| LED status | LED indicator meaning |
| Solid white | Chromecast Audio is connected to the network and is ready to begin casting content, or is already casting content. |
| Pulsing white | Your Chromecast Audio is disconnected and needs to be set up. |
| Pulsing orange | Your Chromecast Audio is receiving an update and is not available for casting. It will be available for use shortly. Don't disconnect your device from power. |
| Solid orange | There may be an error with your device. Perform a reboot on your device by unplugging it from the power source, waiting about 1 minute, and then plugging it back in. If that doesn’t resolve the issue, try a factory reset. |
