Frequently my Play speaker pair show that they are connected and playing, but there is no sound and the volume control isn’t working. This is sporadic and not constant. I’ve tried toggling the volume control on and off (it’s off). The wifi connection is good. I'm using the app from my iPhone.

I tried that, and the Office speakers are working, but now the Living Room speakers are having the same problem.
In that case please look at my article:
