Volume keeps decreasing when watching Roku Express or "regular" tv (thru antenna)
When trying to watch TV channels that are not streaming through the Roku Express (they are thru an antenna) or watching channels that are streaming thru the Roku Express, the Samsung TV volume keeps randomly turning down. The TV remote will work to turn it back up the first few times and then the TV must be turned off and turned back on again for the TV remote to change the volume, but the problem will recur almost immediately. This has only been occurring since the Roku Express was installed. HELP!!!
