Microsoft UAA Bus Driver for High Definition Audio
as a system device without a driver. However, I don't know where to get an 'official' driver for this 'device'. It just seems so generic. However, I noticed that when I had the video card in another machine, that machine required the same driver. Still, I've downloaded all possible video drivers and that device still needs a driver.Microsoft UAA Bus Driver for High Definition Audio
