Actively exploited
Apple TV 4K lossless Dolby TrueHD playback achieved via open source workaround
Who is affected: Owners of the third-generation Apple TV 4K who want Blu-ray-quality lossless audio; scale not stated in the source.
An independent developer demonstrated a method to deliver Dolby TrueHD audio with Dolby Atmos effects to a home theater from the Apple TV 4K, which officially only supports the more compressed Dolby Digital Plus codec. The approach decodes TrueHD and Atmos positional data, then renders a fixed speaker layout (listed as 9.1.6) in a format the Apple TV 4K can output. The current method requires open source software and a Mac to set up, and the developer has proposed extending the Nuvio media player with it.
What to do: Wait for an official or app-based implementation before relying on it; do not attempt the manual Mac-based setup unless you understand the audio path described, since the source describes it as an elaborate workaround rather than a supported feature.
