Sound cutting out constantly

What I REALLY don't understand is with all of the posts from people having the same issue (sound cuts out during live and DVR), not to mention anyone who DOESN'T post, why isn't Comcast doing something about the issue or posting a solution, instead of these constant please message us PRIVATELY and we will look into your issue.  This is NOT isolated, so obviously there must be something wrong with the product i.e. the tv box, equipment, you name it.  Comcast needs to take ownership of this issue.

We have dealt with Comcast/Xfinity for many years and nothing has improved.  If this keeps up for us and I keep reading posts of ongoing similar issues from other users and NO solution from Comcast, we may just have to go back to Direct TV.
