Not specific to the subjet line but...
Is/are your patch(es) 'gui-heavy', which in Pd would be e.g. lots of
bangs or changing number-boxes? That in my experience has been cause of
audio drop-outs. Also make sure to run pd with the -rt flag and if you
are on a laptop make sure to disable WiFi.
Knowing more about the patch(es) is always very useful when trying to
debug Pd IMHO :-)
