Issue description

While I played wav sounds at Android, I found an weird issue, I have loaded the sounds by [Export], but if I don't check it has cache, it will result to FPS cliff, you can view the FPS line chart.
The program is play sound randomly. The only thing I did during this process was click the button, and I could see that the frame rate was very unstable.

But if I add ResourceLoader.HasCached, the FPS is stable 59 ~ 60.

    public override void _Ready()
    {
		  GD.Print("Scene Ready");
		  foreach (AudioStream audio in sounds)
		  {
			GD.Print("Audio" + audio.ResourceName + "is loaded:" + ResourceLoader.HasCached(audio.ResourcePath));
		  }
    }

Besides, while I use ogg sounds, it is no the issue, but I found the FPS flow during 59 and 60, I don't know the reason.
I use the online web for converting wav to ogg files: https://www.freeconvert.com/wav-to-ogg/download

Steps to reproduce

1. Create an C# script and add some wav resource to [Export] attributes.
2. play the above wav randomly.

Minimal reproduction project (MRP)

test_for_ogg.tscn is add ogg resources to [Export] attr.
test_for_wav.tscn is add wav resources to [Export] attr.
