its not true to say that with ALSA, they support what is commonly
understood as h/w mixing. you cannot do independent open's of several
subdevices and get the output of each subdevice mixed down to the
outputs.
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.
