Kanex Digital Audio Adapter for Apple TV 4

The Digital Audio Adapter features an optical audio and HDMI output, as well as a 3.5mm jack for external speakers. This allows you to play your favorite music, podcasts, TV shows, or radio channels through your Apple TV 4. You don't have to worry about the sound, as your existing stereo system or surround system can easily be connected to the adapter or the Apple TV 4 via the 3.5mm jack.
