WAV sound effect is looped although Loop is not checked

[BorisBrock]

Godot version:
3.2.3 stable

OS/device including version:
Windows 10 20H2, x64, GLES2

Issue description:
When I call play() once on a AudioStreamPlayer3D, the sound keeps looping endlessly. I already checked in the sound's import settings that Loop is not enabled.

Steps to reproduce:
Create new project
Add .wav file, make sure Loop is not enabled in import settings
Add AudioSteamPlayer3D and assign the .wav to it
Call play() once on the audio stream player
-> Sound is looped endlessly

Minimal reproduction project:
SoundTest.zip

Did you reimport the resource after checking that looping is disabled in the Import dock?

Loop was disabled from the beginning. But I explicitly enabled it, then disabled it and re-imported again.

I think this has something to do with this particular wav file. If you import into audacity and re-export, the problem goes away. Also, adding this line makes the problem go away as well: $AudioStreamPlayer3D.stream.loop_mode = 0.

Maybe this is an issue with the loop point defined in the WAV file? Godot reads this loop point and sets it automatically. You can see the assigned loop point value by selecting the WAV file in the FileSystem dock then going to the Import dock.

Well, would it be possible to just ignore the loop points? I would love to have a way to loop the sound with loop points and play a sound from start without looping.

After importing the WAV file, you should be able to set the loop point to 0 manually in the Import dock and click Reimport.

Well, I would love to have both, the ability to loop between loop points and also the ability to play only once without changing the loop points.

To clarify about this which seems to confuse many users (I agree the UX is bad), here's what is happening:

• The WAV format has support for metadata that defines whether the sample should loop, and if so the start and end loop points. Godot's WAV importer imports these metadata by default.
• The "Edit > Loop" import option for WAV can be used to force loop on, but not to disable it. It should likely be changed to an enum (Detect, On, Off). Currently it's basically just (Detect, On).
• Imported resources cannot be edited by default, so changing the Stream > Loop Mode property doesn't actually work. That's why it says "Changes may be lost!" (see screenshot below). You can work this around by saving the Stream as a resource (Save As > name.tres), which can then be modified. This can let you force Loop off.
• As per the first point, another option is to edit the WAV file with an audio editor that supports WAV metadata to disable its built-in loop hints.

I tried re importing with Loop checkbox unchecked. Did not work. Tried checking, reimport, uncheck and re import again. Did not work

Tried setting Loop Mode to Disabled in the inspector, didn't work as well.

I'm using an AudioStreamPlayer and doing AudioStreamPlayer.stream.loop = false has worked for me 😄 .

Reading @akien-mga's comment makes me think this should be described in the docs. Maybe it is, I just haven't found it.
