Matthew laments that while he's wired for 7.2 surround sound, he's not getting it because Sony's engineers didn't allow for LPCM pass-though over HDMI-ARC from the PlayStation 4, forcing him to set the PlayStation 4 Pro to DTS bitstream, leaving him with only 5.1 surround.

"It's terribly frustrating," Matthew says, "and until I upgrade the receiver to a HDMI 2.0 compliant model from Sony, the PlayStation 4 Pro will remain connected to the 4K X850E first and audio pushed via ARC to the receiver."
