Onkyo Tx-sr705, PS3, BR Casino royal...No sound! Help

How i have things set up.

On the Onkyo I assigned Game/TV to Hdmi input2. I have the Ps3's hdmi therefore attached to the Game/TV input(hdmi input 2). I have the Ps3 outputting PCM over hdmi (no video since that has to be over component). When i play the movie (Casino Royal), it shows on the receiver "dolby digital" but i'm getting no sound. I tried the bitstream setting on the PS3 once and that didn't work either. What could I be doing wrong? Just got this reciever and was planning a couple flicks after the feast tomorrow. Not looking to good so far.

Is there a way to tell the receiver's HDMI input 2 to expect PCM HDMI since that's what you've selected the PS3 to output through its HDMI output? That it says Dolby Digital might mean that it expects a bitstream from the HDMI input when it needs to be set to receive PCM multi-channel audio.

I tried to find a way to force it pcm but no luck. It just automatically picks up the format. Sometimes it will say pcm. Sometimes it will show the DD symbol. I tried just an analog source over the cable/tv input (RCA's) and found that I could barely hear the signal over the speakers on max volume. Something definitely wrong there. It's also only maxing out at about +18 decibel on the volume and bottoms out way in the negative. Wired. Never had a receiver show volume level like that. Wonder if the auto speaker setup screwed things up. The screen always shows Audyssey on it too. Not sure if that is significant or not. I'm totaly baffled now. Guess it's tech support time unless an Onkyo 705 owner can help.

"Forcing" the receiver to decode a format that isn't present won't result in any sound being generated. So it is totally normal for the receiver to display DD, DTS, PCM, etc when those formats are what it sees on its inputs (this is why for years I've never understood why a manufacturer would design a receiver that doesn't always automatically detect the signal coming in).

Just guessing but sounds like the Audyssey feature is screwing up something - deactiviate it and see what happens.

And if you can't get it to work on Turkey Day, just use the PS3's regular digital output until you can.

Well, knowing that Casin Royale provides both English: PCM 5.1 (48kHz, 16bit) or English: Dolby Digital 5.1, forcing it to pcm should be ok. Not that I can anyway. With PCM selected on the PS3 it detects dobly digital most of the time. Shouldn't it only detect Dolby digital when the PS3 is set to bitstream? Not PCM? That's what I thought the manual indicated. I could give the digital out a try. Point is Ishouldn't have to. I checked and the manual says the Audyssy display on the screen is normal. I think this may be defective because I should get sound no prob via the analog RCA's from my Sat/Receiver. Instead I could barely hear it at max volume. What a drag.

Update: Tried my Hd-a2 and transformers and the receiver picked up mutli channel pcm 5.1 and worked just fine it seemed. So, maybe my PS3 is defective sending the audio formats. However, the problem still exists where I get very very low audio from all the analog inputs. So the receiver still may be defective. Apparently no Techs until monday.

I hope I'm using the correct terminology when it comes to the PS3 (maybe someone who owns one will chime in?) but setting the PS3 to detect Dolby Digital sounds like you would be telling it that when the disc has a DD track on it send that as a bitstream to the receiver (pretty much like with a standard-def dvd player).

But if you set the PS3 to detect PCM, the PS3 takes whatever audio format that is on a disc, converts that to PCM, and sends that to the receiver (since there are still many receivers that can only handle PCM [and regular Dolby/DTS of course] via their HDMI inputs).

As far as the volume level issue: does the Onkyo have a preset volume limit parameter that the user can program? I think I have seen that somewhere in one of their receiver's menus on a couple of their better models, but that was awhile back & can't remember the particulars too well.

Weird! I was looking at that very HD-DVD disc at a Best Buy a few days ago (it was playing as part of an HT demo system) and looking to see what audio formats it offered. At least on the disc's label I saw no mention of PCM, just Dolby Digital Plus.

I checked again to make sure because 1) lossless audio was one of the big features frequently touted at the introduction of both hi-res video formats and 2) I thought a movie - which is on my Xmas list

- with so many sound effects would use a non-compressed format to allow the audience to hear them better.
