My built-in microphone doesn't seem to be detected, because I cannot use it to record my voice in Audacity and it's also not working in Skype.
Any solution for my problem?
Laptop: Axioo MNC
I found that if I opened up the
Applications > Sound and Video > PulseAudio Volume Control
and under 'Configuration' changed my computer from 'Analog Stereo Output' to 'Analog Stereo Duplex', the mic was recognized and now works. This also resulted in the
System > Preferences > Sound
settings box showing the mic, whereas it did not show up before.
As suggested by the comments: make sure that you have set the microphone as input sound device in the sound preferences.
If the microphone still won't work, make sure it's enabled in the BIOS setup and that you haven't turned it off via some Fn-shortcuts of your notebook.
This could be a regression bug that I reported in 2009 and has not yet been solved. I asked a the same question before here and here. I didn't find any solution. I wonder if you have the same Intel 82801H sound card.
I had to buy an external USB mic.
I gave up on built in microphones. When I use skype or other type programs I use a bluetooth headset that I also use with my cell phone. If your laptop does not have bluetooth you can add a USB bluetooth dongle. You can find them for a cost from $15 to $30. They are tiny so it can be left plugged in all the time. Most headsets have a technology called multipoint which allows you to pair with more than one device simultaneously. When I need to make a skype call I press the call button on the headset and it connects to the bluetooth service on my computer and takes over the speaker and mic feature. Since it is basically wireless headset I can walk away from the computer while still in the call.
I know this does not specifically answer your original question but may give you a better option.

It worked for me in several laptops with stereo and/or mono built in microphone (on screen or panel).
Additionally, you may wish to take a look at your sound preferences, mentioned in the same page. Click this link: Skype doesn't find my audio input (this will lead you to a different answer in the same page).
