My 2011 Panasonic TC-P50GT30 (hdmi 1.4a) connected via HDMI-1 (ARC) to my Pioneer AVR VSX-1121-K (hdmi 1.4a) via HDMI-out (ARC) is only passing 2 channel PCM Stereo from my Sony PS3 Blu-Ray connected via HDMI (Bitstream or LPCM) on my plasma. I called Panasonic Support and Pioneer Support and both claim ARC only passes 2-channel LPCM Stereo. Can anyone confirm this? After all what's the point of connecting high-def audio content like DD Plus, Dolby TrueHD, DTS-HD, etc. to the TV HDMI inputs when all the TV will pass is 2-channel audio to the AVR?
