Some shows have no audio on appleTV

I am using my appleTV. It has audio to the TV. I tried netflix. I tried another show in my purchases. Those worked. For some reason, the mid-season finale and other Walking Dead shows have no audio. But the preview for them does.

I'm assuming this is an apple glitch, which is upsetting considering I paid for the season pass so that I can watch the show on my appleTV.

Any help would be appreciated if anybody else has this issue and resolved it differently? I've tried restarting and resetting. I'm about to log out and back into my appleTV in hopes that maybe that would fix it.

Thanks
