Terratec DMX Xfire 1024
Description: An old 4.0 gamer-soundcard supporting EAX 2.0 and A3D 1.0, at least under Windows. It uses the snd-cs46xx driver, hardware-mixing works well. The front and rear plugs are sepparated from each other, see my aplay -l output. Hardware Notes: Kernelversion before 2.6.11 had no support to mirror the front onto the rear channel. Sometimes the front right output is crappy but pulling down DAC in alsamixer to 50% works well, when you make the rest louder.
