Audio drops on fox sports and NFL Network between commercial breaks

Been having this happen more often. First noticed after upgrading my mini box to contour. I've only found this on fox sports network and NFL network. Talked to "chat" and they re-set my box, hoping it would fix it, but it happened again less than an hour later. Please...help me. baseball and football are my passion.

We have 3 tv's with mini boxes and 1 with contour, and it's the same on all.
