How to make player death sound effect / hitsound play once when function is called?

Hello, my player keeps looping their death sound / hit sound when they die in game I was wondering how I could make the player death / hit sound only play once. Right now its playing the death / hit sound but it is looping and overlapping rapidly and it's quite unpleasant to listen to.

    private bool alreadyPlayed;
             public AudioClip SoundToPlay;
             public float Volume;
     
     
     void Die()
     {
         charController.GetComponent<CharacterController>().enabled = false;
         GetComponent<AudioSource>().PlayOneShot(SoundToPlay, Volume);
             alreadyPlayed = true;
             gameOverScreen.SetActive(true);
         
         Debug.Log("You Have Died");
         GetComponent<AudioSource>().Stop();
 
         //do something here!
         /*GameObject[] enemies = GameObject.FindGameObjectsWithTag("Enemy");
             foreach (GameObject enemy in enemies)
             {
                 NavMeshAgent agent = enemy.GetComponent<NavMeshAgent>();
                 if (!agent)
                     continue;
                 agent.Stop(); */
 
             
 
         }
