I have been having a persistent problem with my 940C that is driving me nuts. I cannot get Plex or Kodi to pass anything but two channel audio over the optical cable no matter how many times I change the audio output setting (Yes, I've read the discussion about options 1 and 2 and I've tried that). I'm starting to think this is a firmware bug with no work around. It is annoying, because it USED to work.
I don't care about apathy
