The Frustrating Audio Glitches Between Apple TV and Sonos Are Finally Getting Crushed – Thanks to One Smart New Setting
If you've ever sunk into your couch for movie night, remote in hand, only to have your Sonos sound system suddenly crackle, drop volume levels out of nowhere, or produce weird popping noises right when the action ramps up, you're not alone. For years, users pairing Apple TV (especially the 4K models) with Sonos speakers—often through an AV receiver or directly via HDMI eARC—have battled inconsistent audio performance. The culprit? Abrupt switches between audio formats like 5.1-channel PCM and Dolby Atmos, which force the system to renegotiate the connection mid-stream, leading to those infuriating interruptions.
The good news hit in February 2026: Apple quietly introduced a game-changing fix in the tvOS 26.4 public beta. It's a simple toggle called “Continuous Audio Connection”, and early testers are calling it a lifesaver for home theater setups heavy on Sonos gear.
What Was Breaking the Magic?
Picture this: You're watching a standard TV show or older movie streamed in 5.1 PCM (the uncompressed, multi-channel format many services default to). Everything sounds fine. Then you switch to a Dolby Atmos blockbuster on Apple TV+, Netflix, or Disney+. Boom—your Sonos Arc, Beam, or full surround setup glitches. Users reported:
Sudden volume drops, making dialogue whisper-quiet compared to explosive effects.
Crackling or popping sounds during format handshakes.
Uneven channel output, like missing center-channel clarity for voices.
Occasional full dropouts or clipping at scene changes, pauses, or even app switches.
These weren't isolated complaints. Forums like the Sonos subreddit and Apple Communities lit up with threads from frustrated owners, some even troubleshooting HDMI cables, firmware updates, or workarounds like forcing Dolby Digital output or disabling eARC on their TVs. The root issue stemmed from how Apple TV handled dynamic format changes: it would briefly sever and re-establish the audio pipeline, and Sonos hardware (particularly when paired with certain AV receivers) didn't always recover gracefully.
Enter “Continuous Audio Connection” – The Persistent Stream Solution
Apple's fix is elegantly straightforward. When you enable Continuous Audio Connection in your Apple TV's audio settings (under Video and Audio > Audio Format or similar), the device locks into a Dolby MAT (Metadata-enhanced Audio Transmission) connection. This keeps a steady, always-on audio stream flowing, even when the content itself switches formats.
Apple describes it perfectly: the setting ensures “glitch-free playback across formats”. No more renegotiations mid-playback. The audio pipe stays open, Dolby MAT carries the metadata for Atmos when needed, but older receivers might just show an “Atmos” indicator without altering the original mix.
Beta testers on the Sonos subreddit wasted no time confirming the win:
One user said their 5.1 PCM content now matches Atmos levels perfectly—no more “way quieter” complaints.
Another reported zero dropouts, pops, or volume inconsistencies in mixed-content sessions.
Multiple people with Sonos Arc Ultra, Beam Gen 2, or full surround setups paired with projectors or TVs declared the issues “fixed just like that.”
It's especially relieving for those who invested in premium Sonos home theater ecosystems expecting seamless integration with Apple's ecosystem. The feature directly targets the pain points that made some users question their setup choices.
Any Caveats or New Quirks?
Like any beta feature, it's not flawless for everyone yet. A few early reports noted:
Surround speakers occasionally going silent if the setting interacts oddly with upmixing on certain Sonos configs.
Sonos apps sometimes displaying everything as “Dolby Atmos” (even stereo or 5.1 content), though it's just metadata labeling—the actual playback remains true to the source, and no upmixing occurs unless intended.
These seem minor and fixable, with full release expected in late March or early April 2026. Apple also bundled other tweaks in tvOS 26.4, like removing legacy iTunes apps from the home screen, but the audio upgrade is stealing the spotlight.
Why This Matters for Your Setup
If your living room revolves around an Apple TV feeding a Sonos soundbar or multi-room system, this update could transform your experience from “good but glitchy” to reliably cinematic. No more pausing to fiddle with settings, no more wincing at random audio artifacts during key scenes.
Want to try it now? Head to the Apple TV public beta program (via Settings > System > Software Updates > Beta Updates) and install tvOS 26.4. Toggle on Continuous Audio Connection, queue up some mixed-format content, and listen for yourself. Many are already reporting night-and-day improvements.
Apple and Sonos have had a rocky but evolving partnership—think AirPlay support, Trueplay tuning, and now this targeted fix. This small setting shows both companies listening to real-world feedback. For audiophiles and casual binge-watchers alike, it's proof that sometimes the biggest upgrades come in the simplest packages.
Your immersive soundstage just got a whole lot smoother. Grab that beta, flip the switch, and enjoy the silence... of no more audio complaints.
