I have a Sony 4K TV with a Sony Sound Bar and a UHD YV box. I currently have my TV sound turned off, with the TV option set to output to the Sound Bar. I currently need to use 3 remotes, one for the TV, one for the Sound Bar and the YV one. I would really like to rationalise these and if possible would just want to use the YV one. I have followed the instructions to programme the YV remote to control the TV and it only partially works. I can now turn the TV on and off with the YV remote, but the volume + and - is trying to control the TV sound, not the Sound Bar. Also, the TV AV button doesn't cycle through all the TV input options. Any help gratefully received as my sofa is rather cluttered at the moment! Many thanks.
