Hi, I need to use external sound card on Windows, but I can't select it in jupyter notebook for some reason. When I'm running python -m sounddevice in the anaconda console on Windows 10 it gives me

But when sd.query_devices() in the jupyter notebook on the same machine gives me only

Running the same notebook in VS Code gives me full list of devices, so it looks like some Windows permissions issue and not the library, so I'll close it
