Ok, so I'm working in a new classroom with the following scenario I'm trying to solve. I have a MacBook Air connected to a ceiling projector using AirPlay. The thing I don't like with this is that the audio also plays out of the builtin speakers within the ceiling projector. The speakers are quiet and just bad sounding. I have a set of good computer speakers that I'd like to simply connect to my MacBook, but the audio automatically goes to the projector. Is there any way to bypass this?
