This is most probably not a conflict in modules or audio drivers but
some setting that you have to make in the mixer for the soundcard (to
properly "route" the microphone to the soundcard). From the command line
you can use "alsamixer", I usually use gamix which has a gtk gui and
exposes all the controls a card has (with the exception of high end
cards like the rme). Search for something that is related to capture and
microphone, you usually have to enable (unmute) the channel and raise
the level. In cards like yours there's tons of settings and it is not
immediately obvious what you have to do to enable capture. 

I would also try something simpler to monitor levels than starting with
audacity. 

[of well, this might end up more complex... but here it goes anyway] For
example start jack (using qjackctl). That will show you which ports are
available. Then use meterbrige (it is a command line app) and connect to
those ports to get nice realtime vu meters. Then use gamix or your mixer
of preference to tweak settings in the card till you are able to see
activity on the vu meters...
