The problem is that the Sigmatel 92XX audio driver for Windows Vista from Dell doesn't have the "Stereo Mix" option. But you can try to download the driver for Windows XP. Run the driver in Windows XP compatibility mode and it should work in Windows Vista.
Please don't try to install the driver if you don't have the Sigmatel C-Major 92XX HD Audio!!!
