So I really thought I had this set up figured out. Surround with Arc, Sub and 2 x Sonos One. HDMI connection to HDMI Arc from Arc to projector. HDMI connection from the Apple Tv to other HDMI port of projector. The LG HU80KSW is essentially a smart tv in a projector package. But I can’t get the wired audio connection to work? I only get audio from Airplay which sounds fine, no lag so far. Why is the Sonos Arc not using the wired Arc connection? I know projectors are theoretically not supported, but the LG HU80KSW is just a tv in another format with a normal HDMI Arc connection. I have a feeling some people on here got this to work but I’m stumped. All the right elements are in place. Any ideas on what I might be doing wrong?
