I have 2 of these monitors (2 different users) and every few days the built in microphone is not detected by the PC. (Both users on desktops SFF Plus 720 via DisplayPort, USB type A to B )

- Only way to bring back the microphone is to power cycle the monitor. (Disconnect from power, reconnect)

- Drivers, all Dell software up to date. 

Anyone else experiencing the same issue?
