First of all, you will need to use some other profile than surround. So start by switching to stereo output (or stereo duplex) profile in pavucontrol's Configuration tab. If after that Mic or Line-In doesn't work automatically, you will also need to change the source port to Mic or Line-In. Pavucontrol should have a port selection somewhere, probably on the Input Devices tab. I can't check, because pavucontrol crashes my pulseaudio (yes, I should fix or at least properly report that bug...). If you don't have any relevant source ports available for selecting, give the output of "pacmd list-sources" and "amixer -cX" (the X in amixer -cX is the sound card name, which can be found inside the square brackets in /proc/asound/cards). -- Tanu Kaskinen
