OK. The problem seems to have been fixed! I went into Device Manager and uninstalled the Realtek HD Audio. When I rebooted, the program installed as "High definition audio device". I changed the APP for .mp4 to Films & TV. I then went to my Bourne movie and all sounds were able to be played.
I must remember this just in case it happens again.
