Samsung soundbar HWK450 keeps powering down.?

How do I stop my HWK450 soundbar to keep going off when it is set to BT (Bluetooth)? If the soundbar receives no audio for a period of time the soundbar keeps going off. I want to use it as an amplifier for my tablet and phones alarm clock but because no sound goes into the speaker throughout the night time the alarm clock audio does not go to my soundbar. I am not sure if it's the Bluetooth or if it's the power that keeps cutting off. I have contacted Samsung but they do not even know what to do. Do you have any ideas?

You can't. You would have to change the firmware, which is not possible. Use the aux input instead of BT, but remember that it will shut off after 8 hours with no signal.
