puleaudio testing microphone GUI

Hello: I would like to test my microphone in pulseaudio. All info I found say that I have to load manually the loopback module in a terminal to hear the microphone, and after testing unload the module. Isn't there a GUI tool which has button for testing/hearing the microphone? I don't even understand why this option is not part of pavucontrol of some other pulseaudio GUI program. Thanks, Istvan
