Check the volume level of the Bose system.
Be sure the system volume is not turned down. Using the volume control, gradually increase the volume level.
Turn up the volume of the connected device.
Set the device volume to 90–100% to send a strong signal to your product. Then, use your product to adjust the volume level.
If there is more than one Bose system on the network, be sure the correct one is selected.
In the Bose app, tap the My Bose icon ![\"icon\"]()
in upper-left corner to view the Bose products associated to your account. Tap the product you want to control to select it.
Switch sources from Bluetooth® to AUX, then back to Bluetooth.
Switching to AUX and then back will make the system reconnect to the Bluetooth device.
Reset your product.
Much like rebooting a smartphone, your product might need to be reset on occasion to correct minor issues. For more information, see Resetting your product.
Check for and install any available product updates.
For more info, see Checking the software or firmware version and Updating the software or firmware of your product.
If using an Amazon Echo Dot, clear the Dot memory of other Bluetooth® devices.
If the Dot disconnects from your product, it and your product both look for previously-connected devices to reconnect. This can result in the two products not finding each other. To prevent this, remove all devices except your Bose product from the paired device memory of the Dot: In the Amazon Alexa app, go to Settings > Alexa device > Bluetooth, then select and Forget other devices. Now, if the Dot disconnects, it will only try to reconnect your Bose product.
Restore the system to its factory defaults and restart the set up process.
For more info, see Resetting your product.
