No sound while pay per view movie playing - DirecTV

On several occasions I have downloaded pay per view movies but get no sound while movie plays. The sound works fine on a regular tv programs and other downloaded programs which are not pay per view movies. So I am getting audio for other things, I Turned the dolby off and on, sound is not muted, and I have tried having the sound come through separate speakers and just the tv. I have gone through the steps ordering the movie and clicking ok when it asked. As I said the picture plays, just no sound.

This question, "No sound while pay per view movie playing," is about DirecTV channels, programming, equipment, and sports.
