Moving from SMB1 to SMB 2/3: Synology NAS, Windows and macOS | Sonos Community (2024)

I’ve got a Synology DS923+ and have been trying for years on this and my previous RackStation to get Sonos to communicate via either SMB2 or 3.

Every time I turn NTLMv1 off and set the minimum SMB to 2, the Synology logs say “failed to connect via vSMB] due to SMB1 not permitted].

I’ve turned all of the Sonos kit off at the wall, left it for a while and restarted it. Trying to update a music library or re-add the music folder fails.

As soon as I revert to SMB1, it works without an issue.

Edit: One simple change fixed it. I had been using a Domain/LDAP user to access the share. With SMB1 and NTLM1, this worked. Apparently with SMB2 and SMB3, Sonos wasn’t happy connecting.

Reverting to a local user on the Synology for accessing the share allowed the Sonos to catalogue my music and work.

How many years of sitting on SMB1 because of that simple solution?

Have either of you had any issue with the Music library on the new new Sonos app? I have the same Synology setup as y’all

I'm afraid I haven't “upgraded” to the new app because it removes a whole pile of functionality, not least the ability to search your local music library or trigger a reindex.

Thanks @CronoCX. I’ve bookmarked this to link in other threads. You have a done a great service!
