Tested versions

Reproducible in 4.3.stable.official [77dcf97d8]. Not reproducible before 4.3 as AudioStreamInteractive did not exist.

System information

Godot v4.3.stable - Windows 10.0.22631 - Vulkan (Forward+) - dedicated AMD Radeon RX 6600 (Advanced Micro Devices, Inc.; 32.0.11037.4004) - AMD Ryzen 5 5600X 6-Core Processor (12 Threads)

Issue description

When using AudioStreamInteractive, AudioStreamPlayer.get_playback_position() always returns 0 instead of returning the actual position. This is true for mp3 files and wav files, and probably other formats.

Steps to reproduce

  1. Create new project.
  2. Create AudioStreamPlayer node.
  3. Set AudioStreamPlayer's stream to AudioStreamInteractive
  4. Expand the AudioStreamInteractive in the inspector.
  5. Add clip.
  6. Import any audio file to the project.
  7. Set Clip 0's stream as the new audio file (drag the audio file over Clip 0's stream)
  8. Attach a script to the AudioStreamPlayer node.
  9. Replace function _process() with the following: func _process(delta: float) -> void: print(get_playback_position())
  10. Run project and see that the result is always 0.

Minimal reproduction project (MRP)

In my MRP, I have included a 2-second mp3 of my own creation. I've set the mp3 to loop to demonstrate the bug clearly, but the bug also happens if the loop is disabled. audiostreaminteractive-bug-test.zip

I'm wondering if this is actually a bug. If there's multiple tracks, what does the playback position actually mean? Especially if there's long transitions.

That does sound very reasonable. In that case, is this something to document instead? Neither the documentation of AudioStreamInteractive nor AudioStreamPlayer mentiones that get_playback_position() always returns 0 when using AudioStreamInteractive. I could make a PR that adds this to the documentation if that sounds good.

Sounds great! Feel free to close this PR and mention it in your documentation one.
