Apple TV app audio problem
I just installed the Apple TV app on a Firestick. On the main screen, when it plays the previews, the sound works fine. However, when I try to watch an episode of something, there is no sound. Going to the audio icon on the bottom right of the screen and selecting another language make it give a loud steady humming noise instead of the correct audio. I've tried uninstalling and reinstalling, resetting, restarting, but nothing works. Any ideas? Audio works fine on all of the other apps.
