A:AnswerThats optical for you, I had optical and suffered the same problem periodically. This sound bar sounds great with HDMI ARC cable connection. However, the problem could be the signal from the source you are getting it from. They sometimes send it like that from their end.
A:AnswerYes I’ve experienced this same type of interference.
You have to make sure that your subwoofer has a direct line of sight to your Vizio sound bar.
A:AnswerVizio has the same sound bar offered at a length of 30" instead of 24" - the V214x-K6. It's has the same height and its depth is 3.3", so this one is very likely the same.
A:AnswerVIZIO sound bars are designed to work with all TV makes and models, you just need a compatible audio connection! If the TV does not offer ARC, we would recommend using another audio connection type.
A:Answerit might be better to get a 5 speaker system , I have a Sony 5 speaker with digital tuner that i picked up open box price. it is truly spectacular surround sound for a smaller 14' x 10' room. I purchased this product for a mother's day gift so that my mother could feel the sound thru the sub-woofer as she is adjusting to senior citizen status with slight hearing loss.
