Came across an issue I can't resolve tonight, and I'm hoping someone can point me in the right direction.
A little background before I dive in. I have a 65c7p oled connected to a Pioneer VSX-LX101 receiver at my house. When I hit the source button on my remote for my LG TV, it will display all of the sources connected to my receiver, assuming via HDMI-CEC.
So now on to my issue. I was helping a friend connect his new Onkyo 686 to his 65b8p oled TV tonight. The receiver is very similar to my Pioneer, since they're both made by Onkyo. When we connected his receiver to the TV and hit the source button on his TV remote, it's only showing his PS4 as being connected to the receiver. It's not showing his Directv Genie box that is also connected. If we manually change the input on the receiver to CBL/SAT, it will let us watch Directv of course, but it's strange how it won't detect the Directv box as an input connected to the receiver. I went into the settings on the Directv box and confirmed that HDMI control is turned on, so I'm kind of at a loss.
Is this an issue with the Onkyo receiver? Directv box? Or possibly something wonky with the HDMI cable?
