[alsa-devel] [PATCH - alsa-lib 1/1] add surround21 for Echo3G devices

[Tom Yan]

different from what? each other? you mean the confs (yeah that's why I
pasted the links) or the actual cards (so that they derserve confs in
different from SOMEHOW)?

and emu10k1 doesn't even have "side".

I know some of the confs use multi and some use front. that's my
question/doubt, coz that seem to imply that some of their drivers are
sort of "incomplete".

and you haven't been really making any point/sense tbh. i don't feel
like i should continue any discussion/conversation with you. it's out
of the scope of my patch anyway.
