Maybe you can try this,

let videoConstraints = {
     height: { min: 640, ideal: 1920, max: 1920 },
     width: { min: 400, ideal: 1080 },
     frameRate: { max: 30 }
   };

let audioConstraints = {
    channelCount: 1,
    sampleRate: <YOUR VALUE>,
    sampleSize: <YOUR VALUE>,
    volume: 1,
    latency: 0.003,
    echoCancellation: true,
    noiseSuppression: true,
    autoGainControl: true,
  };
  constraints = { audio: audioConstraints, video: videoConstraints };

Usage,

navigator.mediaDevices
      .getUserMedia(constraints)
