So, I have an musical instrument that can be recorded using Audacity through the mic jack on my laptop,but I can't hear it while I play it. That's the whole point of having instruments right?
So I tried a few things
-the whole "Software playthrough" thing in Audacity and it didn't work.
-Alsamixer pretty much had some things look cool and technological, but ultimately did not help me when I raised levels and checked for muting.
- I kind of lightly punched everything too, obviously did not work either.
- I installed JACK and it did not have anything in terms of an input idea, gave me a few errors and a bit of a headache.

I have an hp pavillion g4, if that helps at all. Thanks for your time, in advance.
