Have a  Sonos one, which is controlled with Amazon echo dot, I've bought a SL which I want to pair with the One on stereo. I've never used the true play thing with the one as it just looked a gimmick. Place I  bought SL from recommend trying it. Do I do it individually with each speaker or when there paired in stereo. Oh and o do know the One has a mic, but us it's easier to use the echo dot, with the mic on the Sonos we had to shout to get it to work. Advice on Trueplay appreciated.
