I had a problem with a *missing* internal microphone today (well, I spotted it today - probably been like this for ages...).
Note that this was PulseAudio saying that there were no input devices.

The problem (as I eventually spotted) was that I'd set the Profile to be Analgue Stereo Output (under Configuration in PA Volume Control).

Setting this to Analogue Stereo Duplex made the internal mic show up.

Might not be the problem for most people, but you never know.
I did notice that if I plugged in an *external* mic the Profile switched to Duplex automatically.
