Uncompressed or Dolby Digital?

I connect my Panasonic DMP-BD10 Blu-ray player's 7.1 analogue multichannel outputs to my receiver's 7.1 analogue multichannel inputs, and I get to listen to uncompressed PCM, TrueHD, and DTS-HD HR soundtracks, as the Panny decodes those two codecs as well and passes them as PCM via HDMI and the analogue multichannel outs.

Actually, optical/coax can do 48/24 5.1 LPCM, and tops out at 96/24 2.0, IIRC. Some receivers may or may not then add a .1 or 'LFE' channel, meaning, do bass management, on a LPCM 96/24 signal.

Good, thank you for answering that question Now I can know for sure.

Also, about optical and LPCM. I was only able to get stereo uncompressed PCM while watching the Fifth element. But when it was in HDMI, it did (at least) main/center/main

Reason I say at least is cause I currently don't have my backs connected.

But that stands to reason that optical can only pass 2.1 uncompressed. And not by my own experience but I have read other things that point in that direction as well. (Although nothing in concrete)

Also, here is further interesting info from my PS3 menus.

I can manually choose which sound I want for each audio option (HDMI, optical etc) and here is the list of supported formats via optical.

(BTW first one says Dolby Digital 5.1...but my cam doesn't pick up the bright whites in the TV very well)



So by this example, it seems either the PS3 cannot send more than a 2.1 LPCM, or its just impossible with optical. I would have to go with the latter on this, since the PS3 is quite the techno marvel.

And here is the HDMI options list, which has a heck of a lot more options. (left a few out of the pic...didn't want 3 pics for the HDMI list, lol.)
