Hi, I have a new sonos beam and an old Optima HD141X projector. The projector has an audio out, HDMI 1/ MHL, HDMI 2 and 3D Sync out S5 as well as mini USB as per the photo attached. 

I would like to get the beam connected to the Optima projector. What is the best way to do this to ensure best sound quality and also to keep voice control (Alexa)? The beam requires an optical or an HDMI Arc as far as I can tell. Do I need to buy an HDMI Arc converter or some form of HDMI to optical converter? If so what will give the best sound quality? I am planning on having a play 5 (gen1) , a play 3 (gen 1) and the new beam all in the same room. The Play 3 is currently using wired to the projector via the audio in (on the play 3) 

to audio out (on the projector) connector.

I want to create as best a surround sound quality as I can.

Thanks all.
