Sonos has released a firmware update that now supports Spotify Free. With other devices that are "Spotify Connect"-capable, this has been working for quite some time. Chromecast audio devices can also be streamed from the Spotify app with a free account. Sonos users can access Spotify Free from the Sonos app, the Spotify smartphone or desktop app, or via Google Assistant. However, a Spotify premium subscription is still required for targeted access to any title on the smartphone and for offline use – which also offers better sound quality and playback without commercial interruptions.
Spotify Free – now works with Sonos
Previously, the paid "Premium" subscription was required to use the Spotify music streaming service on Sonos devices. Now you can also use Sonos with Spotify Free.
