I finally got my system completed. I'm using a Marantz SR5004 avr connections are HDMI from PS3 and HDMI from avr to TV. Which audio setting is best to use on the PS3, PCM or bitstream? I tried bitstream and it wouldn't play the rear two speakers, basically I was only getting 5.1. After I switched to PCM, I now get 7.1, at least the display on my avr is showing that sound is going to all 8 speakers. I don't understand the kHz settings on PCM. The PS3 settings menu wants me to choose which one to use, I selected the highest kHz choice, but I hate just guessing stuff. Any help understanding which setting to use and why would be greatly appreciated. This is my first HT system, and I just want to make sure I'm getting the most out of my system.
