How to update your Sonos system
Keeping your system up to date ensures you have access to all the new features, music services, and player updates that Sonos releases. When a new software update is available for your Sonos system, you will be prompted to update with an “Update Now” button on all of your Sonos controllers. Simply click the “Update Now” button to begin the update process.
To check for updates manually:
Sonos Controller App for iOS or Android: Touch “Online Updates” under the “Settings” menu.
Sonos Controller for Mac or PC: From the “Sonos” menu (Mac), or “Manage” menu (PC), click “Check for Updates”.
On a Mac, the “Sonos” menu can be found in the toolbar in the top left corner of the screen. On a PC, the “Manage” menu is found at the top left of the Sonos application.
