Sonos made a big hubbub about its first voice-controlled speaker a few weeks ago, which makes the Sonos One not having Alexa support for Spotify out of the box all the more suspect. That will change by December 21st as the speaker company says it will push an update enabling "full voice support" for Amazon's digital assistant before the self-imposed deadline. Meaning, it could be around seven weeks longer before your free Echo Dot will take advantage of everything a Sonos speaker can offer. It isn't clear if this is the timeline for Alexa control on older Sonos speakers. At the moment, you can only start music with either the Sonos or Spotify apps. Oh well; this is the future we live in. The update should be out in time for your winter solstice playlist, at least.
