Is it also possible to include your audio equipment? Also make sure that your BIOS and remaining device drivers are up to date.

In your sound Manager,
Start>type Control Panel and press enter>Sound

click on Recording tab and locate your Stereo Mix device upon which you'll need to right click and go to properties. You should see a "Levels" tab
