Footstep sounds system with a Vr touchpad movement system

Hello, i use the first person controller prefab from the Standard Unity Assets and modified the FirstpersonController Script by adding this code:

 if (GvrControllerInput.IsTouching)
             {
                 ddTouchpadPos = GvrControllerInput.TouchPos;
                 if (ddTouchpadPos.y < 0.5f - deadZone)
                 {
                     normalizedDDTouch = Vector3.ProjectOnPlane(cameraTransform.forward, Vector3.up) * 0.08f;
                 }
                 if (ddTouchpadPos.y > 0.5f + deadZone)
                 {
                     normalizedDDTouch = Vector3.ProjectOnPlane(cameraTransform.forward, Vector3.up) * -0.07f;
                 }
 
                 if (ddTouchpadPos.x < 0.5f - deadZone)
                 {
                     normalizedDDTouch = cameraTransform.right * -0.07f;
                 }
                 if (ddTouchpadPos.x > 0.5f + deadZone)
                 {
                     normalizedDDTouch = cameraTransform.right * 0.08f;
                 }
                 transform.localPosition += normalizedDDTouch;
           }

now i want to play sounds for every meter the character moves i dont get how the footstep system in this prefab works so it does not work for me can you please help me. Thank you anyways :) (Sry for my english)i have no animation for my character and no model

Footsteep System from the Prefab:

  private void ProgressStepCycle(float speed)
         {
             if (m_CharacterController.velocity.sqrMagnitude > 0 && (m_Input.x != 0 || m_Input.y != 0))
             {
                 m_StepCycle += (m_CharacterController.velocity.magnitude + (speed*(m_IsWalking ? 1f : m_RunstepLenghten)))*
                              Time.fixedDeltaTime;
             }
 
             if (!(m_StepCycle > m_NextStep))
             {
                 return;
             }
 
             m_NextStep = m_StepCycle + m_StepInterval;
 
             PlayFootStepAudio();
         }
 
 private void PlayFootStepAudio()
         {
             if (!m_CharacterController.isGrounded)
             {
                 return;
             }
             // pick & play a random footstep sound from the array,
             // excluding sound at index 0
             int n = Random.Range(1, m_FootstepSounds.Length);
             m_AudioSource.clip = m_FootstepSounds[n];
             m_AudioSource.PlayOneShot(m_AudioSource.clip);
             // move picked sound to index 0 so it's not picked next time
             m_FootstepSounds[n] = m_FootstepSounds[0];
             m_FootstepSounds[0] = m_AudioSource.clip;
         }

Edit: i read that there is no footstep sound in vr because thats annoying for users is that true?
