Danny, my remote control volume buttons have failed on 5 separate devices. with one exception, all have the roku stick. The other is a Roku TV. I have refreshed the stick on each but still get no volume. Fortunately we have the tv remote device that will control the volume. Except for the TV, all have failed within a week of each other. I replaced batteries to no avail. I have ordered replacement units for the TV and just yesterday ordered one for one of the stick units.
My remote is doing the same thing. I have repaired both remotes, one in my living room and one in my bedroom to no avail. I find it funny that the only thing not working with BOTH of the remotes is the volume. Have you fixed this issue or have a work around.
Same issue just started today. I had to pair again, the go into the Roku setup and modify settings on an existing remote (voice) to control the TV and audio. The last two steps setting up the remote played music, then muted it.
Works like it has been for the last 18 months. Mute, +/- volume works again.
