I have a 65 inch Roku Tv and my volume has been acting up lately . It’s been about 3 months since I’ve had it and thus problem just started for about a week or two now . Sometimes the volume works and some times it don’t . In order for me to get the volume working , I have to unplug the tv and plug it back in . When I do that , sometimes it work and sometimes it doesn’t . Is there anything I could do ? Suggestions , updates ?
