I've had a problem with drop off sound for some time. I usually channel up one on my remote and then channel back to the channel I was watching to get the sound back. I've reset my box, called Verizon and had my box reset remotely, and recently had new sofware added to my Motorola box remotely via chat support. I still have the problem. Last Saturday, I used on demand for the 1st time to watch a movie and every 10 minutes, the sound would go off and come back after 2 minutes. Can anyone help? I have a Sony Bravio LCD TV with HDMI cables hooked to a Verizon HD Motorola box. Thank you
