First of all, I don't know much about all these receivers. I bought this Yamaha HTR-5790 about 3-4 yrs ago when HDMI and HDTV weren't all that common. I have a simple 5.1 set up.
Over the weekend, I bought LN52a650 and a PS3. My problem is with PS3 audio output to the receiver. Since I don't have HDMI in my receiver, I connect the HDMI out from PS3 to the TV and the digital audio out to the receiver. My intention is to mute the TV speakers (which suck) and use my receiver for audio. But, even though the receiver tells me that it is getting PCM input, I donot hear any thing from the speakers. I did a similar thing with my HD cable receiver. Connected the HDMI out to TV and digital audio out to receiver and instantly I get the 5.1 blaring in my room.
So I am assuming that the audio output from PS3 is in a format which receiver does not understand? Any suggestions? Thanks.
