UnityWebRequestMultimedia.GetAudioClip dont't work in WebGL build (2019.3.15f1).

Hello everyone,

I tried to use the sample of code here to request an audio file in WebGL build (in 2019.3.15f1).

https://docs.unity3d.com/ScriptReference/Networking.UnityWebRequestMultimedia.GetAudioClip.html

But only Wav files work, and Mp3 or OGG fail to load. I have read the limitation on my browser (Firefox) and normaly it support all this formats, but i alwais get

Streaming of 'ogg' on this platform is not supported.

Or mpeg.

How can I read compressed audio from SteamingAssets Folder ? Thanks in advance.

Here the code i use:

     using System;
     using System.Collections;
     using System.Collections.Generic;
     using UnityEngine;
     using UnityEngine.Networking;
     
     public class AudioRequest
     {
         public AudioClip audioClip = null;
     
         public IEnumerator SendGetAudio(string url)
         {
             using (UnityWebRequest www = UnityWebRequestMultimedia.GetAudioClip(url, AudioType.WAV))
             {
                 yield return www.SendWebRequest();
     
                 if (www.isNetworkError || www.isHttpError)
                 {
                     throw new Exception(www.error + "\n" + url);
                 }
                 else
                 {
                     audioClip = DownloadHandlerAudioClip.GetContent(www);
                 }
             }
         }
     }
