The audio settings on my grandma's Comcast cable box keeps changing randomly. Every couple weeks it has been changing from English with descriptive video off to Spanish with descriptive video on. Several channels change to Spanish or lose audio. This has been going on for the past couple months. It cannot be the box or the TV, both have been changed. I'm at a loss for an explanation. The remotes don't have an SAP button, and I know she isn't going in to the menu and changing it herself.
