Perhaps you forgot to add -Q0 -+rtmidi=null to the command line options ?
Replace the '0' with any device name and it will be passed to the open
callback.

Does it actually print other information about the file (sample rate,
length, etc.) ? If yes, then the SD2 format is possibly just not
included in the table of file format names, and that is why "unknown"
is printed. Otherwise, any problems are probably in libsndfile.

The filepeak opcode was disabled while moving to use libsndfile. It will
be restored, although it may not behave exactly the same way: the old
version did not return a peak value if the header did not include such
information, while libsndfile would scan the entire file then which may
take a long time. Hopefully libsndfile does use the peak chunk when it
is present.

Utilities currently do not support graphs; may be implemented later.

No idea about whay that happens. The files should be deleted when
csoundReset() is called, and it does work for me.

Do you mean these problems occur with the rtaudio modules that come
with the canonical release (if so, more reports from other Mac users
could be useful) ?
Or do you have problems implementing real time audio using the API,
overriding the default code ?

Is chdir() not sufficient for this purpose ?
