[jlx-286]

Tested versions

• Reproducible in: v3.5.3.stable.mono.official [6c814135b] (Windows 10)
• Not reproducible in: v3.5.3.stable.mono.official [6c814135b] (Ubuntu 20.04),.NET 8 (Windows 10),.NET Core 3.0 (Windows 10),Unity 2018.4.13f1

System information

Windows 10,Ubuntu 20.04 - Godot v3.5.3.stable.mono

Issue description

part of the output in "cmd.exe" (but "audioplugin-fluidsynth-3.dll" works normally)

fluidsynth: error: Invalid chunk id in level 0 parse
fluidsynth: error: Failed to load SoundFont "TimGM6mb.sf2"

Steps to reproduce

• enable "fluidsynth command" if not enabled
  • download FluidSynth and "unzip"
  • add the directory of "libfluidsynth-3.dll" to "%path%"
  • reboot
• "run libfluidsynth"
  • run "Godot_v3.5.3-stable_mono_win64.exe" in "cmd.exe" or open "Godot_v3.5.3-stable_mono_win64_console.cmd"
  • "private const string PluginName = "libfluidsynth-3";" instead in the "166th" row of the script "https://github.com/jlx-286/lunatic-rave-3/blob/master/LR3_default(480p)/Scripts/FluidManager.cs or https://github.com/jlx-286/lunatic-rave-3/blob/master/LR3_WMIX(720p)/Assets/Scripts/FluidManager.cs"
  • play the (Godot) project
  • part of the output in "cmd.exe" (fluid_synth_sfload returns -1)

    fluidsynth: error: Invalid chunk id in level 0 parse
    fluidsynth: error: Failed to load SoundFont "TimGM6mb.sf2"

This sounds like something to report to the plugin, this is for the engine not third party content
