Disappearing 140 Pro Roon Endpoint / Non functioning Airplay

[David A]

Thank you, my understanding is Air does not work on Mac OSX Big Sur which is the latest Mac OS and running on my main machine

There are 2 "versions" or iterations of Devialet's AIR protocol. 

If you aren't using Roon then you have to run the Devialet AIR app on your computer and I suspect it does not work on the current Mac OS.

On the other hand if you're using Roon, and you have said that you are, you don't need to use Devialet's AIR app on your computer and, in fact, you should not use the Devialet app on your computer. Roon has actually incorporated Devialet's AIR code into the Roon software you run on your Mac. Because Roon runs on your Mac, it can use its internal implementation of the AIR protocol and stream to your Devialet using AIR. The Mac incompatibility lies with Devialet's own app. You don't need to use that if you're running Roon on your Mac because Roon does work on the Mac.

Not only do you not have to use the Devialet app if you're using Roon, if you do a search on this forum you will find multiple reports from forum members saying that Roon's internal implementation of the AIR protocol works better and more reliably than Devialet's own app does.

You can use Roon's internal implementation of AIR with both wifi and ethernet connections. Just connect both the computer you're running Roon on and also your Devialet to the same network, connect them via wifi or ethernet, it doesn't matter which one you use, and then you will be able to select your Devialet's AIR streaming input in Roon's Audio settings. Provided both computer and Devialet are connected to the same network it's as easy as falling off a log, a whole lot less painful than falling off a log, and you should definitely not run the Roon app on your Mac, in fact you should actually delete it. Roon is all you need to successfully make an AIR connection over either wifi or ethernet.
