March 14th I had my 622 installed with a D1000 dish and all my HD channels were fine. Sound worked great. Then tonight I came home and I got no sound on any of my HD channels. I am using the Optical cable for sound. Now if I went into my DVR menu and watched something I recorded in HD it had sound but none of the channels had sound except for non-hd channels. My signal on 129 is 64 - 69. Anyone know why this is happening? Does this happen often?
