You guys are morons. All EAX x.x does is create more realistic audio in games. Once all that info is calculated (by the sound card), it simply has to be output. You can do that with 6 (or more) analog jacks in the back of the card, or you can encode those multiple channel LPCM signals into a Dolby Digital or DTS stream and send to a receiver that way.

The digital S/PDIF spec doesn't have enough bandwidth to send all channels digtally, so they have to be compressed via Dolby Digital or DTS encoders (like going from WAV to mp3).

Not all surround receivers have 5.1 (or greater) analog inputs (like mine). So the only way to enjoy the EAX 5 in something more than stereo is to have the sound encoded into Dolby Digital or DTS.

Since you sound like you don't know what you're talking about, Dolby Digital and DTS are nothing more than a way to compress multiple audio channels to save bandwidth (again, like going from WAV to mp3). It can have EAX 1/2/3/4/5/x produced audio, a movie soundtrack, or whatever.
