I’ve been having issues streaming audio from my mac to my Pi2 via Airplay/iTunes over wifi, playback is unreliable and choppy a lot of the time. I don’t think it’s a network issue, the machines and the router are only a couple of meters apart, and in the same room. I’m thinking maybe it’s a cache issue? Not sure. This has been driving me nuts for a while, any help would be much appreciated!
Might be worth tryping buffermode=1 from http://kodi.wiki/view/HOW-TO%3AModify_the_video_cache
