Change  Audio Playback Devices – Windows


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 Windows.


Before you begin:

Connect an HDMI or VGA with audio cable to your PC.

HDMI – Uses a digital signal that carries audio and video over cable and does not require any additional cables.

VGA - Uses an analog signal that only carries video, it does not carry audio. VGA requires an additional 1/8” aux cable to be plugged into the headphone jack for sound to be played through the system.
