The inbuIlt mic on my Fujitsu AH531 laptop has stopped working partially for sometime.The OS is windows 7 and the drivers and software are from Realtek . The problem is that whenever I open a recording program and try to record sound with it, the mic catches sound for a second or two and after that stops working.After that I tried speaking loudly placing my mouth near the mic port located on the laptop's lid near the webcam.Then It will catch sound.I have tried updating the drivers .The recording device setting have also been configured in the control panel but this don't seem to work.If it was a hardware problem the mic won't record at all, am I right ?And my headphone mic is working perfectly when plugged in.Can someone help me sort out this issue
