Beep sound when starting DbD?

Irisora

Hi, for some reason im hearing a beep sound when starting dbd anyone knows why? It plays at starting and stop, not a problem, but im curious.

Edit: I managed to solve it, it was caused by the new radeon anti-lag setting in my graphic card. It was just causing that beep sound, but i prefer to switch it off to prevent breaking something, and leave this to anyone that have the same issue and to let devs know if it's a bug or something.
