Sonos has released a new system software. The software for your Sonos speakers has version number 14.6. This update is for the newer S2 system and the changelog talks about Sonos making changes to the Roam’s set up to improve the overall setup experience.
Probably an improved onboarding. There are also the usual bug fixes and performance improvements, but also a new feature. Users can change the volume of the beam’s treble channels (Gen. 2) after the update.
