A:AnswerThis soundbar uses keyhole mounting. I tried to mount it to a wall mount sound bar mount, but it would not work because of little plastic feet meant to sit against the wall for support. I could never get the bracket to sit flush against the sound bar.
I then later returned it for other reasons.
A:AnswerHope you are not screwed but...
Mine did that same deal then the sound started shutting of every few minutes then dead. I got mine from bestbuy and it was just six months old when it died. it was in repair for over a month and was told they could not get the mainboard from sony finally they approved a exchange ticket and I got my money back
Good luck with yours

A:AnswerWhen you turn your cable box on, the soundbar should automatically select the right input if using arc. Also If you use the remote, you should be able to select the proper input without seeing the home screen. Atleast that is the way mine works.
