winapi - Redirect audio output to input stream - python-sounddevice

Question

I'm using the sounddevice library for Python. So far I was able to do some basic stuff with audio files through this library, like playing back a WAV format file using this code from one of the tutorials:

#!/usr/bin/env python3
import sounddevice as sd
import soundfile as sf

try:
    data, fs = sf.read('[path to audio file]', dtype='float32')
    sd.play(data, fs, device=None)
    status = sd.wait()
except KeyboardInterrupt:
    print("Keyboard interrupt")
except Exception as e:
    print("Internal exception")

However, I need to redirect that audio output to the system's microphone input instead of the speakers, and I'm not sure how to do that with this library since there isn't a lot of clear documentation on this. Is there a way to do this with sounddevice? I would like to avoid directly interacting with the OS sound drivers, since ideally this should be cross-platform.

Thanks!

Edit: It seems like it's not possible to make this fully cross-platform, so ideally I would like to be able to use this with Windows and the WSAPI.
