PPC Linux and PD

As I am the person trying to adapt s_linux.c to the new ALSA I can say the
only thing that I was thinking of changing outside of the existing alsa
functions is making the sys_send_dacs function a pointer to a function set
in the respective open functions.  I am looking at four perspective ways
to write to a sound card under the new alsa (block and stream modes with
either ints of floats) so the current forest of ifs everytime you write to
the sound card would get a little out of control.  The good news is that
it is possible to write floats to sound cards that will accept them with
sample level accuracy . . . of course with no documentation it has been
fun figuring all of this out!  Maybe you should just tell me what you had
in mind.  Hopefully I will have something in another week or two - it is
floating back to the top of my list of things to do.
