Hello @experienceslb ,
Thank you for reaching out.
The Sound United team is working on a Marantz RAAT SDK integration and their early, uncertified RAAT SDK code made it into a public release. We don’t have a timeline on when a release will happen.
You were very likely using Airplay or another input to stream to this device previously, and until your device is fully certified, I would suggest reverting to the previous input method you were using.
