I have a Denon 2807 receiver and am connecting my Playstaion 3 to the reciever through HDMI. I had it connected through opticle but I was told that I could get the PCM sound format with the HDMI cable on the Playstation 3, wich sounds better. I am only using HDMI just for the audio not the picture because I currently do not own a HDTV. I set the reciever to HDMI and then set the playstation 3 to HDMI. So I put in a Playstation 3 game (that has Dolby Digital) and it dosnt swith to dolby digital or PCM. I dont know if the game I was playing has PCM but I know for a fact that it has dolby digital On the reciever it says something like Multi CH PllX music. It wont even let me switch the reciever to cinema. What am I doing wrong?
