I got the Aureal 8310 (PCI Quad) - and it was and still is, on of the BEST cards on the market.. Even though It "only" got up to 4 sound sources (thru spdif), it supports A3D 2.0 and when you use it under win98se or winME (yuck) - you get it's full potential.. the sound is amazing.. it's real time surround.. unlike pre-recorded surround. You walk around and experience the game world in a different way..
If I could get multi speaker support with it under winxp, I'd be a happy man.. oh well, at least I got My nforce (1 with Soundstorm) which got Dolby Digital encoding

It's not about hardware hacking.. more like driver hacking. and since the "great" creative would not release the specs and materials about the vortex processor, no one in the open source community can engineer new drivers.. well, aside from the linux ppl, but that doesnt help me.
