Q:
How do I play sound through the projector?

If you are projecting from a computer or video device using an HDMI or USB connection, you do not need to connect a separate audio cable to hear sound.

Note: Older Macs may not support audio over HDMI and a separate audio cable must be connected to obtain sound.
