Hi @Robert_Masters,
We understand this issue is taking longer to resolve than anyone would like, and we appreciate your patience. Our team still has an open investigation into the interaction between Airport Express devices and Apple’s RTSP protocol (AirPlay 1/2).
The core challenge is that Airport Express is a deprecated Apple device, but one that still functions otherwise within Apple’s contemporary network architecture. While its final firmware updates added cross-compatibility with AirPlay 1/2, that compatibility doesn’t always align with Roon’s own AirPlay 1/2 implementation. Since Apple is no longer updating the Airport Express’s Airplay stack at all, our developers must working on implementing workarounds and edge-case logic to accommodate the unique AirPlay behavior of this device. This is why progress is slower than we’d like.
We will provide more frequent updates in this thread as the ticket progresses. We’ll also let you know if any broader AirPlay fixes in Roon might impact this situation. Once we have a timeline for a fix that you can test, we’ll share it promptly.
Thank you for your patience and understanding.
