Reproduction steps:

1. Open the attached project "Download Audio Crash".
2. Enter play mode.
3. Press spacebar.
4. Press backspace.

Expected: The editor doesn't crash and the editor throws an error. If using DestroyImmediate, the audio source should stop outputting sound.

Actual: The audio source continues outputting sound for a destroyed audio clip and the editor crashes after a few seconds.

{}Reproducible on{}: 2021.3.35f1, 2022.3.20f1, 2023.2.13f1, 2023.3.0b10

{}Reproduced on{}: Windows 10, Windows 11, MacOS (M1)

Note

• In the attached project "Download Audio Crash", you can change the Using Resources Load boolean to true on the game object script to test what happens if using that method instead.
• This error happens when using Resources.Load instead, and could be the expected results. However, the user can use DestroyImmediate to repro the error, so there should be a safe guard in place where the audio source is trying to play a clip that has been deleted.

Expected error:
{code:java}
Destroying assets is not permitted to avoid data loss.
If you really want to remove an asset use DestroyImmediate (theObject, true);
UnityEngine.Object:Destroy (UnityEngine.Object)
StreamAudio:Update () (at Assets/StreamAudio.cs:27) {code}

• If using Resources.Load and DestroyImmediate, the audio source actually stops outputting sound immediately when the clip is destroyed.
