Issue description

AudioStreamPlayers don't emit the finished signal after playing a stream from an Audio Playback track.

Steps to reproduce

Add an animation with an Audio Playback track. Connect the AudioStreamPlayer's finished signal to a method in a script, and do a print()

AudioTrack uses AudioStreamPolyphonyc rather than a single AudioStream, so it is necessary to monitor the AudioStreams within AudioStreamPlaybackPolyphonic. (The method to get the currently playing stream may not be implemented yet...?)

On 4.2 I face the same issue. Running with v4.3.dev (master) resolves this issue for me.

This seems to be a duplicate issue:

AudioStreamPlaybackPolyphonic doesn't emit finished signal for each AudioStream

Afaik this is a design choice: finish will be emitted only after the very last AudioStream finished.

And this concern is already tracked here: #75089

[…] neither allow get the reference from ID

This sounds a bit too vague. But I reckon this fixes your concern: #86054 ?

@Domeee: The stream IDs you get all work? So #86054 is not necessary anymore?

@Domeee: reminder for my previous comment. The feedback would be much appreciated!

@MJacred As far as I can tell, all stream IDs work. I instantiate a bunch of AudioStreamPlayer in _ready which are then used in a queue to play all sorts of sfxs. If I would not get all finishedevents, I would run ouf of players very fast. This was the case in 4.2 and is resolved in 4.3.dev. HTH
