I would like some help to find a usb soundcard with successful 5.1 surround. hopefully with both oss and alsa support. and the ability to make stereo sound to come out of all the speakers.

i have checked both in the ubuntu wiki and at alsa's site. but didnt get much info about what usb card that works the way i want it to.
i read in a gentoo wiki about a card namned Terratec Aureon 5.1 Usb MkII, perhaps anyone own that card and can share their experience? or maybe something similar to that priceclass?

thx in advance! =)
