Rigidbody and collision box issues.

I have put a box collider and a rigidbody to a bicycle avatar. And it is coming toward the camera which is the player and have a box collider and a rigidbody. It should have collision detection and have a sound when the bicycle pass through the camera(player). But no sound at all. Another collision is with the Destroyer which destroy the bicycle when collide with it. Please help my project.

  void OnCollisionEnter(Collision col)
 {

    if (col.gameObject.tag == "MYBICYCLE")
    {
        gg.BounceSound.Play();//AudioSource 
     if (col.gameObject.tag == "MYBICYCLE")
        {
        Destroy(col.gameObject);
        }
    }
}

This works for me…

 void Start()
 {
   mySound = gameObject.GetComponent<AudioSource>();
 }
    
 void stuff()
 {
   mySound.Play();
 }
