Hmm, ok, point taken, although I do not agree fully with all of your
reasoning. I still have to find the time to reintroduce the working
version s_alsa.c in a recent pd version. If someone wants to give it
a try, just take s_alsa from the devel_0_36 branch and adapt it
to pd 0.37 changed audio structure.
As long as I don't have a HDSP card I might not find the motivation
to do so. I am sorry, I am terribly lazy :(
