I am using a "Home Cinema System In-A-Box" type setup (LG 5.1) and I don't know if this issue has anything to do with my receiver or setup. The following problem is that: -With the PS3 set to output LPCM 5.1, the receiver decodes it perfectly fine, sound comes from all channels and it shows up as a 5.1 source on the display window of the receiver. -With the Wii U set to output LPCM 5.1, the receiver only recognizes it as a 2 channel source (2 channel in the display window and nothing from the rear/center channels). So at the moment I am having to set my Wii U to 2 channel stereo and the receiver to PL-II Movie, which is nowhere near as good as true 5.1 channel sound! Does this have anything to do with the signal being output from the Wii U console? Are there different types of LPCM? How come my PS3 works fine in LPCM 5.1, but the Wii U not? What am I/the receiver/console doing wrong?
