I'm a new user on this forum and hope someone has a tip for my issue. I have been getting brief audio interruptions on both live and recorded programming. This happens randomly and on nearly all channels. The audio is interrupted for less than a second with no video issue. When I am sending the audio to my home theatre receiver, I see the display interrupted as well. It also occurs when I am not sending to the home theatre receiver but am using the audio in the TV. I send the signal from the HR22 to my TV using an HDMI connection and send the audio separately to the home theatre receiver using an optical cable. I have been working with DirecTV case management and they replaced my DVR. Problem hasn't gone away. Anyone else seen this? Any ideas?
