Select AudioStreamInteractive clip before playing a sound

housatic

I have an AudioSteamPlayer with an AudioStreamInteractive containing a bunch of clips. I want to select a clip and play it. In order to select a clip I first need to get the AudioStreamPlaybackInteractive. In order to get the playback I need to first play a sound...

E 0:00:02:765 NativeCalls.cs:518 @ Godot.GodotObject Godot.NativeCalls.godot_icall_0_59(nint, nint): Player is inactive. Call play() before requesting get_stream_playback().

If I check "Autoplay" on the player (or fire play()) then I don't get the error, but that (naturally) plays the first audio clip. But the first clip that I added in the editor isn't necessarily the first one that I want to play. I'm thinking I could pause or mute the audio it and then unmute it once the right clip is selected, but that feels like a hack...

Oh hey, Google showed me my own post from a year ago. Using the AudioStreamPlayer's parameters instead of calling SwitchToClip() on AudioStreamPlaybackInteractive avoids the error.

Set("parameters/switch_to_clip", "clip_name");
Play();

Though for some reason this now causes Play() to play two different clips (the initial clip + the selected clip) simultaneously. Should that even be possible when "Max Polyphony" is set to 1? I know it's coming from the same AudioStreamPlayer, both sounds get quieter when I lower its volume. And the second unwanted sound changes when I change "Initial Clip" in Remote.

After trying SwitchToClipByName() again it looks it doesn't do anything, it doesn't throw an error but only the initial clip plays and "Switch to Clip" is blank. So the same issue from the original post.

Created a blank project to test this out. When changing "switch_to_clip" the sound plays automatically, so calling Play() is unnecessary and just messes things up (though for some reason it behaves differently when using set() and switch_to_clip(), as described above). BUT this only seems to work if "Autoplay" is checked, which means the initial clip plays before I want it to... so I'm back at the original issue. The docs are pretty useless here: https://docs.godotengine.org/en/stable/classes/class_audiostreamplaybackinteractive.html

Okay, I'm not wasting any more time on this O_O I just set the AudioStreamPlayer volume to -80 dB, and set it back to 0 when I play the first sound. For some reason setting the volume too low also pauses the player, so I need to undo that too.

if (audioPlayer.StreamPaused)
{
    audioPlayer.StreamPaused = false;
    audioPlayer.VolumeDb = 0;
}

Hey there
I am facing the same problem, where multiple sounds are playing with the AudioStreamInteractive. However I think I found a feasable solution.

Use "Edit Transitions" (Inspector -> InteractiveStreamPlayer -> Edit Transitions

In the Row/Col of "AnyClip" -> "Any Clip" You could use the following (very simple solution)

Basically: Select Any Clip -> Any Clip and then:

"Use Transition" -> Enabled
Transition to the Start of the Audio Clip
Disable the "Fade Mode" (I still put Fade Beats to 0.0 just in case) and
disabled the filler Clip.

Edit:

I used a "Manager" to call the AudtioStreamPlayer after that and used part of your written solution

@onready var sounds : AudioStreamPlayer = $Sounds

## some other code

func _play_sound(soundName: String):
	self.sounds.set("parameters/switch_to_clip", soundName)
	self.sounds.play()
