How to Get Audio to output from a MacOS Device to a TV via HDMI

How to have audio from a video playing on your TV from a Mac output through the TV or sound device connected to the TV

Prerequisites: Familiarity with MacOS

Difficulty Level: Member • Nerd • Platypus

Estimated Time: 15 Minutes 

Expected Outcome: Have audio from a video playing on your TV from a Mac output through the TV or sound device connected to the TV

Tools Required: Macbook, HDMI Cable, TV with HDMI Input 

Steps to Perform 

1. Connect one end of the video cable (or an adapter, if necessary) to the computer’s Thunderbolt port , HDMI port, or DVI port , then connect the other end of the cable to the TV’s video input port.

2. If you need to adjust the resolution on your TV, choose Apple menu  > System Preferences, click Displays , then select Default for display to automatically use the best resolution, or select Scaled to manually select a resolution.

    

3. If you want your HDTV to play audio as well as video from your Mac, choose Apple menu > System Preferences, click Sound , then click Output.

    

   Select your HDTV in the list of devices. If you want to play audio on a different device (such as your computer’s speakers or an AV receiver that’s part of your sound system), select it instead.

   Note: If your Mac has a Mini DisplayPort , make sure you use a cable (and adapter, if necessary) that supports both audio and video.
