This problem is rather common from what I've seen on other fourms, but none of these solutions have worked so far. I've reinstalled Drivers, rolled them back, and this device works fine on other computers and other devices dont work on this computer. I can get audio through USB, but thats dodging around my Realtek High Definition sound card (Which right about now, I want to smash). The drivers from Realtek are no help, and I cant even raise their support line.
delete all your realtec drivers for audio and shut down your computer, and when you restart and get into your computer it should automatically try to re-instal them use that install, this worked for me before.
