Looking online, the only connections I’m seeing to that Samsung Projector are HDMI and Bluetooth.

Sonos products (such as the Amp/Arc/Beam) do not have an HDMI connection, as they use either HDMI-ARC, or HDMI-eARC - so the only way to connect to Sonos seems to be by using the Bluetooth connection (assuming that its BT profile is compatible with Sonos products) .

There are two Sonos devices that are able to connect using Bluetooth and those are the Sonos Move and the Sonos Roam, both of which are portable rechargeable battery powered speakers. You can read more about those at the links below:

Sonos Move

Sonos Roam

The projector cannot connect to Sonos via WiFi but it can connect via Bluetooth to a Sonos Move or Roam. The Roam can also be used as a Bluetooth gateway for the rest of your Sonos speakers.

Thanks Rashi, I tried that way and it worked.

thanks!

Hello @Ricardox ,

I’ve the same problem here, i’ve a samsung freestyle projector and two Sonos One, and i’m enable to connect between them. 

A Roam could be a real solution to play sound of movie in stereo on the Sonos One ? 

Yes, it is possible to pair the projector with the Roam over Bluetooth and then group the Ones with the Roam in the Sonos app.
