Question

I'm trying to play sound file, downloaded with WWW class. Here is the code:

 using UnityEngine;
 using System.Collections;
 
 public class audio : MonoBehaviour
 {
     AudioSource source;
     // Use this for initialization
     void Start()
     {
         source = GetComponent<AudioSource>();
         StartCoroutine(StartAudio());
     }
 
     IEnumerator StartAudio()
     {
         WWW audioLoader = new WWW("file://E:/Music/sample.wav");
         AudioClip a_clip = audioLoader.audioClip;
 
         while (!a_clip.isReadyToPlay)
             yield return audioLoader;
 
         source.clip = audioLoader.GetAudioClip(false);
         source.Play();
 
     }
 }

When I run the project, sound don't play and I get error without text: error

I have tried to delete all preferences and reinstall Unity, but it doesn't help. I'm really don't know what to do =(

Answer 1

that's indicative of unity not finding your URL.

this code works for reading from a web server or local file system. it plays any sound currently set up (to ensure the audio source is working properly...)

 using UnityEngine;
 using System;
 using System.Collections;
 
 public class Loader : MonoBehaviour
 {
     private AudioSource _audioSource;
 
     private string _audioURL = "www.yourDomainHere.com/filename.wav";
     //private string _audioURL = "file:///Users/yourNameHere/Dropbox/filename.wav";
 
     //
     public void Start()
     {
         _audioSource = GetComponent<AudioSource>();
         if (_audioSource == null)
         {
             Debug.Log("No AudioSource component found!");
         }
         else
         {
             if (_audioSource.clip != null)
             {
                 _audioSource.Play();
             }
 
             StartCoroutine(LoadAudioClip(_audioURL));
         }
     }
 
     //
     private IEnumerator LoadAudioClip(string audioURL)
     {
         Debug.Log("Loading clip from WWW");
 
         var audioLoader = new WWW(audioURL);
         var clip = audioLoader.audioClip;
 
         yield return new WaitUntil(() => clip.loadState.Equals(AudioDataLoadState.Loaded));
 
         if (clip.loadState.Equals(AudioDataLoadState.Loaded))
         {
             _audioSource.clip = audioLoader.GetAudioClip(false, false);
 
             Debug.Log("Playing clip...");
             _audioSource.Play();
         }
     }
 }
