The Playbar itself does not, but if a Sonos One or a Sonos Play:5 Gen2 is in the same group, you can use AirPlay 2.

In my opinion, the Playbar alone makes little sense anyway.
With the Sonos Sub and two Sonos One, you have an excellent home cinema for the living room.
In the bedroom, where I don't need surround, I have a Sonos Beam, which is AirPlay 2 capable.
