Just installed a new DH67GD motherboard in an Antec Three Hundred case with analog speakers attached to the rear connector and installed windows 7. I keep getting a pop that states: "You just plugged a device into the audio device." It has check boxes for Headphones and Front speaker out. The Realtec HD Audio Manager also pops up and shows the analog connectio in the rear and the front panel indicators flash. This occurrs with the audio connector from the front panel connected to the motherboard or if I disconnect the connector.
Any thoughts ideas? I reinstalled the audio drivers and rechecked all the connectore.
