I get the Bird Foot Steps sound but not the Player Movement Sounds.

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


public class RandomSoundPlayer : MonoBehaviour {

    private AudioSource audioSource;

    [SerializeField]
    private List<AudioClip> soundClips = new List<AudioClip> () ;

    [SerializeField]
    private float soundTimerDelay =3f;
    private float soundTimer;

    // Use this for initialization
    void Start () {
        audioSource = GetComponent<AudioSource> ();

    }

    // Update is called once per frame
    void FixedUpdate () {
        //Increment a timer to count up to restarting
        soundTimer = soundTimer + Time.deltaTime;
        if (soundTimer >= soundTimerDelay) {

        // ... reset the timer ...
            soundTimer = 0f;

        //... choose a random sound...
            AudioClip randomSound = soundClips[Random.Range (0,soundClips.Count-1)];

        //... and play the sound.
            audioSource.PlayOneShot (randomSound);


        }

    }
}
