it seems like you are using the "PA" acronym for different things.
Pd has a PortAudio backend (s_audio_pa.c), but afaik this does not
involve any service/daemon/programm which could be refered to with "and
magically PA starts".

there is PulseAudio on linux, which can be used via the PortAudio
backend, but afaiu you are on osx so i don't think that this applies.

i don't think it is off-topic, but probably more interesting for pd-list
(rather than pd-dev), as it is no more development-specific than any
other bug and more people could share there experiences.

therefore i'm answering via pd-list...
