Do you mean the "Input Devices" tab?

Is even silence recorded? On the "Recording" tab of pavucontrol, do you
see the gnome-sound-recorder or skype stream, and does the UI say that
it's connected to the usb headset microphone?

The log shows that udev reports the device getting repeatedly removed
and added, so that problem is at a lower level than pulseaudio.

It's certainly possible to disable the internal sound card in
pavucontrol. Go to the Configuration tab and select the "Off" profile
for the internal card.
