tvOS 27 Is About to Transform Your Living Room Audio Experience
For years, audiophiles and Apple Music subscribers have enjoyed the benefits of lossless audio on their iPhones, iPads, and Macs — but the Apple TV 4K has quietly lagged behind. That changes with tvOS 27. Apple has officially announced that its next major television operating system update will bring full Hi-Res Lossless Audio support to Apple Music on the Apple TV 4K, elevating the home listening experience to studio-quality levels. Whether you're a casual listener or a dedicated audiophile, this is one of the most significant audio upgrades Apple has delivered to the living room in recent memory.
What Is Hi-Res Lossless Audio and Why Does It Matter?
Before diving into what's changing in tvOS 27, it helps to understand the difference between standard audio formats and lossless audio — and specifically what "Hi-Res" means in this context.
Lossless audio refers to a form of digital compression that preserves every single piece of the original audio data. Unlike formats such as MP3 or AAC, which discard certain audio information to reduce file size, lossless audio keeps the full waveform intact. This means what you hear is far closer to what the artist and sound engineer intended when they recorded the track in the studio.
Hi-Res Lossless takes this a step further. Where standard Lossless audio on Apple Music tops out at 24-bit/48 kHz, Hi-Res Lossless reaches up to 24-bit/192 kHz — a significantly higher sampling rate that captures more detail, more nuance, and more of the acoustic texture of a recording. For reference, standard CD-quality audio sits at 16-bit/44.1 kHz, meaning Hi-Res Lossless delivers considerably more audio data per second.
Whether the human ear can fully distinguish Hi-Res Lossless from standard Lossless in every listening scenario is a topic of ongoing debate among audio engineers and enthusiasts. However, on a high-quality speaker system connected to an Apple TV 4K, the potential difference becomes far more meaningful — and that is exactly the use case tvOS 27 is targeting.
What Apple TV 4K Supports Today (tvOS 26)
As of tvOS 26, Apple TV 4K already supports Apple Music Lossless audio — but only up to 24-bit/48 kHz. While this is a step above standard compressed audio, it falls short of the Hi-Res Lossless tier that many Apple Music subscribers may already have access to on their other Apple devices. Hi-Res Lossless playback, which requires audio above 48 kHz (and up to 24-bit/192 kHz), has simply not been available on the Apple TV 4K until now.
This gap has been a frustration for users who have invested in premium home theater speaker systems and expect their Apple TV to serve as the centerpiece of a high-fidelity audio setup. With tvOS 27, Apple is closing that gap in a meaningful way.
What's New in tvOS 27: Full Hi-Res Lossless Audio Support
With the release of tvOS 27, Apple Music subscribers will be able to stream Hi-Res Lossless Audio directly through their Apple TV 4K — provided they have compatible external speaker outputs connected. Apple has confirmed that users with the right audio hardware will be able to enjoy their favorite songs in the highest available audio quality, experiencing what the company describes as studio-quality sound delivered directly through the Apple TV 4K.
This is a landmark upgrade for the platform. Key highlights of the tvOS 27 audio update include:
- Support for Hi-Res Lossless Audio on Apple Music, going beyond the previous 24-bit/48 kHz ceiling.
- Playback capability of up to 24-bit/192 kHz, matching the highest tier offered by Apple Music across its entire ecosystem.
- Compatibility requires external speaker outputs — users relying solely on a connected TV's built-in speakers may not benefit from the full upgrade.
- Available to all Apple Music subscribers at no additional cost, as Hi-Res Lossless is already included in the standard Apple Music subscription.
How to Try It Now: The tvOS 27 Developer Beta
Apple has already seeded the tvOS 27 developer beta, meaning registered Apple developers can access the update today and begin testing the new Hi-Res Lossless Audio functionality. If you're a developer and want to get early access, you can install the beta through your Apple TV by navigating to Settings → System → Software Update → Beta Updates on a supported Apple TV device.
It is worth noting that developer betas are pre-release software and may contain bugs or instabilities. For most users, the recommended approach is to wait for the general release. Apple is expected to roll out tvOS 27 to the public in the fall, in line with its typical annual software release schedule.
What You'll Need to Take Full Advantage
To get the most out of Apple Music's Hi-Res Lossless Audio on tvOS 27, your setup matters. Here's what to keep in mind:
- Apple TV 4K: You'll need a compatible Apple TV 4K model running tvOS 27. Older Apple TV HD models are not supported for tvOS 27.
- External audio output: A compatible external speaker system connected via HDMI ARC, HDMI eARC, or optical audio is recommended to take full advantage of the higher resolution audio stream. eARC in particular offers the bandwidth needed for high-resolution uncompressed audio.
- Apple Music subscription: Hi-Res Lossless Audio is included with all Apple Music plans at no extra charge. Simply ensure Lossless Audio is enabled in your Apple Music settings.
- A quality listening environment: High-resolution audio shines most in a well-treated acoustic space with quality speakers or a premium soundbar capable of resolving fine audio detail.
The Bigger Picture: Apple's Commitment to Audio Quality
Apple's decision to extend Hi-Res Lossless Audio to the Apple TV 4K with tvOS 27 is part of a broader push toward premium audio across its product ecosystem. Since introducing Lossless and Hi-Res Lossless Audio to Apple Music in 2021, the company has steadily worked to bring those capabilities to more devices and more listening scenarios.
Bringing Hi-Res Lossless to the living room is a logical and long-overdue next step. The Apple TV 4K is increasingly positioned as a hub for premium home entertainment, and audio quality is a core part of that experience. Competing streaming services and dedicated hi-fi streaming platforms have offered high-resolution audio to home theater setups for some time — with tvOS 27, Apple is making a clear statement that it intends to match and surpass those offerings for its subscribers.
Final Thoughts
tvOS 27 represents a genuine and exciting upgrade for anyone who takes home audio seriously. By bringing Hi-Res Lossless Audio up to 24-bit/192 kHz to Apple Music on the Apple TV 4K, Apple is delivering on a long-standing request from audiophiles and enthusiastic listeners alike. Paired with a capable external speaker system, the Apple TV 4K is poised to become one of the most compelling hi-fi streaming sources available for Apple Music subscribers.
