Audio Out To An HDMI Projector

Metcalf School has some awesome projectors that work well through HDMI connections. In addition to video capability, HDMI is nice because it can also carry audio to the projector's speakers. Recently, teachers have asked how to get the audio playing from their Macbook's somewhat diminutive speakers to play on the projector speakers. Macbooks are not smart enough to know that you automatically want to play through the projector's speakers, so you have to tell your Macbook to play the audio through the projector. The video below shows how to make a sound choice.  ;-)
