I read the manual at http://downloadcenter.samsung.com/content/UM/201403/20140320101947640/HW-H570-ZA-ENG-IB_cms.pdf for the sound bar and it looks like the sound bar remote can turn on and operate the TV so I can't guess why I would have more than one remote.
With that "Auto Power" button and the TV power button it seems like it would all turn on.
I have a un65h7150 with an HW-H570 sound bar. right now it is connected via an optical cable so it will turn on automatically. I have the tv speakers off. and I'm controlling the volume with the sound bar remote
Is there anyway I can make the tv remote or even my cable remote control the volume? I bought a Samsung sound bar so I didn't need two remotes. now I seem stuck using two remotes.
I'm also going to buy a Samsung blu ray player. I hope I don't end up with three remotes.
