In amixer it's not that obvious

may be you'll need to learn about alsa, or pulse audio (which will be the
interface of the future)

this means you have one built in mic ( a booster to it - it adds some db -
usually not needed)
then you have 3 other inputs that you can use.
you can usually setup one for recording at a time but perhaps jack or
something like audacity can use all 3 at a time.
changing the input source in alsamixer will do the job i.e.

I would change to
