Sound... Jumps? Skips? on not only Apple TV but iOS app as well.....

When I try to play any video, any file what so ever, from any source on my Apple TV or even my iOS device, the sound skips. And I guess “skips” would sort of be the correct way to explain it? Like, 1/2 second of sound will play, then 1/2 second of sound will sound, I guess, degraded?

This is any file type, even when playing from Comedy Central’s Channel.

And, this also happens on my non-beta iOS device. But web browsers play it fine.

My apologies, I stand corrected. It turns out its .mkv specific, and x265/HEVC… I just test-played MP4 files, and they all played fine
