Hello. I’m wondering if someone can help me figure this out. So I’ve noticed that on my Apple TV recordings from what will be ATSC 3.0 channels play correctly with audio. However, when I try to play back through VLC or other media players on a computer I get no audio. Handbrake and other converters report there is no audio tracks on the recordings even though I can hear it when accessing through the recordings on the Channels DVR installed on my Apple TV. Anyone have any idea what’s going on?
You're not alone. ATSC 3 uses a new/proprietary audio codec.

So is there no way to achieve playback through a media player like VLC? No way to convert to recognize the audio that is there? I was actually looking at trying to burn to a BD-R for myself….
Just ask for transcoding when watching. The audio will be transcoded to aac.
No, VLC does not as of yet decode the AC-4 audio from ATSC 3.0 recordings.
This works for me
