Can I see your recording tab, for reference please?

I searched for audio drivers for your system and was unable to find anything directly related to your board. the Sound card is built in and is the IDT 92HD202. The only drivers I can find are for the 92HD series that were put into Dell Precision 5400 laptops. Those drivers stopped at Windows Vista. Chances are, since IDT has discontinued the manufacturing of hte 92HD series chip, you won't find Windows 7 drivers.

I am fed up of search supported drivers for my pc.
hope u can help me out.
