Yo, back on Thursday 06 May 2010 Florian Faber was all like:
Reuben,
I remember being a bit surprised when I first saw that there were 64 playback channels,
but at the time I tried them all and I could route any of the 64 playback channels to any
of the 16 outputs. Didn't think to test if there were limits to how many I could use
at one time. But that was two years ago. Haven't had a chance to play with it since
then. Have been thinking of getting one myself (or something similar) to replace the old
RME 96/8 PAD I've been using for quite a while now.

Alsa exposes all 64 matrix inputs as alsa ouputs,
and I don't think
the windows driver does that. (Never played with the windows driver, so
I may be wrong about that)
Than that's a bug in the snd-hdspm driver.
IIRC, they put such a huge matrix on it because
they designed one
chip to slap on all their cards in that family. Saves money to just design
and fab one chip instead of a separate chip for each unit.
It is an FPGA, so it's just a piece of firmware. If it really works to
pass along 64 playback channels instead of the 'official' 16 (I don't
know, I don't have an AES card), I really wouldn't recommend using this.
If one day the firmware gets modified to add new features, some now
officially 'unused' multipliers might be re-used and things will break.
After all, there is just a limited number of multipliers available.
