How to record audio with python sounddevice on WSL?

Question

I am on WSL, and when trying to record audio using sounddevice, I get an error saying no device was found: sounddevice.PortAudioError: Error querying device -1.

I followed sounddevice's instructions and installed libportaudio2, CFFI, and numpy.

I also followed PortAudio's instructions and compiled PortAudio.

As my device is a USB microphone, I also followed this to attach the device to WSL, apparently successfully as when I run usbipd wsl list in Windows Powershell I get:

BUSID  VID:PID    DEVICE                                                        STATE
1-2    239d:f218  USB Input Device                                              Not attached
1-3    216e:2462  Camera                                                        Not attached
1-6    046d:0a38  Logi USB Headset H340, USB Input Device                       Attached - WSL
1-10   12s1:8543  Bluetooth Adapter                                             Not attached

and when I run sudo usbip port in the WSL bash I get:

Port 00: <Port in Use> at Full Speed(12Mbps)
       Logitech, Inc. : Headset H340 (046d:0a38)
       1-1 -> usbip://172.25.96.1:3240/1-6
           -> remote bus/dev 001/006

And yet, when my python script calls sounddevice.rec I get the following:

Traceback (most recent call last):
  File "/home/user/project/scripts/recorder.py", line 223, in <module>
    main()
  File "/home/user/project/scripts/recorder.py", line 203, in main
    recording = record(args.sample_rate, args.duration)
  File "/home/user/project/scripts/recorder.py", line 54, in record
    recording = sd.rec(int(duration * sample_rate), samplerate=sample_rate, channels=2)

  File "/home/user/project/venv/lib/python3.9/site-packages/sounddevice.py", line 817, in __init__

  File "/home/user/project/venv/lib/python3.9/site-packages/sounddevice.py", line 2660, in _get_stream_parameters
    info = query_devices(device)
  File "/home/user/project/venv/lib/python3.9/site-packages/sounddevice.py", line 569, in query_devices
    raise PortAudioError(f'Error querying device {device}')
sounddevice.PortAudioError: Error querying device -1

Also, running python3 -m sounddevice in the terminal or sd.query_devices() in the console return nothing.

What am I missing here? Is there a way to make it work?
