The sound drops out while watching CNNHD . Switching to CNN non HD and the sound returns. This issue happens after I have been watching CNN HD for about 30 minutes or more. I have not noticed any sound issues like this with any other channel .
I am having the same problem it happenes throughout the day and night. It lasts about 1 minutet then it is OK thill the next time. It has been doing this about 3 months. I have reported and tech say its fixed. However it has never been fixed.
