identify the drive and files as the source of my music. In identifying the device type, I have chosen
on a networked device such as a networked attached storage (NAS) drive
I am then prompted to
Type the path to your networked share:
Examples are given, such as
But what is my path? When I look at the description in Finder on the MacAir, all I see is Server followed by
afp://MyName's AirPort Extreme._afpovertcp._tcp.local/MAC FREE/free agent backup/FreeAgent GoFlex Drive/iTunes/iTunes Music
Clearly the formatting is different from the example paths offered. When I enter this entire string (and several shortened modifications), the dialog box does not recognize the string at all and no Next button appears.
When I modify the string and remove afp:, the Next button does appear. This is followed by a login for the Airport Express (which I input), but when I go to the next screen, I get the message
The computer [the address I put in follows] cannot be found.
How do I show Sonos where the networked drive and files are?
