Please don't yell at me for necroing an old thread, but I just ran into this issue and because this was the first thing that popped up, I wanted to make sure this question was actually answered.
If your mic is not picking up, more than likely, you do not have your mic selected in the Pod Farm 2 software. Click the "Mixer View" button in Pod Farm and under the first Input drop down menu, make sure "Mic 1" is selected.
