.produce audio not firing up

Hello, my .produce event listener is firing up only on video and not on audio even though I am passing audio and video for the .produce function.

async function loadDevice(routerRtpCapabilities) {
  try {
    device = new mediasoup.Device();
  } catch (error) {
    if (error.name === "UnsupportedError") {
      console.error("browser not supported");
    }
  }
  await device.load({ routerRtpCapabilities });
}

async function publish(e) {

  const data = await socket.request("createProducerTransport", {
    forceTcp: false,
    rtpCapabilities: device.rtpCapabilities,
  });

  const transport = device.createSendTransport(data);
  transport.on("connect", async ({ dtlsParameters }, callback, errback) => {
    socket
      .request("connectProducerTransport", { dtlsParameters })
      .then(callback)
      .catch(errback);
  });

  transport.on(
    "produce",
    async ({ kind, rtpParameters }, callback, errback) => {
      try {
        console.log("Kind:", kind);
      } catch (err) {
        errback(err);
      }
    }
  );

  let stream;
  try {
    stream = await getUserMedia(transport, isWebcam);
    console.log("getusermedia stream:");
    console.log(stream);
    const track = stream.getVideoTracks()[0];
    const track2 = stream.getAudioTracks()[0]; //audio
    const params = { track };
    const params2 = { track2 };
    console.log("tracks:");
    console.log(track); //outputs correctly
    console.log(track2); //outputs correctly


    producer = await transport.produce(params);  //gets a callback
    producer2 = await transport.produce(params2);  //doesnt get a callback
  } catch (err) {

  }
}

You are not even calling the callback
