What brand and model of headphones are these, may I ask?

well, what i did was just buy a simple converter cable from radio shack. on one end is a simple headphone plugin jack, and on the other are audio jacks to plug into a surround sound unit. I did this in my room and the surroundsound is AWSOME.

Thanks for resurrecting this, cargenius. I missed it earlier, and reading it has given me a good giggle!

If that receiver/stereo/whatever has an inbuilt surround sound amp, then ANY stereo soundcard can be used with a suitable cable. A better card will produce better sound, of course, but Prologic only needs a stereo source

Catweazle's right, as usual. I run a 600 watt Pioneer Home Theater system connected to my SB Live, with the optional Digital IO daughtercard. PC games, so far, seem to use Prologic, and for Prologic, if your amp has it's own decoder, than all you need is a stereo output.

If you want real Dolby Digital 5.1 sound, (so far, no PC games other than Doom 3 I know of support true Dolby Digital 5.1 sound in full), then you want digital IO, (SB Live 5.1, or Audigy or the like). Really, unless you're watching DVD's on your PC, (like I do), then you don't really need 5.1 on the PC. That will change, though. It's only a matter of time before games supporting full, true Dolby 5.1 will appear for the PC. (Playstation 2 and Xbox both have it, why it's taking so long to hit the PC I'll never know).

I've noticed it seems a bit trickier to get true surround sound on your AV receiver with an Audigy 2 ZS soundcard. Even though it has digital output via a 1/8" plug, the signal that comes out needs to be decoded by a proprietary Creative Labs device. So when I plug that signal straight into my coax input on my AV Receiver, i get L/R front and that's it.

It's very dissappointing. Someone mentioned a work around via soldering straight into the card but I don't know if that gives you a true 5.1 surround digital feed or not. Anyone try this?
