You are leaving out a lot of details for anyone to answer your question. Like how are you receiving your signal, sat, cable, OTA? What type of equimpemt do you have?
I just finished watching the ALCS game on FOX and was receiving a DD audio feed that sounded terrific. I was watching it OTA through my Samsung DirecTV HD sat receiver into my Denon 3805.
I hope that helps.
Oh, maybe you meant fox cable???
