Microphone not working

[PIYUSH SINGH]

Hi ,

I have a HP CQ45-207TU notebook. and from yesterday my micorphone isn't working.
Here are the screen shots of
Alsamixer                             http://imagebin.org/250567
Alsamixer Capture Devices     http://imagebin.org/250569
pavucontrol                           http://imagebin.org/250570

I am not able to figure out what the problem is and when i tried using
the sound recorder to record sound to check if its working or not
.It's not recording.

Thanks in advance for help.

With Regards,
Piyush Singh
