Does anyone know why this would be happening ... it happens on any channel we watch...
Tried Roku directly into tv works fine but sound bar was not connected.
Not sure how to connect Vizio Tv to Samsung sound bar while Roku stick connected to TV???
BTW, Roku stick directly in sound bar has been working fine until about a week or two ago then we experienced white static on tv!! What gives...
You've eliminated tge Roku as the cause of the problem. So now you need to take your questions abiut the sound bar to Samsung.
