no. i think u not understand what i need.
once again.
i need independed streams.
i have no sound card. card count=0 now
BUT alsa package have dummy sound card
it inserted into kernel as snd-dummy. so after i insert it into kernel i have cardcoutn=1
my qwestion is:
how i can insert enother and/or give parameters to kernel, so it will be 2 or more DUMMY card.
if u don't know what is dummy, read this
http://www.alsa-project.org/main/index.php/Matrix:Module-dummy
but actualy i need answer of someone who work with kernel modules, is it posible and how i can do it.

i can setup alias, i can setup dummy as sound card 2, or 3
but what i need is have more then 1 independed dummy card.
so i can setup 2 skype for different users on box, on different
dummy sound.
OK, I think you are asking if you can have only a single sound card,
and yet have it appear to alsa as if it is two separate cards. If that is
your question, the answer is no. The hardware can only process one
sound stream at a time (depending on the device). If it has multiple DACs
it can process more than one, but alsa would already have defined that
for you, so since you are asking I am assuming it has a single DAC for output.
It seems you want to have different sound streams use
the same card. You should be able to do what you want using either jack
or pulseaudio. This doesn't provide you with independent streams, they
are still related in time, so if they overlap you will hear both sounds at the
same time.
You could write an application that would isolate the separate sound
streams and send them to the sound card in sequence to do what you want,
with some delay when both users were using the sound card at the same time.
And as far as helping you with jack or pulseaudio, my knowledge doesn't extend
there.
