Arduino does not make any sound when connected to laptop? When I connect my Arduino through USB to my laptop, it does not make any sound like something is connected but green light is on. And port option in the Arduino IDE remains grayed out. I might have burned my Arduino, maybe? Please help.
The Arduino will not make a sound, but probably you refer to the sound Windows makes when a USB device is connected?

Try (except for the tips already given by JRobert)


different USB port
reinstall Arduino IDE
disable/enable or reinstall driver in Control panel/hardware/system/USB devices
