First post here, apologies if it has been posted before, I searched and could not find anything.
Is it possible to sync/group Sonos and Chromecast so they play audio in sync? I have a couple of Play:5 around the house and a chromecast plugged in the TV feeding into an amp and speakers via toslink and thought it would be very nice to sync them all. I suspect the answer is no, and judging by what I read will never be a feature. If I want to do it, I am going to have to plug chromecasts into the line in and group the chromecasts.
