I have a dell inspiron 1521. Dual 1.8g processor. 2g ram. Windows vista home premium. I have been having problems with both the built in microphone and any headset that I plug into my laptop. I have been looking through windows but it doesn't seem to recognize the built in microphone anymore and doesn’t want to recognize the headset I plug in either. When I plug in my headset I normally got the beep that I plug something in, and a window would pop up asking what I wanted to use that jack for, and I always selected the mic. option. It started when i updated the audio driver. I restored vista to a previous point before the driver update and nothing happened. The only file that i suspect of is ntoskrnlg.exe, it was modified the same day and time of the driver update. Thank you
