Windows beeps when Num Lock changes during a game: identify Toggle Keys
When the same short tone plays each time you press Num Lock during a card game, compare it with the sound outside the game. Use a safe screen with no chat or account form focused.
What to check
Microsoft says Toggle Keys can produce a sound when Caps Lock, Num Lock or Scroll Lock changes. Check Accessibility > Keyboard for its current state. Some people rely on the sound as feedback, so preserve the setting while checking the cause.
Compare one example
If the tone repeats when you press the same key outside the game, note the Windows behavior separately from game audio. If multiple ordinary keys trigger different sounds only on one game screen, check that game’s documented controls and audio options.
