Is it possible to connect to Windows 10 WSL to the laptop microphone?

Question

I need to stream the laptop mic into the WSL environment. Install pulseAudio successfully on both windows and WSL - but my program still can't connect to the mic: (node program under WSL):

var record = require('node-record-lpcm16')
let stream = record.start({
    sampleRate: 16000,
    channels: 1,
    compress: false,
    threshold: 0.0001,
    thresholdStart: null,
    thresholdEnd: null,
    silence: '1.0',
    verbose: false
 })

ERROR IS
