AirPlay malfunctioning (image and sound delay)

Hu everyone, I am experiencing problems with Airplay mirroring from a Macbook. Specifically, image would sometimes become jerky and more often there is a clear delay between image and sound (with sound being late), even if I connect the projector to speakers via cable. This is happening with any video I would play from the Macbook (youtube, amazon video, netflix, other streaming videos). Internet connection is sound at home. Any suggestion? @PhilipsEngineering @PhilipsNono or anyone else?
Thank You
