According to this article the share is a samba share on your device. Presumably your device is at IP address ‘192.168.1.xx’, so in Volumio simply add it as a network drive Settings>Sources>Add New Drive.
Alias: whatever you want to call the share.
NAS IP Address: 192.168.1.xx
Click on ‘Advanced Options’, and add your username and password for the share (‘cifs’ should be selected by default).
(1) you may need to add one of ‘vers=1.0’, ‘vers=2.0’, or ‘vers=3.0’ to ‘Options’ (without the single quotes) depending on how Samba has been set up on your device.
(2) I’ve never tried the cd ripping facility of Volumio, so not entirely show how it will interact with this network drive. If it works as expected then please report back to let future readers know
