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.

What sound output settings do you have your Samsung set to? Is it Dolby or PCM?

Hi, thanks for the reply. I just checked the settings and digital output is set to PCM. Dolby is greyed out and the only other option is DTS Neo 2:5.
Since I made this post I decided to plug the audio out from the Sky decoder to the soundbar and within an hour got the boom/thud sound. This has made me re-think that it can no longer be the Samsung TV causing the issue.

Cool - what is the sound output of your Sky box set to?
Have you tried a second cable?

Hi again, yep I tried an RCA cable and same issue. Sky box was set to Dolby when I used the optical cable

Try switching the Sky box to PCM, run with the optical cable and see if it improves.
If not, I'd focus solely on the soundbar.
