Love the quote.
You don't understand the concept of discrete audio. This so called 4.1 is not discrete.
I'll explain to you how this works.
If this so called 4.1 was discrete, it would contain 5 separate channels of audio. But the output of this creative labs card is a stereo 1/8" mini jack. Emphasis on the word stereo.
How can you have 5 discrete (meaning separate/unique) channels carrying signal over a 2 channel analog connection? The answer is: you cannot.
You would either need 5 separate analog line outputs from the card, or a digital spdif/coax line.
"When a Dolby Surround soundtrack is produced, four channels of audio informationleft, center, right, and surroundare MATRIX-encoded onto two audio tracks. These two tracks are then carried on stereo program sources such as videotapes and TV broadcasts into the home, where they can be decoded to recreate the original four channels and the surround sound experience."
"Creative Multi Speaker-Surround technology places any mono or stereo sound source in a 360 degree audio space"
Creative labs calls it 4.1 only because there are four point one speakers. EAX is borderline Dolby Surround, or Pro-Logic.
"It's true that for movies, it will default to Dolby Pro Logic"
Nothing defaults. It is what it is.
It may sound great for video games. That's fine with me. I just think it's important to know the difference and to understand why the need for 5.1 creation on the desktop mac is so important.
