Hi - looking for help.  I’m reasonably computer literate, have built my PCs.  My Sonos system is on S1, with two Connect amps, one connect, one Play 5, one Play3, 2 x CR200s, iPhone app and desktop app (win 11).

I gave up on using my Synology NAS with my Sonos S1 system over a year ago as I couldn’t get it work with Sonos any more due to the SMB issues (after firmware update from Synology).  I’ve tried reading every related thread but I can’t make head or tail of most of it.  Is it now possible to connect to my Synology  NAS (SMBv2 I believe) or am I still locked out?  If there is no way to make this work with S1, my possible “solutions” seem to be :

(1) put music on a USB drive connected to the router (my router doesn’t have a USB port though, and the possible new ISP I am looking into doesn’t provide one either)

(2) keep music on my desktop PC and leave it on on all the time (don’t want to do this for obvious reasons)

(3) Buy a low cost, preferably fanless mini PC, add it to the network by Ethernet, put all music on an internal or a connected external drive

(4) build a raspberry pi server and USB drive (not going to happen)

(5) Replace all my Sonos gear with new (not going to happen)

I would welcome advice in intelligible language - if that’s possible!  Thanks.

S1 is never going to be capable of supporting SMB v2 or above.  The Linux kernel upgrade required for SMB v2 will not fit on the S1 only hardware.

Thanks, and yes, I get that.  So do you have any suggestions?  I believe my Play 3 and one of my Connect amp units (later version) are compatible with S2.  That still leaves me a lot of cost to “upgrade”, from perfectly good units.

What about my other solutions? Router plus USB drive, mini PC on network?

If I switch to S2 at considerable expense, will I definitely be able to access my music share on my Synology NAS?  I have about 1000 CDs stored as FLAC, and I really don’t like having to use Spotify etc.


Any solution that doesn’t use SMB v2 or above will work.  S1 can connect to a music share two ways - via SMB v1 on an NAS drive, or via HTTP on a PC or Mac. 

If you switch to S2, you would be able to connect to any NAS, PC, or Mac via SMB v2/v3 sharing. 


Having looked at “upgrading” to S2 (I don’t count it as a real upgrade, sorry Sonos, more of a forced upgrade) it seems I can do the following without spending vast sums:

One of my Connect:amp units is S2 compatible

My Play:3 is S2 compatible

That leaves one Connect:amp, one Connect, and one Play:5 to replace.

I can buy S2 compatible Connect units on the used market for about £100 each, and replace my Play:5 with a Play:3 for about £80.  I haven’t seen a used S2 compatible Connect:amp yet, but I know they are out there, otherwise I could use a Connect and a small Chinese power amp (Amazon £50)..

I can sell my existing units, to offset some of the cost.  Does this all sound like a good idea?

Does anyone know if CR200 controllers work with S2 (I have two, fully working)?  Or am I then limited to the iPhone app?

Thanks again for any input.


Most listeners feel that PLAY:3 does not sound as good as PLAY:5.

CR200 does not support S2.


It should be possible to ‘downgrade’ your Synology kit to work with SMBv1

I use a 213j as my music server to feed my S1 kit. I also have a 224+ that runs my main data backup, which I deliberately don’t upgrade to work with SMBv1 for security reasons.

My 213j only holds music files, nothing else.
