Sorry to resurrect an old thread, but related to the issue bothering me...
I have the Pioneer VSX1124 that has dual HDMI outputs, connected to my Plasma and Projector.
From the PS4, I get the Stereo PCM issue many have experienced in the thread.
But here is the weird thing, if Im using the projector and turn the Plasma on and then back off, the Stereo PCM kicks into Multichannel PCM.
This seems to be the only way I can get Multichannel PCM from the PS4. If I just use the plasma, or just use the projector its in Stereo. But again, when using the projector and turn the plasma on/off kicks into Multichannel PCM. Very strange, and annoying as it should work correctly to begin with. I dont want to have to always use the projector just to get Multichannel, I like playing on the plasma sometimes.
Im wondering if there was something in one of the updates that makes the PS4 output act wacky?
