Until the major update to the Sonos App months ago my Arc was happily playing music from a set of music libraries I had set up on a MacMini connected via Ethernet. Then the libraries, and any way of adding them disappeared from the App. More recently the means of adding a library has returned but when I try to re-add the libraries I get the error ‘Unable to connect. Check the user name and password’. I am using the latest version of the App on my iPhone.

Needless to say the path name, user name and password are all the same as used before, and have been rechecked many times. I have switched on and off everything multiple times. I have rechecked all the file sharing permissions & SMB enabled multiple times. In short the only thing that has changed is the App.

As my Arc sits there silent month after month I am getting more and more fed up, when is this going to be fixed.

The library folder sharing protocol has changed - you now need to share the folder using SMBv2 or higher.

Here’s two Sonos Support links and a YouTube video aswell, that each will hopefully perhaps assist you to setup Sonos access to the share…


Have you tried using the app for a PC or Mac instead of the mobile app? There are many posts where users found using a computer worked for them.

When the new app was released and the ability to configure my local library was removed, the app on my Mac still worked to do everything I needed. All the changes were loaded to the mobile app after a restart.


OK thanks, SMB is the issue, my MacMini is limited to macOS v10.7.5, but SMBv2 was introduced in macOS 10.9 - so looks like I need a new MacMini or alternative NAS drive.

Will the MAC support Plex server? If so you could use that. Also if you subscribe to Apple Music you could upload your library to the iCloud and access it through the Apple Service in the Sonos App. A further option is to look at using the iBroadcast service with Sonos.
