onkyo 606 and ps3 audio question

[vonzar]

I am new to the world of lossless audio and have a question about my new onkyo 606 with my ps3. I have had my ps3 since launch and have been watching blu rays ever since. I was ignorant to the potential for audio on blu ray until the middle of last year, then I started hearing about lossless audio and how great it was. I decided that I wanted to find out for myself but decided to wait upgrading my receiver, since I heard that the ps3 couldn't decode the DTS-HD MA and thought it likely that sony would fix that through an update. Of course they did, and so as soon as I could afford the onkyo 606 I got it and I recently hooked it up. My question is when I push display while watching a blu ray on my ps3 it will show the audio being used, and when my ps3 shows Dolby True HD or DTS-HD MA my receiver shows it is PCM. In fact that is all my receiver will ever show while listening to anything. PCM. Is this a malfunction of my receiver because it has not once shown that Dolby True HD or DTS-HD MA was playing, just pcm. Or is this a setup problem. I do not know much about these things and I am sorry if this has been discussed before, but if this is something that is normal due to the capabilities of the ps3 or onkyo 606 will someone please let me know why, because as far as I have heard they are both capable of decoding DTS-HD MA and Dolby True HD. I would greatly appreciate some clarification. I would just like to know if it is a setup problem or if I am really hearing the right sound.
