WebGL: play audio from URL

Description:
I have an issue with playing audio from url on webgl platform.
First time audio is played OK, the next call to play audio crashes app with the following error dialog (complete log attached):


I tried to locate the problem and understand the error more and seems like it crashes on
this line

Code (CSharp):

1. AudioClip clip = DownloadHandlerAudioClip.GetContent(uwr)

I tried to find in the documentation any guideline on how to deal with audio on WebGL and I see some limitations mentioned but for me it still not clear is it possible to do or not?

Environment:
Unity 2021.3.1f1
Chrome Version 102.0.5005.61 (Official Build) (arm64)

Log:
Complete log of error

Code:

Code (CSharp):

1.         using (UnityWebRequest uwr = UnityWebRequestMultimedia.GetAudioClip(audioUrl, AudioType.MPEG)) {
2.        
3.             var response = uwr.SendWebRequest();
4.             yield return response;
5.             if (uwr.isNetworkError) {
6.                 Debug.Log(uwr.error);
7.             } else {
8.                 AudioClip clip = DownloadHandlerAudioClip.GetContent(uwr);
9.                 // Play audio clip logic
10.             }
11.         }

 

Do you cache the clip or download it every time it is played?

 

well its cached by server, its cached by browser, I don't see reason to cache one more time - yes I download it everytime for now

 

Just a few things I would try:

Can you play the downloaded clip twice in a sequence? (ie download it once, assign it to clip, then play clip twice - with or without waiting for the first playback to finish)

If that fails, can you play the same clip multiple times when the audio is embedded in the build?

Test it on a different machine and different browsers to check if the behaviour is consistent.

 

No, I think my problem is similar to this one. Currently tried to use this solution and it works but audio is distorted

 

I have figured out myself, this code works for me:

Code (CSharp):

1. using UnityWebRequest www = UnityWebRequestMultimedia.GetAudioClip(audioUrl, AudioType.MPEG);
2.         DownloadHandlerAudioClip dHA = new DownloadHandlerAudioClip(string.Empty, AudioType.MPEG);
3.         dHA.streamAudio = true;
4.         www.downloadHandler = dHA;
5.         www.SendWebRequest();
6.         while (www.downloadProgress < 1) {
7.             Debug.Log(www.downloadProgress);
8.             yield return new WaitForSeconds(.1f);
9.         }
10.         if (www.responseCode != 200 || www.result == UnityWebRequest.Result.ConnectionError) {
11.             Debug.Log("error");
12.         } else {
13.             audioSource.clip = DownloadHandlerAudioClip.GetContent(www);
14.             Debug.Log("Start audio play");
15.             audioSource.Play();
16.         }
