Not easily, no. If you use a Sonos Port or CONNECT, (using the RCA inputs), there will be a 75ms delay before the sounds are heard. The PLAYBAR would connect with an optical input, if your receiver has such, it would be the best bet. The Beam also requires an ARC HDMI connection to play, most receivers pass through ARC (it’s usually generated by a TV/monitor/projector) but don’t generate it. 

Sonos soundbars are designed to be connected to image generating devices, not receivers. In general, they’re looking for a device that generates the CEC component known as HDMI ARC. If your receiver does have an optical output, and can clamp down to Dolby digital at best, then the PLAYBAR might work for you, assuming the optical babble doesn’t get too long.

Honestly, this is so far from what the Sonos is designed for, I’d be very cautious with my expectations. 

Thanks, I was kind of suspecting that was the case.  I can run a hard wire, just need to put some holes in the wall. 

I’m not familiar with optical babble.  Will that happen within a 20-30ft cord? My goal is to get the sound coming from the screen versus the projector which is behind the viewer. I’m not expecting Dolby ATMOS or anything, but don’t want a video / sound lag either. 

Not really an expert in that. Have you checked Wikipedia?

You certainly can’t pass either Atmos bandwidth through an optical cable, but Dolby Digital fits fine. And because the optical input is digital, there would be no noticeable lag, until you grouped another ‘room’ with the PLAYBAR. 

A high quality 30ft TOSLINK cable should work. I’ve used 45ft for a PLAYBAR.
