New HD sound settings?

    So I got my RS760 Ultra HT speakers this week. I've ordered an onkyo TX-SR805 reciever, but am currently using a Yamaha RXV661 (I bought the yamaha first, then returned it to get the 805, and Video Only was nice enough to let me continue using it while I wait for the 805 to arrive). I have everything hooked up and tested, in other words, the speakers are all correctly plugged in as ascertained by the test tones and phase checking, and some surround DVD audio discs I have.

    Now, the problem. I've been out of the HT scene since my divorce in 2k3, back when DD 5.1 and DTS were the kings of the hill, as it were. So all these new HD audio formats are unfamiliar to me, along with their associated settings. I have my HD dvd players (ps3 and XA2) set to auto-select the sound output, and the yamaha set to 'straight', which seems to mean that it simply outputs the sound with no processing. IF the ps3 and XA2 are doing the processing, this shouldn't be a problem...however, it seems to me that my rear surrounds are not firing nearly enough as they should be. It's painfully obvious during scenes that I know they should be, for example, big explosions and stuff. I also bought a DTS-HD demo blu-ray disc, and there's very little action from the rear surrounds during any of the scenes.

    Now, these are big, gorgeous speakers, I'm in love with them already. The speakers aren't the problem. My noob-ness, I suspect, is. I am nearly certain that the problem is some setting that I am missing somewhere in the food chain. I tried the 'surroud decode' setting on the Yammy and that got the rears active...but the sound stage then sounded contrived, so I don't think that's it, either. Also, the yammy displays 'pro logic' on that setting, and I think that that can't be correct.

    Soooo...any suggestions? Should I take the settings in the players out of auto and set it to something specific? Or am I missing something on the yamaha?

    Thanks guys.

    I can only provide some info on the PS3 front. If you're sending your audio out through the TOSlink (optical digital), you're restricted to standard DD and DTS, in which case you tell the PS3 to output bitstream. If you're sending the audio via HDMI, I'm absolutely useless.

    Ah, yes, I should have specified, sorry.

    Both players are sending sound via HDMI.

    Not completely true. You can output 2 channel pcm and extract that into Pro Logic, Pro Logic II or Prologic IIx.

    The Xa2 has some bass issues with the latest firmware. I'll do some digging on that fix. I would check High Def Digest's news section as well.

    I stand corrected.....just didn't assume when he was talking about HD audio he meant DPL and the like. :p

    PCM I consider HD audio :)

    It is lossless uncompressed.

    Shane, any suggestions for what my problem might be?

    Will your Yamaha accept PCM via HDMI? Some don't.

    I am fairly certain that his does in fact accept PCM through HDMI but he still might have some setting somewhere set wrong and could be sending a stereo signal.

    Greg do you have a center channel, it is getting any sound or is it maybe your speakers are imaging well and tricking you to think it is?

    Shane, it does accept PCM.

    Max, Yes, I have a center channel, and it's getting sound just fine. Hmm...I'll have to do some more testing for your imaging theory. My initial response is no, that can't be, but I'm going to check anyway, lol. I'm no expert, for sure.

    I'm beginning to believe there is a setting issue involved. Most likely from the PS3 or HD player. The front panel of your receiver should mention PCM.

    Well I will throw this out in the mix. Is it possible that you just need to bump up the gain for the surround speakers?

    Just a thought....

    You should be measuring the level with test tones and a meter, not just bumping it up until it sounds good to you. If you haven't measured, do that first.
