It turns out I needed to change the minimum Samba protocol to v1
That does not sound very sensible of Sonos. Samba v1 is from the days of DOS and is now known to be highly insecure.
I dug out this article which says so. Looks like it doesn’t work with Synology DLNA server either. So it looks like Plex may finally make it on my NAS!
