A:AnswerCheck woofer volume on remote. I had same issue and was pressing woofer button in. Here turns out it must be pressed up or down. Watch sound bar and volume numbers will be displayed.
A:AnswerIf the soundbar is turning on when the TV is powered on it should also power off as well. Check your TV options. If that doesn't work it might be a defected soundbar or you are using the other options such as Bluetooth to another device. If that's the case if you turn off the TV then the soundbar will stay on.
A:AnswerI had the bass at 6 because from what I experienced the bass isn't all that powerful unfortunately, and I had the treble at 4 or 5 depending whatI was watching. I would play with it though. Audio I had 300.
A:AnswerFirst the obvious is to turn the subwoofer volume down. Next, elevate it and put it on something made of a thick rubber. That will isolate some of the louder bass signal.
A:AnswerIt works with Samsung. Check model numbers, bring info to best buy they should be able to tell you what will sync. A 4k ultra is the latest version of TV so i would say most likely this sound bar would work. Always check with associate.
