Just to hack something up, it would be fairly easy to add a gain in the
speakfreely driver for the mic input, though a bit harder to make it a general
option. Would you like some source-code lines for that, or are you actually
looking for a neater option? I did write a software AGC at some point, but
have mothballed that code since I went to the hardware preamp for the better
audio quality it offered. A lot of soundcards seem to be pretty poor at
handling raw microphone connections.
