I have my PS4 connected to my Denon receiver through HDMI. My audio settings are HDMI outputting PCM. Movies and other games do surround sound just fine. When I play destiny there is no sound out of my center channel. This means any dialogue is heavily muffled unless the person talking to me is behind me. In that case it sounds just fine coming out of the rear speakers. My receiver is showing Multi In as the audio source so it appears to be receiving the audio signal just fine. Has anyone else come across this ssue?
