After days and days of looking online I've finally decided to post a thread, hopefully it wont be too much bother for the experts since, I imagine, this is pretty "newby" question.
My quest is to output the full HD audio stream of a blu-ray (or .ts, .mkv etc), decoded from its original encoder (DTS/AC3/True HD/DTS-HDMA..) to raw LPCM, without having it fall back to the lossy stream core, and I need to do it over the 5.1 analog outputs of my Auzentech Xfi Bravura soundcard to the 5.1 analog inputs of my old (w/o HDMI!) Denon 3801 receiver (which can only decode up until the old DTS-ES 6.1 Discrete). I understand it wouldn't be really lossless but the majority of the tracks in BRDs are encoded at 16 bit 48Khz anyway, and more than that I have no plans on buying a new receiver in the next few months (next year).
I thought this was going to be easy, but failed.
What I've got from reading online is that, because of PAP, the lossless audio streams will always be downsampled to 16-bit 48Hz, unless bitstreaming in HDMI over Radeon HD5xxx and other (Ausus Xonar?), but what I'm wondering is how to at least get the downsampled full bitrate HD stream instead of only the lossy core stream.
Is that possible?
Because, for example, using mpc-hc with fddshow audio decoder to output in LPCM 5.1, I can watch a movie with both Dolby True HD and Dolby Digital 5.1 tracks and I can select no problem the Dolby THD track... but nontheless I read "16 bit, 48Khz, 640kbps
". Damn! That bitrate (sooo low eheh!) is that of a simple AC3 "core" track (I do know that Dolby doesn't really have a *true* core track like what DTS HD/MA do) :-/
Even more absurd is that, no placebo effect trust me, on the Legends of Jazz Showcase BRD selecting the Dolby True HD track (and, again, mpc-hc reports I'm listening it at "only" 640Kbps when I go to the internal audio switcher) sounds MUCH better than the other selectable track, the lossy AC3 DD 5.1 one which instead should sound exactly the same (being that is encoded at 640Kbps -like the "core" on the True Hd track)!
Enlighten me, please, and if possible help me out getting the best I can without resorting to ripping audio to Flac&co, or changing my soundcard.
I'm definitely open minded about buying new software tho.
Thanks for reading!
Problem with the threads I've found all over the net is that they always refer to bitstreaming, while I need those HD audio streams decoded in software to "raw" LPCM and then outputted over ANALOG 5.1, not HDMI (unfortunately!), so I still can't seem to get a definitive answer... maybe I'm blind, but man you would do me such a big favour just to take the time and answer, even if only a couple of lines! ^_^
