    My Dolby digital light comes on on my receiver when I used to play Gran Turismo 4 (and many other games) on my PS2. It was hooked up via optical cable to my receiver. It was definitely Dolby Digital 5.1. Funny thing is it went off at times depending on what part of the game you were in. Like cut scenes, etc.

    I think sometimes it was just using the rear left and rear right as one channel but still had a separate front left, center, front right, and sub channel when in that other mode. Basically 5.1 with the rear two satellites being used as one channel when the "Dolby digital" light was not on on the reviever...

    hmm, i was never aware of that. I have my PS2 hooked up via optical, but I have never noticed if a game used DD.

    Hi,
    I have a problem with the Creative Xfi Xtreme Music and Logitech Z-5400.
    I have a problem when I play DTS cds. If I do the decodes through Xfi it's all ok, unless I must use the Creative MediaSourceReader, with the others software
    it does not appear written DTS on the desktop and only a noise is listened . If I do the decodes through the external Logitech connected in digital (coax), the sound is accelerated, like if the “scale time” were active from the MediaSource 5 (on the desktop it appears written bitstream digital out and on the logitech dts digital).

    Someone knows because it happens? excused for my English.
    Thanks

    Hello,

    This is a really interesting thread. But since its beginning, you've talked about the SPDIF output only, and not about the input.
    I'm looking for an audio card which can acquire a multichannel source with SPDIF connection such as 5.1 at least. I would like to know if this kind of card exists and if we can extract after treatment and decoding the different channels.
    I've already seen the Auzen X-Meridian 7.1 but i'm not sure if it's appropriate to me.
    Can you give your opinion and advise me about the different possibilities existing ?

    Thank you for your reply.

    most consumer grade cards that support AC3/Dolby Digital or DTS decoding will allow that

    No, what i mean is i want to connect the Dolby Digital output of my digital satellite receiver in a sound car via SPDIF input in order to acquire the Dolby Digital. And after, i will decode the signal.
    But apparently, most of the sound cards doesn't offer this possibility. Maybe, i'm wrong, i don't know.
    What i know is there's a mode called PassThru in some cards that allow to let pass the signal via the SPDIF output without decoding it. I would like the same possibility via the input SPIDF. Is it possible ?

    what do you want to do the decoding? your soundcard? or another device? your post was a little confusing

    most mid to high end consumer cards i've seen have passthrough and decoding, even a soundblaster live! will decode ac3, and output it to 5.1 analogue.

    What sound card are you using? and again, your post is a little confusing

    I use an E-MU 0404 but i know it's not compatible with the Kx drivers.
    When you said most of the cards have passthrough, i answer you Yes for the SPDIF output, but i'm not really sure for the input. And it's precisely that thing i need in order to decode the digital flow with a software.
    So, i'm looking for an audio card which is compatible with Kx drivers and always marketed because most of the models Kx give are not marketed anymore.

    ahhh the 0404 is not a consumer card, so won't have any consumer audio features like dolby digital decoding

    fresh one...

    hi there...i'm gonna borrow this thread a bit :rolleyes:

    i recently bought logitech z-5500. i tried the boundled cables, and then i figured that spdif has better quality. so i tried the coax spdif....i was like :drool::drool: nice sound :D

    but then when i started to play a bit with the settings, i found out that my mobo doesn't support dts/dd encoding aswell (maximus formula)... so i started to explore around the web and search for some anwers...

    i knew i have to buy new sound card, but all threads are old...and i'm a bit confused what-to-buy

    i wanna buy something new, not too cheap because i intend to use it later on too...i think that it should be for pcie x1 socket (perhaps x4 too if i can connect it on the other pci-e x16 for crossfire), and it definatelly has to be able to encode dts/dd.

    i so far managed to found:
    - Auzen X-Plosion
    - Auzen X-Fi Prelude

    but they both require pci (not pcie), and i don't know if they're good...i found some critics about X-Plosion, and i don't know if Prelude is really worth of its money...

    could you recommend me good soundcard?:confused:

    the converters in the Auzentech cards are much better than those in your speakers - so if you get one of those cards, just use the analogue connections (you're wasting your money on high quality analogue cards if you get one and just use the spdif)

    aha...so actaully you recommend me classic jacks instead of spdif...

    then i should buy better cables too. better shielded perhaps?

    or should i buy cheapper one...some people recommends me to buy Club 3D Theatron DTS Agrippa 7.1 PCI instead, and connect it via optical spdif

    yes, with a decent soundcard and decent cables you will ALWAYS get better quality over analogue than Dolby Digital (Dolby Digital digital is a compressed codec, like MP3, and allows only 3 full range channels, the rear channels are limited from 10hz to 7khz, and the LFE channel is anything below 80-150hz [depending on the encoding])

    I'm still getting no luck with DD processing, even using the new driver(s) from CL and PAX.

    Simple setup, have a Comcast HD box, trying to run TOSLINK OUT - and IN on the X-Fi front panel.

    Have jacked with all the settings, un-installed / restart clean everytime.
    No luck.

    I DO get audio using standard composite cables, but that's not why I bought the damn card in the first place.

    Are the newer drivers still not able to decode on the OPTICAL IN ?

    i bought club3d theatron 7.1 that i said...but i had problems (i guess it's because of Vista pro x64)...but my friend bought it from me :)

    so now i'm looking for new sound card again...i was looking @
    - razer barracuda ac-1 (which i don't really like, mainly because of its connector for jacks)
    - creative x-fi titanium fatal1ty pro (i'm not really sure if it's capable to encode dd/dts on the fly for spdif)
    - auzen cards are not availible in slovenia :(

    then i was searching a bit for better quality cable (if i would connect the speakers throu analog connection), and i didn't found anything ^^
    is it worh if i would buy cable and connectors (seperatelly) and i would "make" the cable?


    ** edit:
    i was looking @ club3d theatron and it had lousy instructions, and it didn't have anything mentioned about front panel connector...i've got thermatake xaser vi, and it has connector for hd audio and connector for realtek ac'97... does any of mentioned sound card support front panel connector?

    Hey guys i was wondering if you could help me..
    Im using an Asus Rampage formula with windows vista 64 bits , my Supreme fx-ii and onboard audio can't give me 5.1 in games with spdif , so i was wondering which sound card i should buy ?

    Motherboard : Asus Rampage Formula
    Sound system : HTPGS1
    Audio / Video Inputs: Analog/Digital: 2 Optical/1 Coaxial/1Analog

    I live in canada if that can help for product disponibility
    Budget : 100$ (can spend more but im just looking for 5.1 nothing too fancy )

    PS: My apolagies for typos and such , English is my second language

    Wouldn't it be easier to just get a 7.1 channel AVR (like the one I got last year) that has multi-channel-input and then connect it directly to the outputs from the soundcard (C/SW---FR/FL---RR/LR---BR/BL)?

    Then maybe get an HD component cable switch-box (the three or four cable deal) ---------
    Pelican HD at circuitcity.com ------ (example) and just use the audio in/out so you can have multiple in/out for the 7.1 multi-channel inputs.

    Of course most AVRs also do multi-channel inputs through HDMI, so it shouldn't be a problem if you have more devices you want to hook up that way to your AVR besides your PC soundcard and your AVR has more than one HDMI input.

    The good Blu-Ray players will do "lossless compression" on the player via Dolby TrueHD - Wikipedia, the free encyclopedia or other lossless codec anyway- (like DTS-HD Master Audio - Wikipedia, the free encyclopedia )

    I think that's what I am going to do when I hook up my Fortissimo III 7.1, or whatever 7.1 channel soundcard I get next to my AVR..
