SONOS Speakers & Music Library

Hi

My SONOS setup is as follows;

1 * Play 1 (not hard wired)

1 * One SL (not hard wired)

1 * SONOS Boost (hard wired)

All running S2

1 * TP link network router

SONOS App running on IOS and Windows desktop

I predominately use my setup to access a “ripped” MP3 music library that sits on windows share on a Windows 2012 server configured with SMB2. The SONOS app has been configured to use this as a music library - all has worked well prior to S2 upgrade. Now when selecting tracks they play erratically - on IOS give a “Content unavailable” / on Windows gives “an access denied” type error. A track that didn’t play one minute will then play if I try again 10 minutes later - all totally inconsistent and no pattern to any of it. Checked and rechecked share / NTFS permissions to Music Library location - all ok. Checked Windows 2012 firewall rules - all ok.

After spending 45 minutes on a call with SONOS - they have told me that my setup is not a supported configuration. They class a Windows 2012 server as a media server and those are not supported with S2 - only dedicated NAS drives are supported apparently.
The support guy was getting “this information” from internal documents - has anyone seen anything in the public domain that states this configuration is not supported? - I can’t find anything!

This is where I need some some help;

1. I have asked SONOS for a list of compatible NAS drives that will satisfy my use case - what has been tested and deemed compatible? They can’t tell me - only response is that “any” NAS that supports SMB 2 “should” be ok.
   As a community can you advise on NAS’s out there that you have experiences of that will do what I am asking? I want the confidence before I “splash the cash” that whatever I buy will work.
   I don’t really want to go down the PLEX route - overkill for what I need. I just want to be able to consistently access a “relatively small” external music library from the SONOS IOS app.
2. As a workaround I have downloaded and installed “SonoPhone for SONOS” - very impressed with this so far - it does exactly what I would expect the main SONOS app to do and meets my requirements - it accesses the Music library on Windows 2012 just fine.
3. Downgrading to S1 was proposed by SONOS - would prefer not to do this - seems a backward step.
4. Does anyone know if the issue with “tagging” that is displaying each artist on a compilation album as an individual album in the “SONOS Music Library Albums” view, is on a SONOS development backlog? I mentioned this to the support guy and he knew nothing about it. I know you can mess around with the tags to fix - not sure I want to do that though!

TIA
