Cambridge cnx v2 e Sonos Beam

Is the Cambridge CNX v2 a streamer? It is unlikely to be a direct connection to a Sonos Beam. The Beam is expecting an ARC input, not a standard HDMI audio input, although Sonos does have an optical adapter, so if your Cambridge device has an optical output, that could work. But Sonos’ own software is a capable streamer in its own right, not sure why you would want to connect a third party streaming device to a Sonos.
