Anaconda: PyAudio install interferes with ASIO recognition

I just wasted a couple of days looking into this issue. It seems that the Pyaudio/Portaudio install interferes with the python-sounddevice query_devices() function for ASIO devices. No matter what I did I could not see my ASIO drivers when performing the python-sounddevice query_device(). Even after I installed python-sounddevice with PIP and verified that it was returning the ASIO enable Portaudio version libportaudio64bit.dll with the get_portaudio_version() function. It wasn’t until I removed Pyaudio/Portaudio from my Anaconda install that I could see my ASIO devices.

Q1: Do I have a need for pyaudio if I have python-sounddevice? Q2: Is there a way to make these work together?

Here is my python-sounddevice Python program: Sounddevice_DeviceQuery.py

import sounddevice as sd
print(sd.query_devices())
print(sd.get_portaudio_version())
print(sd.query_hostapis())

from ctypes.util import find_library
print(find_library('portaudio'))
print(find_library('libportaudio64bit'))

Thanks @neilser, that’s good to know.

The path containing _sounddevice_data shows that the pre-packaged library from _sounddevice_data is used.

When installing the library with conda, the path would be different.

I just ran into this issue. Is there a reason why the package available on pypi is able to include portaudio compiled with ASIO support built-in, but the conda version cannot? Does this have to do with the fact that the conda-forge feedstock recipe would need to include the SDK as part of the repo to enable the automated builds?
