How’s this for technical? No.
Unfortunately, they’re essentially incompatible systems.
Thanks. And not able to sync with AirPlay?
Not really sure what you’re asking.
Currently, AirPlay 2 can only send a stereo signal to a Sonos.
The PLAYBAR was designed and manufactured before Sonos supported AirPlay 2. It can not receive an AirPlay 2 signal. It can be grouped with an AirPlay 2 target, though. I used to do this frequently, with my PLAYBAR setup and a Sonos One.
I’ve never attempted to use the bandwidth to send more than one AirPlay 2 stream, but I’m not aware that Apple guaranties the synchronicity between multiple streams, that’s something you’d need to check with Apple. I do know there is no way to split the audio in one AirPlay 2 stream and a video stream…I tried that just yesterday, again, to see if anything had changed in iOS 18.2 It has not.
Essentially, the HomePod stands as one system, the Sonos as another.
