Playing sound from phone to Sonos? Noooo! Way too basic, the app won't support. Stream from Youtube or your favorite app? What are you, a peasant? I don't understand how it works and I already lost interest. I let my wife try to use her overexpensive, unefficient new speaker. She's been trying for an hour without success. Couldn't care less. That's what you get for buying "fancy" stuff.
