Best answer: Unfortunately, the Apple TV 4K doesn't include native support for optical audio. Your best bet is to use an audio extractor, and since you're using an Apple TV 4K, you'll want one that supports 4K video.

Amazon: ViewHD 4K HDMI Audio Extractor ($43)

An audio extractor can add optical audio support without the bulk of an A/V receiver

Those who relied on the optical audio port to hook up your AV system will be disappointed to find that the Apple TV 4K doesn't include that optical audio port. Luckily, you can get around that with an HDMI-to-Toslink (optical audio) extractor.

If you already have an audio setup in your home that includes an A/V receiver with optical audio support, you should, of course, use that. But for most people, VewHD's 4K HDMI Audio Extractor will do just fine. It features optical audio support without the large footprint of most receivers.

You just plug your Apple TV 4K into the extractor with a 4K-capable HDMI cable, then use another HDMI cable to plug the extractor into your TV. Connect your optical audio speakers to the extractor, make sure everything's plugged in, and you're ready to go.

Are there any issues with video quality?

Because you plug your Apple TV 4K into the ViewHD extractor rather than directly into your TV, you might be worried about a loss of video quality, but you don't have to. The extractor supports 4K video output at up to 60Hz, more than enough for 4K movies and TV as long as you have the right HDMI cables.

Additionally, the ViewHD extractor supports high dynamic range video. Both the HDR10 and Dolby Vision HDR formats are supported through this extractor, letting you take advantage of their increased color depth and quality.

Don't break the bank

Some audio extractors can cost hundreds of dollars. The ViewHD extractor costs only around $43, so your wallet will thank you.
