Okay, one step closer. I somewhat randomly guessed to use NBExternalAddress,
but didn't have the correct thing in the signature...

So you're saying the signature would become:
�� nbCall: #(PaError Pa_OpenDefaultStream(NBExternalAddress * stream,
�� ...
�� ulong �� framesPerBuffer,
�� nil,
�� void * ��userData))

I made the changes as I understood them, but I'm getting a "generic failure"
when I call Pa_OpenDefaultStream.

I uploaded the latest changes to the repo...

sorry for late reply.

hmm.. everything should work.

except i think nil -> void * is not accepted by default.

you should use #optCoerceNilToNull option:

self nbCall: ... options: #(+ optCoerceNilToNull)

��

or, if you don't wanna mess with options, you can always pass a null pointer by constructing it,

a simplest way is to pass dumb and stupid

NBExternalAddress null.
