its not true to say that with ALSA, they support what is commonly

yes, they do have a very powerful h/w matrix mixer, but it is not
accessible via a series of independent subdevices. it also is not
supported by the ALSA mixer API at this time.

I can confirm the RME HDSP 9632 cards and add-ons
also support hardware mixing.
They work really well too I may add.
I stand corrected. Mark was right - these devices do have hardware
mixing, they just implement it in an odd way, probably to keep the
interface similar to other OS.
