Interesting. The ps4 is capable of 5.1, when streaming Netflix or amazon through it I get all three channels working, well as long as it's a newer movie that's coded for it (i.e. a Christmas story was only 2 channel). I'll work through some settings but I have tried to manually turn on Dolby surround through the reciever. Still only 2 channel. It's not a high end denon, I have the 2400h. Still, we've had two responses with two different experiences. One with 5.1 and one with 2.0. I wonder if it's a subscription issue, as in pay more money for better audio type deal.
its alright son, I'll fix it
