Setting up audio with your Horizontal Dock is a breeze! Just follow the instructions listed below if you are experiencing difficulty connecting to your audio device. 

First, dock your MacBook. Then go to System Preferences and click on the Audio icon, which will take you to your Audio Options screen. At the bottom of the screen, click the "Show volume in menu bar," as shown in the below picture.

The Audio icon should now be visible on the upper righthand portion of your screen. Hold down the "Option" button and click on the Audio icon. A drop down will appear with a few different options shown in the picture below.

You will see two options titled "USB audio CODEC." The first one is for the left port on the Horizontal Dock and the second option is for the right port. Select whichever side you are plugged into and you are all set!
