The first few reviews of the Sonos One are emerging.
Unfortunately, there were a few times I ran into some strange and frustrating bugs -- the speaker wasn't recognizing that it was playing music, so "pause" or "next track" requests didn't work. Amazon Music also occasionally got confused and told me it was playing on another device so it couldn't play on the speaker I asked for.
The process of enabling Alexa was a different matter and left me, a tech reviewer, feeling pretty stupid. Alexa could answer general questions and control my smart lights just fine within minutes, but would give me a “Something went wrong” error when I asked for music (or podcasts) with voice commands.
Once you get things humming, the limitations of the voice controls become clear pretty quickly. The Sonos One can do most everything Alexa can do, but it can't do everything Sonos can do. So, when you ask it to play music, the Alexa living inside the One can only summon streams from the services Alexa supports. If you want to play something from your local MP3 library or one of the 80-odd services supported by Sonos (Apple Music, Google Play Music, Mixcloud, MLB.com), you have to pull out your phone and tap.
All are very complimentary about the hardware (it's a Play 1 after all) but have picked up on the unreliability of the software on several counts and the limited services that can be controlled by voice.
I'd be showing more empathy and urgency if I was Sonos as this will not go away and needs fixing quickly.
A dodgy public beta after so long since the announcement doesn't look good.
