The device does support hardware mixing. I can take inputs coming into

The magic is created by the hdspmixer application written with love
and care by Thomas Charbonnel and initially debugged by Thomas &
myself back in 2004 I think. (Maybe 2003)
Hardware mixing works identically (well, very closely) for Win XP and Linux.
Note that the big difference between the Hammerfall and HDSP lines was
the addition of hardware mixing.
Hope this clarifies things a bit.
