I am having trouble in using AirPlay on my iPad 2 after connecting it to speaker. In the first attempt, I set up AirPlay on my iPad and tried to connect the speaker through headphone jack. But, the AirPlay feature turns off when I plug in the speaker. I have tried to connect the speaker first and then enabled AirPlay. In this case, the sound won’t transfer to the projector. What are the procedures required to solve this?
