Apple is releasing tvOS 26.4, a significant update for Apple TV that introduces a new 'Continuous Audio Connection' setting aimed at resolving long-standing audio issues for Sonos users. This feature maintains a Dolby MAT connection to ensure glitch-free playback across formats, especially addressing problems like crackling sounds and low volume levels when using Sonos speakers with AV receivers for 5.1-channel content. Beta testers report that enabling this setting fixes these issues, making 5.1 content sound as good as Atmos. The update also removes iTunes Movies and TV Shows apps, consolidating content into the Apple TV app. While the new setting improves audio stability, some users have noted it may cause issues with stereo sound. The update is currently in beta, with a full release expected soon. This enhancement is part of Apple's ongoing efforts to improve user experience for home theater setups.
