People associated with ALSA have been daft enough to say that before about
sound cards that had exquisite hardware mixing, is it really too much to
ask for a simple parcel of information that appears to be omitted from the
documentation I can find for ALSA? I swear, if the consistently
condescending/fek-you attitude from ALSA over many years is any indication,
no wonder it moves like slag compared to other sound drivers and almost
never gets reasonably "full" support for any particular chipset. -_-

I already said I wasn't looking for more statements of non-support, but just
how such things have to be done in the source code. People should really
read once and a while.
