const d = document;
export function alarm(sound, btnPlay, btnStop) {
  let alarmTempo;
  const $alarm = d.createElement("audio");
  $alarm.src = sound;

  d.addEventListener("click", e => {
    if(e.target.matches(btnPlay)){
      alarmTempo = setTimeout(() => {
        $alarm.play();
      }, 2000);

      e.target.disabled = true;
    }

    if(e.target.matches(btnStop)){
      clearTimeout(alarmTempo);
      $alarm.pause();
      $alarm.currentTime = 0;
      d.querySelector(btnPlay).disabled = false;
    }
  });
}

My code is even bigger and i have a document js index where i imported all my function, but this is the part of the problem, in the function alarm(sound, btnPlay, btnStop), sound is a mp3 audio, btnPlay is a button with the id="activar-alarma" and btnStop is a button with the id="desactivar-alarma", a little help please :C.
