I’m seeing this problem on only one channel.
When I’ve been watching football on my local fox station, often, during commercials, when the commercials switch from one to the next one the audio will drop out. The only way to get it back is to jump back to the guide, then get back into the game.
As I mentioned, I have only noticed this on my local Fox channel. Also I’ve been recording the games when this has happened.
Any clues?
