Pulsesrc element comes from the gstreamer1.0-plugins-good package.
Have you installed it?

Please install (or reinstall) these packages. Run this command in a terminal window.
Sudo will ask your login password.

sudo apt install --reinstall -y gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly

Test the recording pipeline. Install first gstreamer1.0-tools package.
sudo apt install -y gstreamer1.0-tools

Now play some music or sound (out of loudspeakers) and test-record it with:
gst-launch-1.0 pulsesrc ! audioconvert ! vorbisenc ! oggmux ! filesink location=test1.ogg

Press CNTR + C to stop the recording. Then replay the result (test1.ogg) file.
totem test1.ogg

You may also test various recording-pipelines on the command line.
Click the [Additional settings] button, t select the "Recording commands" tab and [Show cmd] button. Please see:
