In order to play to multiple rooms in sync (“rooms” meaning individual Sono devices/pairs), you need to group them together.  Grouping is a dynamic process, and does not survive a system reboot or a power failure, which may be the cause of your symptoms.  See below for instructions on grouping/ungrouping rooms:

Note that Sonos does have a “Zones” feature that semi-permanently groups together rooms as “zones”, which will survive a reboot.  There are some limits as to what types of devices/functions can be used in each zone.  See below:

How did you set them up? As a zone, as multiple rooms that ar e grouped?

Unsyncing or not playing can also be an indication of wifi interference . Beyond the information in the linked FAQ, I’d recommend that you perform a network refresh, by unplugging all Sonos devices from power, then performing a reboot of your router. Wait two minutes, then plug back in your Sonos devices. Wait another two minutes, open up your controller and check for and apply any updates necessary, then test.

I just noticed your account name. Are you using these speakers in a large group setting? As has been explained many times, humans tend not to be conducive to WiFi signals, as they’re large bags of WiFi frequency absorbing water, essentially.

Try using Ethernet cables rather than WiFi.
