That wasn't the case with me. As soon as I'm starting to config my home theater on hdmi 4 it only gives me 2 options: optical or headphones and none hdmi arc to pick. I also tried optical because all I want is a simple Dolby 5.1 experience, but instead all I have is 2.1 LPCM via hdmi arc. Yes, hdmi arc is working on plug 2 but is not registering 5.1.
