I have a Sony STR2400 connected to a Sony PS3 (old style) by HDMI cable to BD input and then output by HDMI cable to Sony Bravia 40" television. I have attempted to set up the audio, however no matter what I seem to do when I play Blu Ray discs be they DTS - HD, Dolby -HD etc all the receiver displays is LPCM (48) , HDMI and nothing else. Any ideas?
