(code 45) high definition audio devices not found

I have two high definition audio devices in the device manager that states: Currently, this hardware device is not connected to the computer. (Code 45) To fix this problem, reconnect this hardware device to the computer. How to fix it? A Microsoft agent
suggested that I uninstalled it from the device manager, restart it and it should automatically install. Now, it is gone. Can't find it in the device manager. How to get it back?
