This has nothing to do with pulseaudio. The internal mic  is generally a
digital mic.
Using "alsamixer -c 0" should show an option to select the digital or the
analog (external)  mic. However, this depends on the alsa driver being used.
The current
stable version is 1.0.20, but Fedora is always behind.

I can select the digital mic on my Dell Vostro laptop, but the sound is too
low
to be useful, and I prefer to use the external anlog mic, than spenting days
on the
alsa development list because of that.
