I'm using Realtek HD Audio Manager presumably part of the drivers for my motherboard's audio, but at seemingly random intervals the notification area keeps coming up with "You just unplugged a device from the audio jack." The only audio I am using is going through an HDMI cable and nothing is being unplugged. This message is a bit irritating and I would appreciate any help in finding a solution. Thanks.
