A:Answer Doesn't sound like it's the bar. Sounds like the signal what we're you watching on what? Was it cable , satellite, HD, maybe HD, Internet,?
I've personally heard a difference on none HD channels, and some providers say it's HD and it's not , and some times the dolby signal on Internet stuff gets lost. If you were watching a DVD player something is wrong, but depending on where your putting the optical cable, I have mine right from the TV so anything playing comes through no matter what uniit I'm using , chrome cast, cable , DVD, games
