I'm having a trouble with my built in microphone. Even if I use headphone with mic, it doesn't really work. The weird thing is, if I clap the green lines of the speaker icon jumps, but if I speak it doesn't.

I have also tried some recordings, but I can not hear myself and adjusting the volume didn't help at all.

I tried to restore it, still no change.

I have updated it in the device manager, but it said there that it's up to date and the devices are working properly.

Until I decided to recover the whole system (wherein I pressed zero and switch on button) to my surprise, the settings became different, most programs were deleted, even my files. It's like it was formatted and I'm so sad that the mic was not fixed. I really don't know what to do now.

My laptop model is Toshiba satellite m840. I want to it return to its settings/set up just before I Recover the system and bring back all the programs that we're installed and of course, most of all, to fix my microphone so I can use Skype again and other video calling application.. I hope someone could help me. Thanks a lot!
