my sound clip reference is lagging playmode

Hello Community, got this 2d plataformer, and the character is a vehicule, so Im using addforce to move it. i could swear it was working fine. but I dont know what happened now it lags when I press the horizontal axis keys. starts fine, after some seconds starts to lag untill it freezes, if I release the movement keys the game returns to be fine, but as soon as I press the either key (left or right) again it lags. If I just move by pressing the boost button the game is totaly fine. If I press the boost button when using the movement keys, the character just flys of the screen super fast like it had stored force in it. help please, I have modified the script several ways and couldnt fix it. this is the C# code:

using System.Collections; using System.Collections.Generic; using UnityEngine;

public class PlayerStouss : MonoBehaviour {

public float speed = 6f , maxVelocity = 8f; private Rigidbody2D myBody; private Animator anim; private float volLowRange = 0.5f; private float volHighRange = 1.0f; void Awake () { myBody = GetComponent (); anim = GetComponent (); } // Use this for initialization void Start () { }

// Update is called once per frame void Update () {

} void FixedUpdate(){ // this gets the imput of the player to jump PlayerMoveKeyboard ();{ if (Input.GetButtonDown ("Jump")) Nitrous (); } } // this gets the imput for movement void PlayerMoveKeyboard(){ float forceX = 0f; float vel = Mathf.Abs (myBody.velocity.x); float h = Input.GetAxisRaw ("Horizontal");

  if (h > 0) {
      if (vel < maxVelocity)
          forceX = speed;
      Vector3 temp = transform.localScale;
      temp.x = 1f;
          transform.localScale =temp;
                  
      anim.SetBool ("StoussMoving", true);
      SoundManagerScript.PlaySound("StoussMoving");
              }
  else if (h < 0) {
      if (vel < maxVelocity)
          forceX = -speed;
      Vector3 temp = transform.localScale;
      temp.x = -1f;
          transform.localScale = temp;
      
      anim.SetBool ("StoussMoving", true);
      SoundManagerScript.PlaySound("StoussMoving");
  } 
  else
      anim.SetBool ("StoussMoving", false);
      myBody.AddForce (new Vector2 (forceX, 0));
  }

void Nitrous () {

  SoundManagerScript.PlaySound("StoussBoost");
  if (transform.localScale.x > 0)
      myBody.AddForce (transform.right * 8, ForceMode2D.Impulse);
  
      //myBody.AddForce (transform.up * 1 , ForceMode2D.Impulse);
  
   if (transform.localScale.x < 0)
      myBody.AddForce (transform.right * -8, ForceMode2D.Impulse);
              //myBody.AddForce (transform.up * 1 , ForceMode2D.Impulse);

}

}

guys I found Out that the culprit was this part :

SoundManagerScript.PlaySound("StoussMoving")

now I dont know how to fix it. is it that that sound is to heavy (2.9megabites)? or Am I implementing it in a bad way? this is the soundmangaer code:

using System.Collections; using System.Collections.Generic; using UnityEngine;

public class SoundManagerScript : MonoBehaviour {

 public static AudioClip StoussMoving, StoussShooting, StoussBoost, StoussBraking, StoussHit, StoussDeath;
 static AudioSource audioSrc;


 void Start () {
     StoussMoving = Resources.Load <AudioClip> ( "StoussMoving");
     StoussShooting = Resources.Load <AudioClip> ( "StoussShooting");
     StoussBoost = Resources.Load <AudioClip> ( "StoussBoost");
     StoussBraking = Resources.Load <AudioClip> ( "StoussBraking");
     StoussHit = Resources.Load <AudioClip> ( "StoussHit");
     StoussDeath = Resources.Load <AudioClip> ( "StoussDeath");

     audioSrc = GetComponent <AudioSource> ();
 }
 
 // Update is called once per frame
 void Update () {
     
 }

 public static void PlaySound (string clip){
 
     switch (clip) {

     case "StoussMoving":
         audioSrc.PlayOneShot (StoussMoving);
         break;

     case "StoussShooting":
         audioSrc.PlayOneShot (StoussShooting);
         break;

     case "StoussBoost":
         audioSrc.PlayOneShot (StoussBoost);
         break;
     case "StoussBraking":
         audioSrc.PlayOneShot (StoussBraking);
         break;
     case "StoussHit":
         audioSrc.PlayOneShot (StoussHit);
         break;

     case "StoussDeath":
         audioSrc.PlayOneShot (StoussDeath);
         break;
     }

 }

}
