Unable to select or control Bose speaker as Chromecast speaker

In the Bose Music app, check the Chromecast Built-in feature is enabled for the speaker you would like to cast to. For more information, see Enabling or Disabling Chromecast Built-in. If there are multiple speakers in your Bose Music account, the feature would need to be enabled for each speaker. This feature is not available with Bose headphones; It is only available with network-connected speakers compatible with the Bose Music app.

Be sure to use an app that casts music and not video, such as YouTube Music Premium, Spotify, Pandora, TuneIn, iHeartRadio, or another Chromecast-enable music app. Only audio can be cast to Bose speakers; Video content cannot be cast.

If the app cannot find your product, see Bose app does not detect product.

The device you are using to initiate audio might be having trouble communicating on the network. Turn its Wi-Fi setting off and then on again to reestablish a network connection.

Exit the app casting to the Bose speaker. After waiting then reopening the app, determine if a Chromecast connection can be made in the same or other music app with Chromecast.

Try playing a preset or music service, or try controlling your speaker from the Bose app. If you cannot, the speaker is offline and needs to be reconnected to the network.

In the Bose app, go to the Technical Info screen from product's Settings menut and check its Wi-Fi Strength. The number will range from -30 dBm (best signal) to -90 dBm (poor signal). If the connection is poor, consider relocating the router and/or product or reducing sources of interference to improve signal. For more information, see Determining the Wi-Fi network name and signal strength of your product.

To use Chromecast, the device casting to the Bose speaker must be on the same network. For example, if the device is on the guest network and the system is on the main network, Chromecast will not work. Find the network name your are connected to within the Wi-Fi settings of your device, then determine if your Bose speaker is connected to the same network name. For more information, see Determining the Wi-Fi network name and signal strength of your product." If the two devices are on different networks, change the network of the device creating the Chromecast connection to match that of the Bose system.
