No audio from a Bluetooth® device

Make sure your device is connected to the speaker

Make sure the speaker is not muted and the volume is turned up. Set the Bluetooth device's volume to 90% and then use the Bose speaker volume controls to adjust the level

Try playing a different source on the Bluetooth device. For example, try a different app to determine if the issue is with a particular app

Your Bluetooth device may be out of range. Try moving it closer to the speaker

Move your Bluetooth device and/or the speaker away from other devices that generate electromagnetic interference (i.e. cordless phones, microwave ovens, wireless routers or other Bluetooth devices. If possible, turn off nearby Bluetooth devices or disable their Bluetooth functionality)

If you're hearing audio from a different Bluetooth device, pause audio on that device. For more information on using the system with two Bluetooth devices, see connecting to multiple Bluetooth devices

In the device's Bluetooth settings, choose to "FORGET" or "REMOVE" the Bose speaker. Then, pair the device to the speaker again and retest

On the speaker, press and hold the Bluetooth button for ten seconds until you hear a tone and “Bluetooth device list cleared,” if voice prompts are enabled

Reboot the Bluetooth device. This is typically done by shutting it down completely and then restarting it

Reset the Bose speaker by turning it on and holding the power button for 10 seconds until it turns off. Note: A factory reset clears the speaker's language setting and its paired mobile device memory, returning the speaker to original factory settings

Try a different Bluetooth device to determine if there is an issue with the device
