I had 4 SONOS connect devices (S1 app only) doing exactly this. I recently (last month) replaced them all with BlueSound node nano devices. They do exactly what you require - point it at the SMB server and away they go.
Bonus is they do it over SMB2 allowing me to switch off SMB1 which I'd previously had to keep running for the SONOS devices.

The SONOS connects are going to goodwill.
