Plex for Windows - Windows Server 2016 - EAC3 no sound

In your log, it falls back to trying to play using the eac3_eae codec, which has different errors.

Ah, thank you for pointing this out. I didn’t comprehend this correctly. So it’s trying and failing to initialize two different codecs for decoding eac3.

Edit: Here, try this. There’s a link to current LAVFilters in this thread.
Plex Media Player 3 (Windows 7) does not play/decode EAC3 5.1 or TrueHD 7.1

Thanks, I’ll take a look at this and see if it helps.
