HID SIGNO readers not beeping when admit

Hi all,

I have HID Signo reader on an iSTAR ultra and i set the lcd message set to beep when card is admitted. I also set the readers audio&visual to host controlled, but it does not beep. I also trued to configure the reader to beep in the reader manager application but atill nothing. What could go bad?

Thanks for the answers and recommendations.
