About this app

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.

What’s new

Die optionale Bedienungshilfen-Funktion für Lautstärketasten ist jetzt schon bei der Lautsprechersuche erreichbar – auch ohne gefundenes Sonos-Gerät. Vor dem Öffnen der Android-Einstellungen zeigt SonosCast eine klare Offenlegung zu Zweck, Datenzugriff, Nicht-Speicherung, Nicht-Weitergabe und Optionalität mit separater Zustimmung oder Ablehnung.
