Change Audio Playback Devices - Mac

Body

Overview:

If you do not hear any audio coming from the classroom speakers it could be due to a wrong playback device selected. This article will show you how to change and test playback devices on a Mac.

 

Before you begin:

Connect an HDMI or VGA with audio cable to your PC.  If your MacBook does not have an HDMI port you will need to use a mini DisplayPort (Thunderbolt) or USB-C adapter depending on the model of MacBook.


Mini Display Port:

Uses a digital signal that carries audio and video over a single cable and does not require any additional cables. An adapter can be used to send the signal over HDMI or VGA (VGA requires the 1/8” aux cable for sound).
