tvOS 26.4 fixes an annoying audio issue on Apple TV 4K

Apple has officially released tvOS 26.4 for Apple TV 4K, and while the update brings a handful of new features to the popular streaming device, it is a critical audio fix that has users breathing a sigh of relief. The update is available now and can be downloaded directly from the Settings app on any compatible Apple TV 4K model. Apple has encouraged all users to update as soon as possible to take advantage of the improvements.

For weeks, Apple TV 4K owners had been reporting a frustrating audio bug that caused intermittent sound dropouts and sync issues during playback. The problem appeared to affect a wide range of content, from streaming apps like Netflix and Disney Plus to Apple's own TV app, and was particularly noticeable when using HomePod speakers or soundbars connected via HDMI ARC and eARC. Users flooded online forums and social media with complaints, and Apple eventually acknowledged the issue, promising a fix in an upcoming software update.

With tvOS 26.4, Apple says the audio problem has been fully resolved. According to the release notes, the update addresses a bug that could cause audio to cut out or fall out of sync with video under certain output configurations. Early reports from users who have installed the update suggest the fix is working as intended, with smooth and reliable audio playback restored across all major streaming platforms and audio setups.

Beyond the audio fix, tvOS 26.4 also introduces several new features designed to enhance the overall Apple TV experience. These include improvements to the user interface, enhanced Siri integration for more natural voice commands, and expanded support for third-party smart home accessories through the Home app. Performance optimizations round out the update, making navigation and app launching feel snappier. Apple TV 4K owners can install tvOS 26.4 by navigating to Settings, then System, and selecting Software Update.
