Begin by dragging and dropping your sound file into the assets folder. For example, in this scenario, we've dragged a sound file that plays when the player wins.

After that, drag the audio clip from the assets folder into the effects list within the sounds manager.

private void OnTriggerEnter2D(Collider2D collision)
{
    if (collision.tag == "win")
    {
        winPanel.SetActive(true);
        SoundManager.instance.PlayEffect(1);
    }
}

In this Unity script, the OnTriggerEnter2D method is used to detect when a game object with a 2D collider enters a trigger zone. If the object has a tag labeled "win", the script activates a UI element called winPanel to display a winning message or screen. Simultaneously, it calls the PlayEffect method from the SoundManager singleton instance to play a sound effect. The sound effect played is the one located at index 1 in the sound manager's effects list, which is typically pre-configured in the Unity editor.

You can add more sound effects with this way, and everything will work perfectly.
