Obviously, actually having bluetooth speakers with the Echo Dot is a much better solution, but after using the Sonos setup for 3-4 weeks I must say that it works surprisingly well, and despite the audio hack the sound quality is excellent on my Play 1's.
Meh... the problem with Bluetooth speakers is that many of them don't handle the always-on use-case.
My soundbar would work well, but Alexa would get muzzled every time I turned on the TV to watch something. On the other hand, my portable bluetooth speaker will run out of battery if left on its charger.
The AUX connection is almost a better option, but then am I supposed to leave my amp turned on all the time? There's also the same problem where Alexa loses her voice when I switch the amp over to the Bluray player.
