Hi Fred,
As long as your system hasn’t changed since the last time Airplay worked, it should still work the same. If the problem occurred after you updated to version 2.52, the problem can of course be due to the image. We will try Airplay again with a test device to rule this out. Has anything else changed on your iPhone? Do other services like Squeezelite work? And can you possibly test whether one of the Airplay plugins for the Squeezebox server works with your devices?
Edit: I have just successfully tested Airplay with v2.52. Can you make sure that no other services are running in parallel and that the sound card is not blocked? Which audio output did you choose for Shairport?
