In the last week or so the audio for the NBC affiliate in Dallas has been muffled. Sometimes it's only on commercials but sometimes it's on actual programming. For example, right now the audio on Jay Leno is muffled (sounds like someone's talking into a pillow). I noticed tonight that I'm having the same problem with Universal HD. As far as I can tell all other channels, HD or SD, are fine. Anyone else in the Dallas area having this problem? I'm trying to decide if the problem is with my 622 or on the broadcast side. Note that I get the same thing via OTA or sat-delivered HD.
