If you've got the card working at all with ALSA under Linux, then try
using the speaker-test program which is part of Alsa to test each
channel whilst using the ALSA:surround51 predefined device. With some
luck, it shouldn't need more than that.
If you then want to upmix 2-channel sound to appear from all five
speakers at once, then look at something like this in your asound.conf:
#Front left and right :
Hope that helps,
PS: The above is for an SBLive, although it should work, possibly
needing a change to the ordering of channels to get the right speakers
working at the right times!
