Until very recently, I had no problems with the sound from my Beam. Then starting a week ago, I couldn’t change the sound volume, or mute the sound. (The on-screen sound volume bar showed volume increasing or decreasing, but no actual sound volume change occurred.) Today, the on-screen sound volume indicator shows that the sound is muted, and I cannot unmute, or increase volume. I can get sound from the TV speakers, and the on-screen sound volume indicator works. I tried (1) cycling the Beam off and on, and (2) switching the TV sound output between TV and Beam.
