Several folks have noticed that their Samba server stopped serving files to their Sonos v1 Music Library after upgrading to Ubuntu 22.04. After a whole lot of tinkering I found a fix:

add “unix extensions = no” to the global section in the smb.conf file. That’s needed in addition to enabling SMB or NTLM v1 protocol, something that’s been necessary for a couple of years now.

I have a couple of links with more info and will post them as a reply.

Thanks Nelson for debugging this issue together with me, let’s play some music!


I wrote up my notes on this problem on my blog. There’s a lot more detail there.

There’s some discussion of this problem on the Samba mailing list.

There’s also a possible alternative for Samba; Adobe has a Node version of an SMB server that’s up on Github and seems compatible with Sonos v1 systems. Lots of notes about this sonossmb solution here.
