You haven't stated whether your audio still works ok. The message means either the onboard sound in your computer is faulty, or there is a driver issue. I'd start by uninstalling and reinstalling the device. If the problem persists, seek updated drivers for this device, or if you have recently updated the driver, try rolling back to the previous one. If none of these work, its likely you have a hardware issue. If the audio works, and the popup isnt there every time you use the audio, then it may be easiest to just live with it. If it really bugs you, since its an onboard audio issue, the easiest way to fix a hardware issue is to permanently uninstall it and fit an aftermarket sound card.Another thing that is possible is that you have installed something else recently thats creating a conflict. Have you recently added anything that can access audio, like a webcam ?
