audio plays sometimes, then not others.

hi! My team is developing our first game for a game jam, that being a dungeon platformer, and we ran into a problem with our death sound. whenever we hit the spikes in the game, it plays. but when another sound plays like the coin sound, (which is just a bleep) it just doesn't play unless we wait.

any fix to this?

here's my player controller code if needed(sorry if it's messy, I'm both new to this, and in a hurry for the jam.)

 using UnityEngine;
 using System.Collections;
 using UnityEngine.SceneManagement;
 using TMPro;
 
 public class PlayerController2D : MonoBehaviour 
 {
 
 //Public Variables
     public float speed;
     public float jump;
 
     public float coinCount;
 
     public string currentScene;
 
     public string nextScene;
 
     public GameObject openDoor;
 
     public GameObject closedDoor;
 
     public GameObject doorTrigger;
 
     public TextMeshProUGUI countText;
 
     public AudioSource audioSource;
 
     public AudioClip JumpSound;
 
     public AudioClip collectSound;
 
     public AudioClip deathSound;
 
     public AudioClip doorOpenSound;
 
     //Private Variables
     private float moveVelocity;
     private bool grounded = true;
 
     void Start()
     {
         openDoor.gameObject.SetActive(false);
         doorTrigger.gameObject.SetActive(false);
 
         
 
         SetCountText();
     }
 
     void SetCountText()
     {
         countText.text = "Coins left: " + coinCount.ToString();
 
     }
 
     void Update () 
     {
         //Jumping
         if (Input.GetKeyDown (KeyCode.Space) || Input.GetKeyDown (KeyCode.UpArrow) || Input.GetKeyDown (KeyCode.Z) || Input.GetKeyDown (KeyCode.W)) 
         {
             if(grounded)
             {
                 GetComponent<Rigidbody2D> ().velocity = new Vector2 (GetComponent<Rigidbody2D> ().velocity.x, jump);
                 audioSource.PlayOneShot(JumpSound);
             }
         }
 
         moveVelocity = 0;
 
         //Left Right Movement
         if (Input.GetKey (KeyCode.LeftArrow) || Input.GetKey (KeyCode.A)) 
         {
             moveVelocity = -speed;
         }
         if (Input.GetKey (KeyCode.RightArrow) || Input.GetKey (KeyCode.D)) 
         {
             moveVelocity = speed;
         }
 
         GetComponent<Rigidbody2D> ().velocity = new Vector2 (moveVelocity, GetComponent<Rigidbody2D> ().velocity.y);
 
     }
     //Check if Grounded
     void OnCollisionEnter2D()
     {
         grounded = true;
     }
     void OnCollisionExit2D()
     {
         grounded = false;
     }
 
     //sets trigger functions in scene
    void OnTriggerEnter2D(Collider2D other)
     {
         if(other.gameObject.CompareTag("Pickup"))
         {
             other.gameObject.SetActive(false);
             coinCount -= 1;
             audioSource.PlayOneShot(collectSound);
 
             SetCountText();
 
             if(coinCount == 0)
             {
                 openDoor.gameObject.SetActive(true);
                 closedDoor.gameObject.SetActive(false);
                 doorTrigger.gameObject.SetActive(true);
                 audioSource.PlayOneShot(doorOpenSound);
             }
         }
         if(other.gameObject.CompareTag("Death"))
         {
             audioSource.PlayOneShot(deathSound);
             gameObject.SetActive(false);
             SceneManager.LoadScene(currentScene);
             
 
         }
 
         if(other.gameObject.CompareTag("DoorTrigger"))
         {
             SceneManager.LoadScene(nextScene);
         }
 
     }
