A:AnswerThat probably would work fine, but the manual does say that the best placement is below your television. I put mine above because I don’t have room below and it sounds great.
A:AnswerThe sound bar came with brackets to mount on a wall, but you might be able to adapt them to your TV. I did not mount the sound bar. I placed it on a shelf above my television.
A:AnswerYes it is compatible but you will likely need to enable ARC/eARC or select the correct audio output on the TV’s settings once — the TV doesn’t always switch audio automatically.
A:AnswerYes it has an option for Digital Optical input.
Connect an optical (TOSLINK) cable from your TV’s Optical Out to the soundbar’s Optical In.
Select “Optical” as the audio input on the soundbar.
On your TV, set the audio output to Optical (may be called “Digital Audio Out”).
A:AnswerIf you switch to the TV's speakers does this still happen? If so it, it could be a buffering problem or a source problem. Too many variables to answer here.
