I decided to buy a Roku TV about 2 weeks ago and so it’s been great, until the last couple days. I will be watching a movie and the remote sitting on the coffee table and than all of the sudden the volume is being lowered to 0...I turn it back up to 14 or where ever I had the volume and it will go down again....it happens multiple times a day and I’m not sure why. There is nothing but the power cord plugged into the tv...I have no outside speakers or anything...even now trying to watch the news while making some coffee and all of a sudden I can’t hear the news and I walk in and the volume is on 0....mind you I have no kids and live alone so this makes no sense
