To hear audio through the 3.5mm audio port on the Triple 4K Display Docking Station, change the sound output on your Mac to the dock's USB audio device.

1. Plug your 3.5mm headphones or speakers into the audio jack on the Triple 4K Display Docking Station.
2. On your Mac, open System Settings and select Sound, then Output.
3. Select "USB PnP Audio Device" or "General USB Audio Device".
4. If you are using a microphone, open the Input tab under Sound and select the same USB audio device.

The audio port on the Triple 4K Display Docking Station supports most 3.5mm headphones, speakers, and microphones.
