When I initially set up my Sonos ONE Gen 2 speaker it worked absolutely fine. I then got a separate Sonos ONE but without the mic function in order to set up stereo sound.
I'm not sure if it was since then or after but whenever I ask Google to play music from Spotify on my Sonos I have to initially ask it twice - Google will respond saying "ok, playing .... On Spotify" but then this is followed by silence until o repeat the command.
Similarly, when I try to cast from Spotify, I will often choose a song which will start playing, then cast it to my speaker but then have to pause and play the song again before it starts playing.
I don't know where the problem is, but I have noticed others have mentioned similar issues on these forums a year ago. I was hoping it would be a temporary bug but it has now been like this for almost a year.
Any ideas? My Google mini works flawlessly (and has full Google assistant functionality) but I do think the Sonos speakers are better quality so would like to get them to work before binning them off.
