Every 30-60 seconds the audio will just cut out for 1-2 seconds. It started out as a very infrequent problem but has only gotten worse and worse over time, and affects both live tv and dvr recordings. It only happens on the main tv box and none of the minis. I'd rather not replace it if possible as I'd hate to lose all my recordings. So far we've tried restarting the box multiple times, reseating the coax cable, and swapping out the hdmi cable. Any help or suggestions would be greatly appreciated.
