the audio line-out connector of the device and the audio line-in connector of the
computer.

stereo speakers (speakers with built-in amplifiers), headphones, multimedia
keyboards, or the audio line-in connector on a stereo system or other external
recording device.
DisplayPort connector

that use a DisplayPort connector.
