  well, this seems a good start nevertheless.

  I've just a little doubt. From what I've understood from the alsa-devel
list, it seems that the ALSA 0.5 has been declared dead almost officially.
They are not supporting it anymore, more over they are actively pushing
the new 0.9 interface and library. IIRC, they want to get out a rc1 next
week, or like.

  BTW, It's been quite a while that I'm using ALSA 0.9, so I can try to
port your code to it.

  I'm not so sure. It seems that the next versions of SuSE and Mandrake
will contain ALSA 0.9, I don't know Red Hat plans on this one, as well
as others' but I can check...

Strange game.
The only winning move
is not to play.
What about a nice play of chess ?
