Hi Andreas and Bill,
Thanks for your requests. We use shairport both in our Audioplayer plugin and in the newly added MultiShairport plugin. We just tested our current shairport client with a current iOS device and did not encounter any issues. We could play several songs continuously without interruptions or having to click play again. You can also still use the shairtunes2 plugin for the LMS which turns all your squeezelite players into airplay players. We will look into the possibility of including shairport-sync in a future update. If you found wrong documentation stating that we already use shairport-sync, please point us toward these mistakes and we will fix them.
