Thanks! I applied this to the "next" branch.

If you feel like doing more polishing work, it would be nice if you
could add the surround21, surround40 and surround41 device definitions
for this card to alsa-lib in a way that doesn't move the LFE channel to
a wrong position, and then change this configuration to use the
appropriate alsa devices rather than using surround51.
