I Need help. My roku remote is not working. I’ve changed batteries and all. I have to turn on the tv manually-the roku app on the phone will change the channels but not the volume. Is there a fix for this? Can it be replaced?
As far as I know there's no way to use the app to control the TV volume. I'm sure someone will correct me if I'm wrong. The Roku remote controlled the TV volume either via IR or using your TV's CEC feature. If it used IR, then it would be impossible for the app to duplicate that. If it used HDMI-CEC, then it would be possible, but I don't think the app supports that.
