AudioServer not working when I export to HTML

Godot Version

v4.3

Question

Hello! I’m making a rhythm game where I need to keep track of the song position and play a metronome.
Everything works as intended when I run the game locally on my computer, however, when I export it to HTML, AudioServer malfunctions and returns negative.

Weirdest of all, it visually works until I click on the browser to play my game. I also made sure to enable both thread and extension support!

var song_position: float = 0.0
var song_position_in_beats: float = 0
var last_reported_beat: float = 0
var seconds_per_beat: float = 0

func _process(delta: float) -> void:
	if music_player.playing:
		song_position = music_player.get_playback_position() + AudioServer.get_time_since_last_mix()
		song_position -= AudioServer.get_output_latency()
		song_position_in_beats = snapped(song_position / seconds_per_beat, 0.1) + beats_before_start

		label.text = str(song_position_in_beats)
		label_2.text = str(last_reported_beat)
		
		if not _repeating_beat():
			_change_color()
			
func _repeating_beat() -> bool:	
	if song_position_in_beats == last_reported_beat:
		return true
		
	last_reported_beat = song_position_in_beats	
	return false

AudioStreamPlayer.get_playback_position() is not work at godot 4.3 HTML5 export

It’s not a stable release, but you can use godot4.4-dev2 if you want use AudioStreamPlayer.get_playback_position()
