A:AnswerI don't have/use a llive sound bar, but I couldn't get it to work with my TV and cable box, so for me it turned out to be a total waste of money.
A:AnswerThis remote comes with programming codes for the device you are using it with. Just look up the code and go from there. YouTube videos for this remote make programming it very easy compared to the poor instructions that come with it.
A:AnswerYes, it will. Just enter the proper programing code in the users manual. If you have trouble, go to YouTube, videos there make programming way easier than the poorly written instructions.
