TotalMix is a big, fat, wonderful on-screen mixer that allows you to
control the HDSP9652 under Windows. The Linux equivalent is called
hdspmixer. To me it's easily worth the price of admission to the HDSP
line as you can really easily monitor input and output levels as well
as control the hardware mixer in the HDSP.

It's primarily the hardware mixer (and MIDI support) than makes the
hdsp9652 different from the Hammerfall. With the Hammerfall there is
no mixing and all level setting must be done using alsa commands.
