@Raymond Cirrus7 PC manufacturer responded to my question by e-mail (see below).
###start e-mail thank you for reporting! Can confirm problem with Pink Jack. Changing VREF from HIZ to 50 with hda-analyze (http://www.alsa-project.org/main/index.php/HDA_Analyzer) works for me. Close hda-analyze and choose "no" on last screen After That I can record with microphone with line-in on pink jack (my headphone has a pink stereo jack) I'm still having trouble making settings permanent. (After reboot everything is reverted back) I have a USB Headset, so I never connected a Mic on the pink Jack It is a multi purpose jack. One can also use it for output ... ###end e-mail "do cirrus7 computing specification/user mention that the pink Jack is line in ?" --> so it is a multi purpose jack "how many audio jacks in the computer ?" --> The case only has a green line out jack and a pink "multi-purpose" jack. They are both at the back side. "MicJack need vref 50 or 80" --> Setting VREF to 50, as suggested in the e-mail helped. However, quality was sub-ideal and changes were not permanent. "you can either use hda-analyzer change the pin ctls or hda-jack-retask to retask line in as Mic" --> see solution with hda-analyzer above. I cannot find hda-jack-retask nor hda-jack-sense-test. Some instructions might be helpful.
