ok, finally i got his question - well, i didn't read carefully it
before, since i still have 5,000 unread mails...

anyway, it's possible if you use aoss wrapper and specify dmix/dsnoop
as the device.  you're right for the kernel emulation.  no way.
but still we need a fix for aoss wrapper.  the only necessary change
is to allow aoss open different pcm per playback and capture stream.

for example, the below is a minute quick hack (untested) for that.
you can specify pcm.dsp0p and pcm.dsp0c for playback and capture
directions, respectively.
