Solved! RCA sound bar

Rca sound bar stopped working on HD channels

HD Channels? Model of the sound bar? Did you try and connect it to another television and seen if the issue persists?

It is a 37 in rca .. works on my tv except HD channels

So this used to work? Maybe HD channels are outputting surround which this SB cannot handle, must tell TV to downsample surround?
