Unity not playing audio

My game audio isn't playing. It was earlier and then I made changes to my audio script, but it should be playing. I don't know what's happening. I even went back to my old script for it and it didn't work

 using UnityEngine;
 using System;
 using UnityEngine.Audio;
 
 public enum SoundTypes { ALL, SFX, MUSIC}
 
 public class AudioManager : MonoBehaviour
 {
 
     public float masterVolume, musicVolume, sfxVolume;
 
     public Sound[] music;
     public Sound[] sfx;
 
     public static AudioManager instance;
 
     void Awake()
     {
         if(instance == null)
             instance = this;
         else 
         {
             Destroy(gameObject);
             return;
         }
 
         DontDestroyOnLoad(gameObject);
 
         foreach (Sound s in music) 
         {
             s.source = gameObject.AddComponent<AudioSource>();
             s.source.clip = s.clip;
 
             s.source.volume = s.volume;
             s.source.pitch = s.pitch;
             s.source.loop = s.loop;
         }
 
         foreach (Sound s in sfx) 
         {
             s.source = gameObject.AddComponent<AudioSource>();
             s.source.clip = s.clip;
 
             s.source.volume = s.volume;
             s.source.pitch = s.pitch;
             s.source.loop = s.loop;
         }
     }
 
     void Start()
     {
         masterVolume = 1;
         musicVolume = 1;
         sfxVolume = 1;
         Play("MainMenu");
     }
 
     public void Play(string name) 
     {
         Sound m = Array.Find(music, sound => sound.name == name);
         if(m != null) 
             m.source.Play();
         else if ((m = Array.Find(sfx, sound => sound.name == name)) != null)
             m.source.Play();
     }
 
     public void ChangeVolume (SoundTypes type, float newVolume) 
     {
         if (type == SoundTypes.ALL)
             masterVolume = newVolume;
         else if (type == SoundTypes.MUSIC)
             musicVolume = newVolume;
         else if (type == SoundTypes.SFX)
             sfxVolume = newVolume;
 
         foreach (Sound s in sfx)
                 s.source.volume = masterVolume * sfxVolume;
         foreach (Sound s in music)
             s.source.volume = masterVolume * musicVolume;
     }
 }
