What is a ‘Beamer’? I’m assuming it isn’t a BMW. 

If it is a projector of some type, and has a headphone style (3.5mm jack), you’ll could potentially take that output, and connect it to a Sonos device that has a line in. Once the data is in the Sonos ecosystem, it can be played on any Sonos device in the system. Note, however, that all analog line ins have a minimum of a 75ms delay, which makes full lipsync a challenge, which bothers some people a lot, others not at all. 

A beamer is a projector. A lipsync delay is not an option…
