Today I check development build of kodi 16.8-002 (https://discourse.osmc.tv/t/testing-kodi-17-test-builds-for-raspberry-pi/11586).
I had also compiled Shairplay libraries on raspberry (https://github.com/juhovh/shairplay.git) and remove the old one from OSMC (/usr/lib/libshairplay*).
And AirPlay for sound is working on EL Capitan 10.11.1 (check with browser - youtube, and Tidal App for OS X).
