Summary: Driver for VIRTUAL/DUMMY card(s) that forward/mix to
real cards
Description:
As all sound devices can only be opened with exclusive access, and there
are quite a few close-source programs that interact with "/dev/dspX"
(OSS), would it be possible to have virtual cards that would mix to the
real one(s)?

Is there no interest for such a driver?
This would allow to use closed-source apps that just support old-style OSS
and don't work (correctly) over wrappers (some browser plugins, VMWare and
others). In addition it could be used to get rid of sound-daemons, using
dmix plugin and routing non-alsa apps through that virtual-pcm driver!
Use: same as for virtualmidi, but for PCMs!

I'm certainly interested in such a driver and would really love, when I'll
have some more free time, to go into the kernel programming neceesary for
it.
BTW, Charles Samuels (of Noatun fame) once tried writing something like
this (a driver that forwards sound to a user-space application which then
can do whatever it wants with it) but I don't know how well he fared.
