Ray and Roam 2 multi scenario

Hello everyone,

I would like to buy a Ray and a Roam 2 to:

1. connect Ray on my TV, to watch movies and enhance tv audio
2. have a Roam 2 AND the Ray connected to play music in sync, having the Roam 2 in another room, playing music from my Android phone (Sonos app)

is this scenario possible? Or having the Ray connected to the TV only enable it to play music fro mthe TV?

Moreover, if the previous scenario would be possible, can I add eventually a Era 100 to play music, in sync, also to it in addition to Ray and Roam 2 (3 devices simultaneously).

Thanks!!
