I’ve had Sonos gear for about 5 years now. 4 units, great little speakers – when they work!
Case in point, I disabled SMB v1 on my win 2016 hyper-v based file server this weekend, only to discover that the default (as in only) SMB format that Sonos supports to enumerate/connect to windows shares is SMB v1. Yikes!
It’s noted here:

I found it while skimming through 100’s of posts over the past few years on the Sonos customer support forums.
I was about to take to Twitter-bird to chide Sonos for this over-sight, when I noted MSFT Ned Pyle from Microsoft already had!
He’s got this post from last year on the topic
Regardless, I hope Sonos add SMB v2 or v3 support to their units soon. SMB v1 needs to die!
