Oh does it? How about adding some references to this claim?
Might be
actually convincing then.
At least I couldn't find anything googling for 'HDA hardware-
mixing'.
Nor could I find anything googling for 'HDA multi-analog'.
Please check your dictionary and look up "to tout". There
you'll
find
that it means "to solicit, peddle, or persuade
importunately".
It's
not particularly "importunate" if google can show no trace
of
it, is it?
And also, please paste a dump of "amixer -c0" for your HDA
card so
that we can see that it includes a "CD" control. And the
contents of
/proc/asound/pcm would be cool, too, so that we can see your
HDA card
does hw mixing.
If you cannot produce anything of that I'd recommend a good
ol' cup of
STFU.

I see a "CD" control here. Not sure if anything indicates hw-
mixing or multi-analog, but here's stuff from a recent (ASUS
P5Q-VM) motherboard release late 2008[1]:
