I have three Samsung TVs with Roku sticks. On the same day, all three TV remote volume and mute buttons started to work intermittently. At first I thought it was one bad remote, but the problem occurs on ALL TVs and their respective remotes. The buttons will work a few times, then stop. If I fiddle with the remote (change channels, pause, etc.) or wait a few minutes, the functions return. I have re-set the Rokus, re-paired them, and replaced batteries but the problem persists. I have been using these Rokus for over a year and the problem just appeared out of the blue. What gives? Quite a coincidence that the problem occurred on all TVs on the same day.
