GRID - Dolby Digital 5.1?

Creative Audigy - I just seen the DD logo on the disc and wondered how to activate it. I'm using the SPDIF passthrough to my receiver via co-ax
 
I'd like to know this too. I'm using optical to my amp and can't get any games to work in 5.1. All mkv's and DVD's work fine but nothing from COD4, crysis, grid etc?
 
wont you have to use the creative alchemy in order to get this to work using D3D, then it should work in 5.1?

I am unsure since i haven;t used a creative card on vista. <3 D2x just working.
 
from what ive gathered, you need a soundcard which is capable of dolby digital live. this converts it then is able to send it via the S/PDIF or optical cable

also off of wiki

Dolby Digital Live

Dolby Digital Live (DDL) is a real-time encoding technology for interactive media such as video games. It converts any audio signals on a PC or game console into the 5.1-channel Dolby Digital format and transports it via a single S/PDIF cable.

Dolby Digital Live is currently available in sound cards from manufacturers such as Creative Labs, Turtle Beach[2], HT OMEGA SYSTEM[3], Auzentech[4] and Asus[5] using C-Media chipsets. The SoundStorm, used for the Xbox game console and certain nForce2-based PCs, used an early form of this technology.

DDL is also available on motherboards with codecs such as Realtek's ALC882D,[6] ALC888DD and ALC888H.

DDL is also supported by all Creative X-Fi based sound cards, but is intentionally disabled in the drivers by Creative on all but the Auzentech Prelude. A programmer named Daniel Kawakami has re-enabled this feature and fixed other bugs in the Windows Vista drivers in a series of modified drivers that he made available. Creative Labs has alleged that Daniel has violated their intellectual property and has demanded he cease distributing his modified drivers [7] [8]. Creative has since released the X-Fi Titanium sound card which fully supports Dolby Digital Live.

edit : i think the drivers ive got for my xfi enable dolby digital live actually, ill test it on chaos theory now
edit2: it doesnt change the output via S/PDIF for me at all, no matter what i set it to in the creative control panel

Is it DD 5.1 or DD Live ?.

There is nothing in the Games settings to state anything.

And Alchemy is only needed if a game uses Older (some still do) DirectSound over OpenAL.

I dunno about dolby digital, but patch the game to 1.2 and the game will set itself automatically to that what windows is set to.
I only had stereo sound in 1.0, but in v1.2 5.1 worked great :).
 
^I'll try that later as I'm only on 1.2 I think. Snowdog is that through an av amp?^

I need to try Lego Indy too as that has the DD logo on the box too.

What about COD4 then? It has a 5.1 option in the menu but I still only get 2ch on the amp. I've tried the option for default windows sound but it's still only 2ch.
 
I'm not sure that i want that many more cables into my amp!

Looks like I need a sound card that does Dolby Digital Live. Better start saving for a Xonar D2X!
 
Onboard realtek on a P5K-E. It's been hard to find any proper info on it but it doesn't seem to support DDL.
