UE55D6500 - t-gasdeuc_1028.0 HDMI-ARC Problem

[dglandry]

Hello,
Since I'm 1028, my D6500 TV does not recognize my denon amp.
Does anyone have the same problem as me?
It's very frustrating.
Is there any way to downgrade.
I just went through the forum from top to bottom and I can not believe that this is no longer possible.
I even tried Hospital Mode, but no way...

thank you
