[RSB-14 constant hissing]

Still no response!!??

[RSB-14 constant hissing]

Hello, I have seen quite a few people post this issue but have seen no one respond about the issue to get fixed 

I own the rsb-14 soundbar with sub. There is a constant static noise, hissing sound coming from the 2 outside speakers of the bar. I contacted the dealer and got a new replacement soundbar. Yet still the issue persists?? Any reasons as to why? 

It happens through the optical and the hdmi-arc input. And the power source in plugged into monster power, power source.
