What is wrong with the sound on ABC?????? The sound will be normal than it drops down so much you can't hear it during commercials and previews. This morning I changed from CBS to ABC (10:00 am ) and couldn't hear the show at all but going back to CBS the sound is fine. What in the world is going on? This has been a problem for months and all I hear is WE ARE WORKING ON IT....any answers out there?????????????HELP PLEASE.............
