Your Android device and your Chromecast Audio or speakers that work with Google Cast will establish a direct connection when you cast your audio.
All devices running Android 8.0 or later (for Google Home app controls) support the Cast feature.
Note: Some Android devices may not have the necessary power to provide an optimized Cast experience.
Optimal performance
For optimal performance when you cast your Android audio, follow the steps below:
Step 1. Make sure your Android device and Chromecast Audio or speakers that work with Google Cast are both connected to the same wireless network name (SSID)
If connected via Wi-Fi, check that the network name displayed in your Chromecast Audio or Google Cast-enabled speaker settings is the same as the network your Android device is connected to.
Step 2. Make sure your Android device and Chromecast Audio or speakers that work with Cast are both connected to a Wi-Fi network with AP isolation disabled
AP isolation: Your Wi-Fi network configuration could prevent devices from communicating with Chromecast Audio or speaker with speaker that works with Cast. In order to resolve this issue, you'll need to disable AP (access point) isolation, also known as client isolation, on your router. Refer to your router documentation to learn how to disable AP isolation.
If you don't have access to your router settings, or if you attempt to connect through a guest, hotel or public network with AP or client isolation, you'll be unable to set up your Chromecast Audio or speaker that works with Cast.
Stuttering or poor quality
If you experience stuttering or poor quality when you cast your Android audio, follow the steps below:
-
The Android device and Chromecast Audio or speaker that works with Cast should be within 15 feet (4 meters) of each other. The Chromecast Audio or speaker that works with Cast should be 15 feet (4 meters) away from the router, or less.
-
Both your Chromecast Audio or speaker that works with Cast and Android device should be connected to the same Wi-Fi network channel, either 2.4 GHz or 5 GHz.
