Built-in microphone not detected?

Solution 1:

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.

Solution 2:

Take a look at this:

Original answer by @Treviño, Posted here for your convenience:

The only way I've found to make my internal mic work in my laptops is to use pavucontrol (install it from the homonymous package) and disabling the volume of a channel (the right or the left one), since most of microphones are mono in fact.

This is an huge workaround, by the way. I guess that this annoying bug should be fixed somewhere!

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).

Under Sound Preferences, please post the "Hardware Tab" in order to check your profile, which should use at least an output + an input being in use. Otherwise, your hardware is not using the input profile which can be chosen right there.
