I can confirm that the workaround works on macOS 12.6 & arm64 if cffi and sounddevice are installed using pip.

Making statements based on opinion; back them up with references or personal experience. That was the best I could think of without breaking the API.) This routing would probably need some kind of global lookup table on the Python-side for each usage of ffi.callback. Why does Q1 turn on and Q2 turn off when I apply 5 V?
