Ubuntu Multimedia :: PulseAudio - Mute Mic Output Through Speakers

I don't want to monitor my inputs. In other words: My microphone input plays through my speakers, adding a lot of undesirable noise from the mic. I can mute the mic inputs in alsamixer and/or in the Pulse volume control. This works to get the mic out of the speakers--but it also mutes my mic entirely, so I cannot record audio or use Google Talk. I want the microphone muted in my output, but available to my apps.

(I try to get on the Pulse bandwagon but it is so hard--I thought this was exactly what it was supposed to do, give easy mixing control over inputs and outputs. But I have to search for "fixes" with every single Ubuntu release for two years now, ever since it was first included. Ok, venting over, time to get it working!)
