In the alsamixer window, note the "View" field in the top-left corner.
You can hit F3 to show just playback, F4 to show just Capture, or F5 to
show all. I think what you have unmuted is the playback of your
microphone. You want to look at the Capture screen and make sure that
the microphone is unmuted and set to an appropriate level (set it really
high for testing).
The playback (or monitoring) level of your microphone is independent of
the capture level of your microphone.
Some sound cards also have choices for whether your input is a
microphone or a line-in jack. Those cards can process input from either
source, but not both at the same time. A microphone source requires
more amplification than a line-in, so you probably want to have
"microphone" selected, rather than "line-in".
Good luck!
