Hi, I purchased the Klipsch SB 1 sound bar and sub in August 2013. In the past three weeks approx every hour/ 2 hours the sub is making a boom sound. The boom is just a split second. I'm using a 55" F6400 Smart Interaction 3D Full HD LED TV. I am now convinced it's a Samsung TV issue. I connected the a Sony TV to the sound bar, via optical cable. 3 hours and not one thud/boom. Within 10 mins of reconnecting Samsung 2 booms. Looks like the firmware has done something to the external speaker setup. Its the same sound if you turn an amp off and you get the bang through the speakers. This all coincides with a Samsung firmware update 3 weeks ago.
Has anyone else had subwoofer/soundbar issues since recent firmware updates to their Samsung LED Tv's.
