I see this advertised in the presentation sections of Sonos One SL: “Use a pair as rear home theatre surrounds with Playbar, Playbase, or Beam.“.
I get how it works theoretically.
What I’m worried about is: the sound comes from the TV to the Beam through HDMI, but then from the Beam to the OneSL rear speakers through Wi-fi. Because of this, isn’t there some (very small, but still...) delay ?
IMO, there’s no way a wi-fi connection can be as fast as the cabled one. And if there would be a delay, there’s nothing the Beam can do through software, as it doesn’t receive the sound any sooner that the moment when the TV outputs it…
Who has set up and is using such a configuration ?
What can you tell me, am I worried for nothing ? Is this really working ok, without any delay issues ?

To minimize this possible delay front the Beam to the surrounds Sonos utilises a dedicated 5Ghz link between Beam and surrounds. I have a set up that consists of a Beam, two One's (ad a Sub) in the front room and have not noticed any lag from front to back. Not on surround (but the nature of surround - ambient- sound means lag would be less noticable), nor on music (where you would notice lag or sync problems sooner).
