My friend has a Vizio TV and Vizio soundbar. She has not used the soundbar since she got it. It was just too much trouble since she had to get up and go to it to mute it or turn the volume up or down and on and off. Big PITA. I tried stepping her thru the settings because her manual said the TV remote would also work the soundbar. We did it and it did not work. So, I bought her a remote specifically for her soundbar, Vizio remote, not universal. It did not work either. This Firmware update fixed the remote problem. VIZIO Support If your model number is different search for it. Same with the Brand , etc. Not only did it fix the problem, we set the soundbar to let the original TV remote operate the soundbar. It works now also. Since her Dish Networks remote was programmed to operate the sound on her Vizio TV it also now operates the soundbar. So, now we have 3 remotes that work the soundbar. Who would have thought that a soundbar would need a Firmware update ?
