SonosCast

Stream supported audio from your Android device to a compatible Sonos speaker on the same Wi-Fi network. SonosCast works directly inside your local network — with no account, ads, or tracking. HOW IT WORKS 1. Connect your phone and speaker to the same Wi-Fi network. 2. Open SonosCast and select a discovered speaker. 3. Start casting and approve Android's audio-capture prompt. 4. Play audio in an app that permits Android audio capture. CONTROLS • Adjust the speaker volume directly in SonosCast. • Stop casting in the app at any time. If Android is allowed to show the notification, pause and stop actions are also available there. • Optionally, the phone's volume buttons can control the selected speaker during an active cast. This requires separate activation of the Android Accessibility Service and is off by default. LOCAL AND DATA-MINIMIZING • No user account or sign-in. • No advertising, analytics, or tracking SDKs. • No audio upload to the developer and no cloud relay. • The audio stream is processed temporarily in memory and is not saved as a file. • Phone-to-speaker communication stays inside the local network. REQUIREMENTS • Android 10 or newer. • Phone and a compatible Sonos speaker on the same Wi-Fi network. • The network must allow direct device connections and speaker discovery. Guest Wi-Fi, access-point isolation, or separate VLANs may prevent connection. IMPORTANT LIMITATIONS Android does not allow universal capture of all device audio. Apps can block capture of their playback. DRM-protected content, calls, notification and alarm sounds, and other audio sources that do not permit capture may therefore remain silent. Wi-Fi and speaker buffering create an audible delay. SonosCast is not intended for lip-synced video, live performance, or musical instruments. The optional volume-button control uses Android's Accessibility Service only to forward volume-up and volume-down button presses to the selected speaker during an active cast. SonosCast does not read screen or text content and does not store or share key data. Sonos is a trademark of Sonos, Inc.
