Do you have "Wave Out" ??? If you do basically those who don't have "Stereo Mix", use the "Wave Out" option, a replacement for VISTA users.

To enable Wave Out in Windows Vista:

1. Click the "Start" and open the "Control panel"
2. Click "Classic view"
3. Double click the "Sound"
4. Select the "Recording" tab
5. Right click on the "Wave Out" and make it default.
6. Click "OK"

Or you also try to "Show Disabled Devices" and "Show Disconnected Devices".
To enable disabled Stereo Mix in Windows Vista:

1. Click the "Start" and open the "Control panel"
2. Click "Classic view"
3. Double click the "Sound"
4. Select the "Recording" tab and right click any of the devices listed
5. Check "Show Disabled Devices" and "Show Disconnected Devices"
6. "Stereo-mix" , "Wave Out", "Mono-mix" or "What-you-hear" should show up. Set it as a default.
7. Click "OK"

If the "Stereo Mix" doesn't come up after you do the above, it may be disabled at hardware or driver level.
