Well, this evening during WML and IGAS on GSN, there was no sound during the shows, but the commercials and promos came through loud and clear. I flipped channels and there was sound, so this was a GSN issue. Maybe Davidson was manning the controls at GSN during his hour of shows.
I also had this issue on last week's FF with the dummy contestant who answered "alligator" for an animal with three letters in its name. The main game had sound but Fast Money did not.
BTW - Davidson's hosting this evening consisted of short clips of him making brief comments. IMO, he looks like a 60-year-old hippie with that long hair.
