Advertisements Today, I changed to a live OTA digital channel and had no audio. The problem appeared every OTA digital channel, but not any of the D* channels. Recordings from OTA digital channels in the playlist from a few days ago had audio, so I ruled out a problem with settings, cables, or TV. I re-booted the HR10-250 (6.3a) and now audio is back to normal. I have no idea what caused the problem, but the re-boot cured it.
