I’m kind of directly affected by this as a consumer, as I am a big user of Plex, but can no longer receive sound with my antenna television if I run it through Plex.

This is because ATSC3.0 requires Plex to secure licensing for AC-4 audio in order to process the sound, which they legally haven’t been able to do yet.

Unfortunately, my reception is significantly better via ATSC3.0, yet I’m left waiting and unable to utilize it.
