You’re not passing the timeout a function. It needs to say:

setTimeout(
  () => alert("Totaler Absturz. Score: " + Math.floor(counter / 100)),
  5000
);

It’s the () => ... bit that will wrap your alert in a function. If it’s not wrapped in a function, it will execute immediately.

I need a sound to play while or before a score alert pops up (simple dinosaur game). Right now it just shows the alert and then it plays the sound. I have tried to set a timeout but it doesn’t work.

if (blockLeft < 200 && blockLeft > 0 && characterTop >= 300) {
    const death = new Audio((URL = "/sound/death.mp3"));
    death.play();
    death.volume = 0.4;
    block.style.animation = "none";
    block.style.display = "none";
    setTimeout(
      alert("Totaler Absturz. Score: " + Math.floor(counter / 100)),
      5000
    );
    counter = 0;
}
