Hi Maniak!
I’m about to upgrade to Windows 7 myself, as other customers are bound to do the upgrade now as well.
However, the first thing I can think of is, first of all, make sure something is physically plugged into the Realtek output — for example speakers or headphones.
Then, try to go through the wizard again. If you see the expert settings as below:
Click the Wizard button.
If you don’t see the device in the list, then make sure Safe Mode is checked. You *should* see it in the list then.
Please let me know if this solves the problem.
Best,
///Leif
