We just bought a Vizio soundbar VSB200. Is it me or do they not explain in manual how to use the thing? The little lights blink on or off in the corner but what the heck do they mean? Is the sound suppose to come out of the soundbar itself or the speakers on TV now? How do I know it's in the correct input? Do I have to turn it on & off everytime I watch TV? All I want is to watch TV without the sound going too high or too low as it does on the TV speakers alone. Is the soundbar even worth the trouble?!
