How do I re-install to get the audio fix?

This is simple to use, however, I could not get audio to record. I see there was a bug fix for the audio, how do I download the reparied version? My audio device is set to: built-in microphone, so it should have picked up my voice the voice of the Skype conversation comign from the speakers, it did not.
