Roku "voice" remote will not work volume and mute with Vizio sound bar.
Both of my TVs are newer model Roku, they both have the same model Vizio sound bar on them. The remotes that came with the TVs will work with the learning function of the Vizio sound bar to control volume and mute. However when I purchase Roku voice remotes I cannot get them to work with the vizio's learn function with volume up down and mute. I have tried different voice remotes but none of them will work with the Vizio sound bars learn function. The sound bars are older model vizios and do not have HDMI, and are connected by a optical. I don't understand why the remotes that came with the TV will work, but voice remotes will not.
