does it now work with Pd/ALSA ?

if you need jack, you have to provide more info: Pd's jack backend is 
far from perfect and there have been several attempts to make it work, 
which means, that different versions (and flavours) of Pd will behave 
differently. which one are you using?

Pd-vanilla at least will not startup a jackd automatically, so jackd has 
to be running before you start to Pd (or switch to jack).
also note that switching audio-apis might work less than starting Pd 
with the correct API from the beginning.
e.g. use something like "pd -jack -channels 8"
