Set them up with the right ports.

Sometimes, your device disconnects from the soundbar. As I’ve mentioned earlier, they flashlight when they are waiting for any device for pairing.


Check if the soundbar is paired with your device through Bluetooth or not. If not, then pair them through Bluetooth.

If you can’t pair them through Bluetooth, then use a cable for this. It can happen if the soundbar is wireless.

Reason 3: Soundbar in Demo Mode
