Naime, Audigy kartica na 4.1 i 5.1 sistem zvucnika.

There have been a number of questions regarding connecting the Audigy to different kinds of multi-speaker systems and what effects you'll get with what sources. I and others have answered nearly every possible question, but they can be hard to find. So I have put together a (not so) little synopsis of the most popular topics:
How do I get Dolby Digital sound from the Audigy?
One of two ways:
1. Pass it through the card:
In the Surround Mixer > Speaker > Settings, deactivate the option "AC3 Decode".
In the Surround Mixer > Speaker, activate the option "Digital Output Only"
You do not need to choose a specific number of speakers, as the Dolby Digital signal is being output as one single signal.
In Audio HQ > Device Controls, choose 48KHz as the sampling rate.
Connect your Dolby Digital receiver to one of the Audigy's digital outputs. The Audigy Player has one digital/analogue output, which has four poles. When the above conditions are fulfilled and you play a Dolby Digital signal, this signal is output from the end pole (farthest from the cable). A simple 3.5 mm minijack - RCA adaptor cable will transfer this signal into the SPDIF-In of most Dolby Digital Receivers. The Audigy Platinum additionally has a standard RCA SPDIF Output (simply use an RCA - RCA connector) and an Optical Output (simply use an optical connector) which also output the signal.
2. Decode the signal with the Audigy:
In the Surround Mixer > Speaker > Settings, activate the option "AC3 Decode".
Choose the option "5.1 Speaker" in the Surround mixer.
If you are using the 3 stereo analog outputs of the Audigy, deactivate "Digital Output Only" and connect the three stereo analog outputs to the analog inputs of your 5.1 amplifier.
If you have a speaker system with a multi-pole digital input for the simultaneous decoding of three stereo PCM signals (e.g. Creative DTT3500, Creative Inspire 5700, Logitech SoundMan Xtrusio DSR-100), activate "Digital Output Only".
for DVDs:
Make sure that the DVD decoding software you are using is set correctly and is compatible with the OS you are using. You should have chosen "SPDIF" in the Audio options of the program - not 5.1 or 6-speaker.
Make sure that the DVD has a Dolby Digital soundtrack and choose Dolby Digital in the language menu of the DVD.
You do not need to connect the DVD drive to the Soundcard, as the audio passes along the IDE cable along with the other DVD information. It is seperated from the other info by the decoding software and streamed to the card over the PCI bus.
There may be issues with certain DVD Softwares in certain OSes. If you fail to get Dolby Digital, test the output of the card by playing one of the AC3 files that are shipped with the Audigy (search for *.ac3). If this works, contact the software manufacturer for assistance (or look in our forum - there is a lot more info here).
How do I get Surround Sound from Games?
Games produce a surround sound by utilising one of the 3D Audio APIs that are commonly in use - in the case of the Audigy, 3D audio is created using DirectSound3D - a part of DirectX, in association with EAX to apply effects to the positioned sounds.
The 3D Audio effects from games nearly always produce 4-channel surround, so generally there will be no output to the centre speaker in a 5-speaker system.
The Audigy will be able to output 5 speaker sound for any game that actually produces 5-speaker sound. The Goldmine demo that comes with the Audigy demonstrates this.
The Audigy takes the front and rear sounds and routes them to either the analog ouputs or the digital output, depending on whether you have chosen "Digital Output Only" in the Surround Mixer.
Choose "4-speaker" in the Surround Mixer, unless you are playing a game with 5-speaker support. Otherwise, you may get a hissing from the center speaker.
In the game, choose EAX (or even better EAX 2 or EAX Advanced HD) if you have the option - these improve the quality and reality of the surround effect.
Connection to the speaker system:
Generally, you will have to connect to a speaker system using the two (or three) analog outputs of the Audigy. (the third analog output of the Audigy wil output the subwoofer signal).
If you have a speaker system with a multi-pole digital input for the simultaneous decoding of three stereo PCM signals (e.g. Creative DTT3500, Creative Inspire 5700, Logitech SoundMan Xtrusio DSR-100), you can choose "Digital Output Only" and connect the speaker digitally.
How do I get sound from Music in my rear speakers?
If the music is encoded as a 5-channel AC3 file, then see above (Dolby Digital).
Most music is simple stereo. In this case, the Audigy can make one of two surround effects:
1. Duplication of the front channel to the rear channel:
Choose "4-speaker" in the Surround Mixer.
Choose the source in question (e.g. CD Audio) as the record source in the mixer.
Generally, you will have to connect to a speaker system using the two (or three) analog outputs of the Audigy.
If you have a speaker system with a multi-pole digital input for the simultaneous decoding of three stereo PCM signals (e.g. Creative DTT3500, Creative Inspire 5700, Logitech SoundMan Xtrusio DSR-100), you can choose "Digital Output Only" and connect the speaker digitally.
2. CMSS:
As above, but also in the Playcenter, activate the option CMSS > Movie Mode.
CMSS makes the Audigy take the stereo sound and mix the two channels to produce an effect from the rear and centre speakers.
Can the Audigy encode Dolby Digital?
"Dolby Digital Encoding" is a term often misused. It depends whether you are talking about real-time encoding, such as the X-Box, or encoding recorded music/content to AC-3. This makes sense for the X-Box because it's a games platform that will be used in people's living rooms, where Dolby Digital decoding systems are the only common surround system. Real-time encoding is impractical in the PC space, as the speaker systems used in conjunction with PCs are generally not Dolby Digital decoders, and for very good reason. The main use for Surround effects in PCs is in game environments, where effects have to be made in real time to reflect the game play as it happens. If this were done using Dolby Digital encoding, time-critical audio, such as gun-shots, would have to go through the process of being encoded before being heard, which adds approx 200ms delay. Our technology on the other hand handles multi-channel audio for gaming differently: DirectSound3D and EAX Advanced HD allows full 3D rendering of audio through multiple channels, which are output as four analog signals or as two stereo PCM signals, which is a much faster process than encoding Dolby Digital - hence practically simultaneous sound response to game action.
Encoding music/content into AC-3 format is a very different matter. This is technically very easy to do as it's not real-time. However the licence for this technology is prohibitively expensive and an application that allows you to mix your audio channels into 5.1 streams costs around £1000. We are investigating this area, but until the cost of implementing the technology and s/w comes down it is unlikely to be mainstream.
I hope that this has cleared up any misunderstandings there may have been in relation to multi-speaker sound from the SB Audigy card.
