No, unfortunately you cannot “feed” anything to AirPlay 2. Playback must start from an iDevice.

You can of course multiroom it via NL, but then you can only use B&O speakers. Not generic AP2-speakers.

Understood. Thanks

so no workaround?

Kludge workaround: Repurpose an ancient Mac computer to the task.  

Rogue Amoeba makes an application called "Airfoil" which can redirect any "Audio Device" to any combination of Airplay and Airplay2 speakers.  Take the Powerlink output of the 9000, route it to the Line In jack of the (old, remember, they have a line in jack!?!) Mac, and set Airfoil to send that to whatever Airplay device.  (Airfoil "Audio Device" also includes Mac OS programs, but we're not interested in that, even though it's the main point of the product!)

Download it for free first, from rogueamoeba.com, just to make sure it runs on your Mac, your old OS, and actually works with the Line In jack.

Edit: Of course, this *completely misses* what makes the integrated B&O system so good: You cannot "join" from other speakers, nor can you control the 9000 via the TV or anywhere else other than its own IR receiver (and panel/edge buttons of course).  You can't wander into another room with another TV and press "Link CD", none-o'-that.  Also changing the speaker groups is a hassle if you have to remote-control your Mac with an app to get Airfoil to swap speakers.

(Generally speaking, Apple was only licensing Airplay *output* devices, and you needed an Apple device to act as source device.  That's the case for this workaround too.  Hopefully this will change sometime soon, with manufacturers being allowed to act as a source as well as a destination.  But not today.)

Thanks, trackbeo, that’s really helpful

What I dont get, is why there's no substitute!?

Airplay is an Apple patend, but if I understand well "music over wifi" is not: NL, Sonos, maybe others?

Why isn't there somewhere around little magic boxes which TX and RX music over a network?

Because Apple does not want it to be.

Or because noone has - untill now - knacked the codes to make such a product possible (which I guess at the moment would be illegal).
