once i upgraded the OS of my linux box its SAMBA service is not recognized anymore by my Sonos connect:amp device - while the same setup worked just fine for years.  no browsing in the directory tree, no music library update, no playing of any music files, nor mp3 nor flac…

the crucial difference i assume is in the SAMBA version, now at 4.15.5 which does not come anymore with the ancient SMB1/NT1 protocol the connect:amp relies on.  is there anybody out there that got the connect:amp work with a modern SAMBA version > 4.11 ?

here a few elements in my smb.conf file that helped in the past to make this work :

client min protocol = NT1
server min protocol = NT1
ntlm auth = ntlmv1-permitted
follow symlinks = yes
wide links = yes
unix extensions = no

any help is greatly appreciated !
