Developer Finds Way to Play Lossless Dolby TrueHD on Apple TV 4K
A developer has devised a workaround that brings lossless Dolby TrueHD and Atmos soundtracks to the third-gen Apple TV 4K, with limits.
According to TechRadar, a developer has found a way to deliver lossless Dolby TrueHD movie soundtracks, including Dolby Atmos effects, to home theater speakers from the third-generation Apple TV 4K. The device officially supports only Dolby Digital Plus, a compressed format that streaming services use to limit data use. TrueHD, by contrast, is typically found on Blu-ray discs, where bandwidth is less of a concern.
TechRadar reports that the approach is not yet a finished feature for ordinary owners. For now, people who want to use it would need to build the feature themselves on a Mac. The outlet notes that an existing app, Native Player, delivers similar audio but is not open source. The developer's method has been proposed as an extension to the Nuvio media player.
The report describes the work as a clever hack, but the details available from the outlet are limited. It does not give a full account of how widely the method works across different titles, receivers or setups. Readers should treat the workaround as experimental until more independent testing is reported.
The story sits at the intersection of hardware limits and software creativity. Apple made a deliberate choice about which audio formats its streaming box supports, and this effort shows how enthusiasts can sometimes route around those choices.
Background
Audio on home theater systems is shaped by codecs, which are methods for encoding sound data. Some codecs are lossy, meaning they discard audio information to keep file sizes and data rates small. Dolby Digital Plus is one such format, widely used for streaming because it preserves good sound at a modest data cost. Lossless formats, such as Dolby TrueHD, keep the original recording intact, which is why they tend to appear on physical discs with generous storage capacity.
Dolby Atmos adds another layer. Instead of sending audio only to fixed channels, Atmos treats sounds as objects that can be positioned in three-dimensional space. Compatible speakers, including ceiling or height-mounted units, can place those sounds overhead. Atmos can be carried inside several underlying codecs, so the same immersive effect may arrive through different encoding paths depending on the source.
Streaming devices are usually designed around the content they expect to deliver. A box focused on subscription services has little reason to decode the heaviest lossless formats, and manufacturers often limit supported codecs to keep hardware simple and compatible. Enthusiasts, meanwhile, often want the best possible sound from the discs and files they already own. That tension between official support and user expectations has long shaped the home theater market, and it explains why workarounds appear whenever a gap opens between what a device supports and what listeners want.
Modern audio chains also involve passthrough, where a source device sends an encoded stream to an external receiver to decode. Whether a given format can pass through cleanly depends on the device, the cable, the receiver and the software handling the signal. Each link adds possible points of failure, which is part of why custom solutions tend to be fragile.
Why it matters
For people with capable home theaters, the story is a reminder that a streaming box's feature list is not always the final word on what the hardware can do. A working lossless path would mean higher-fidelity soundtracks for owners who value audio quality and already have compatible receivers and speakers. It also shows how much of the living-room experience now depends on software choices as much as physical equipment.
The development also raises practical questions about support and reliability. A feature that exists only in a self-built setup is not something most households can adopt. Users would need a Mac, technical comfort and patience with updates that could break the workaround. For anyone considering it, the gap between a clever demonstration and a dependable everyday tool is wide.
Finally, the story touches on the broader trend of open and third-party media players filling gaps left by platform makers. Projects like this can push manufacturers to reconsider what they support, but they can also create expectations that official products may not meet. The balance between device lock-in and user freedom remains a live tension in consumer electronics.
What to watch
Watch whether the developer's method becomes available in a more accessible form, such as a packaged extension rather than a DIY build. Pay attention to whether other players or community projects adopt the approach, and whether they reach a similar level of stability.
Also watch for any response from Apple, though the report does not indicate one. Any change to official codec support would be a notable shift. Finally, look for independent tests that confirm how well the audio works across a range of discs, receivers and speaker layouts.
Viewpoints
Commentary from our columns: three angles on this story.
The Builder the engineer's view
The interesting part of this project is not the headline but the plumbing. Getting a lossless bitstream through a streaming device that was never designed to hand it along is a problem of decoding paths, timing and output formatting, and each of those is easy to get almost right. A working demo on one Mac and one receiver says very little about how the thing behaves across a family of setups.
The fact that it is being proposed as an extension to an existing open media player is a good sign. Extensions can be tested, versioned and reverted, which matters when the underlying platform changes without warning. Native Player offers a comparable result, but without open source code, other developers cannot inspect how it works or fix edge cases.
If the builders want this to move beyond hobbyists, they will need clear documentation, reproducible test files and a way to report failures. Engineering credibility comes from showing the boring parts working reliably, not just from getting the flashy case to play once.
The User what changes for people who use it
For most people, the question is simple: will the movie sound better, and is it worth the trouble? Lossless audio can sound richer on a good system, especially when Atmos effects pass overhead, but only if the speakers, receiver and room are set up to take advantage of it. Many households will hear little difference from the streaming version they already watch.
The bigger change for users is the effort. Building the feature on a Mac is a hobbyist task, not something to hand to a relative who just wants the film to start. Anyone who tries it should expect to troubleshoot audio dropouts, mismatched settings and updates that may break the setup.
Still, the story offers a useful reminder. Owners of a physical Blu-ray collection may find that the sound they paid for is not always the sound their streaming box can deliver. Knowing what your equipment can actually decode is the first step toward getting the experience you want, and that knowledge is worth having before you start tinkering.
The Skeptic open questions and weak points
Before celebrating, it is worth asking what has been shown and what has not. The report describes a clever hack, yet the available details are thin on how consistently it works across discs, receivers and speaker layouts. A method that succeeds in a demonstration can fail quietly on the next firmware update or with a different source file.
There is also a question about how much of this is truly new. Native Player already reportedly delivers similar audio, which suggests the underlying capability has been reachable for some users, though through a closed product. The proposed extension may be an improvement in openness, but whether it is a meaningful technical leap is not yet clear from what has been reported.
Finally, readers should be cautious about the gap between a feature that exists and one that is supported. Apple has not, according to the report, changed its official list of formats. Until independent testers confirm the results, the most accurate description is promising but unverified.
