Roku soundbar - all of a sudden I cannot adjust the volume
All of a sudden (been using the soundbar for months) I cannot adjust the volume. When I try I get a soundbar indicator, and is shows Recever (hdmi). Cannot find anything to change this, tried batteries, power cycle, disconnect and reconnect.
Roku Sound Bar --> TV (HDMI Cable, and Optical Sound Cable) -- worked fine all the time, all of a sudden not working.
